System overview1.3 BD01 systemConnection methodThe assembly of the trunking units – even with the end caps and feeder units – is fast andinherently safe. The trunking units or end caps are simply inserted into the lower housing ofthe joint block. Once the upper part of the joint block or end cap is fitted, a secure connectionis established by simply tightening the four screws.Figure 1-7Establishing a safe connectionTap-off unitsTap-off units are available in four different sizes to connect the loads and also with variouscomponents fitted, e.g. such as plugs, fuses, miniature circuit-breakers or combinations ofthe aforementioned.Figure 1-8Tap-off unit BD01 systemAncillary equipment units offer additional space for decentral function expansions. Thus,automation and control components can be installed directly on the busbar.Fixing and mountingThe BD01 busbar is installed edgewise, with the tap-off points on the side using fixingbrackets on the wall, ceiling or non-fixed installation. The mounting is implemented on theconnection points using a universal fixing bracket. The system can also be fitted flat with thetap-off points pointing downwards. This reduces the required fixing interval by half.Figure 1-9Mounting the BD01 systemPlanning with SIVACON 8 PS18 Planning Manual, 10/2007, A5E01541101-01

System overview1.4 Networked busbar trunking systems for industrial and building applicationsFire protectionIf the busbar trunking system is routed through a fire wall or ceiling, it must have fireprotection. Compliant with site requirements, Siemens offers fire protection class S90.Ex-works equipment:● External fire protection in the form of a kit for on-site mountingMineral mortar or fire protection mastic to seal the joints between busbar trunking systemand component must be provided by the customer.Figure 1-10Fire protection BD01-S90The approval documentation for Germany can be ordered separately:● Approval kit BD01-S90-ZUL-D(approval certificate, wall signage and declaration of compliance)1.4 Networked busbar trunking systems for industrial and buildingapplicationsThe advantages of busbar trunking systemsThe busbar trunking system has its advantages in the transport, distribution as well asswitching and protection with electrical energy.Integration of automation and building systems engineering into the Siemens busbar trunkingsystems results in further advantages and also increases the flexibility of the busbar trunkingsystem.The combination of standard tap-off units with standard ancillary equipment units guaranteesenhancement in efficiency with the design, installation and operation.The advantages of the system solution for planning● Modular system● Tested standard components● Freedom in the selection of the bus system● Use of most popular bus systemsPlanning with SIVACON 8 PSPlanning Manual, 10/2007, A5E01541101-01 19

System overview1.4 Networked busbar trunking systems for industrial and building applicationsThe advantages of the system solution during commissioning● Quick and simple installation● Step-by-step commissioning possible● Flexibility in terms of changes and expansionsThe advantages of the system solution in operation● Transparency of circuit states● Energy costs recorded centrally● Increase in system availability thanks to immediate detection of error location and type● Preventive maintenance as operating hours and switching cycles are recordedSystem concept networked busbar trunking systemsThe tap-off units available as standard for busbar trunking systems can be combined withstandard ancillary equipment units to create a system solution for networked busbartrunking. For reasons associated with design, an ancillary equipment unit based on a BD01ancillary equipment unit is used for the BD01 busbar trunking system. A universal ancillaryequipment unit suitable for the application in question is used for BD2, LD and LX systems.Standard applications are factory-assembled prior to delivery by combining tap-off unit andancillary equipment unit as appropriate. The bus line for the transmission of data signals islaid in a cable channel mounted on the trunking unit.Figure 1-11Switching and signalling with the BD2 systemPlanning with SIVACON 8 PS20 Planning Manual, 10/2007, A5E01541101-01

Planning principles 22.1 Structure of the planning manualIt is not by any means easy to plan a power distribution concept involving the dimensioningof systems and devices. End user requirements have to be matched with the technicalcapabilities of the manufacturer. This planning manual will provide assistance as you planand design the following busbar trunking systems from 160 A to 6300 A:● BD2A/BD2C● LDA/LDC● LXA/LXC● LRCDescription of the individual systemsEach system has a dedicated chapter describing its technical characteristics and areas ofapplication. Illustrations of the individual busbar trunking system elements also appear. Allsignificant information relevant to the planning process is given particular emphasis andexplained in detail.Further informationYou will find advice to help you to develop a ready-to-use planning solution under "Furtherinformation". These include specific dimensioning principles and detailed information abouttopics such as fireproof barriers and functional endurance.Siemens can offer a range of services and engineering tools to assist you in drafting yourspecification.

Planning principles2.2 Busbar trunking system planning2.2 Busbar trunking system planning2.2.1 Principles of busbar trunking system planningDecision-making criteria affecting the creation of the power supply conceptWhen drafting a planning concept for a power supply, in addition to the applicable standardsand regulations, you also need to clarify and address issues of cost and technology.Accordingly, when dimensioning and selecting electrical equipment such as distributionboards and transformers, rather than focussing on them individually, you need to aim tooptimise their performance as part of a combined system.All components have to be dimensioned sufficiently for loads both in rated operation and inthe event of a malfunction. Furthermore, you must take the following important issues intoconsideration when drafting a power supply concept:● Building type, use and design (e.g. high rise, low rise or number of storeys)● Determination of load centres, identification of possible supply routes and locations fortransformers and main distribution boards● Calculation of the building's effective installed loads according to specific area loads asappropriate for the building's use● Planning authority regulations and requirements● Requirements set out by the utility companyRequirements to be met by power supply conceptsPlanning will never produce just a single option for a solution. Rather, you will need toassess a number of possible options on the basis of issues relating to technology and cost.The following requirements are major factors:● Simple and transparent planning● Long service life● High availability● Low fire load● Flexible adaptation to changes in the buildingThe solution: Siemens busbar trunking systemsIn most applications, these requirements can easily be solved by using suitable busbartrunking systems.It is for this reason that busbar trunking systems are increasingly being preferred to cabletrunking by engineering consultants charged with designing systems for power transmissionand distribution. Siemens offers busbar trunking systems from 25 to 6300 A:Planning with SIVACON 8 PS22 Planning Manual, 10/2007, A5E01541101-01

This is particularly true ofautomated facilities.The ability to retrofit new equipment or modify existing resources without interrupting activeproduction is not only important for the continuous provision of the electrical power supply. Itis also a vital requirement for production facilities operating on a multiple shift basis.Increased safety and complex systems require a power distribution system which is able torespond to all requirements associated with costs and technology.The CD-K, BD01, BD2A/BD2C, LDA/LDC, LXA/LXC and LRC busbar trunking systems aretype-tested low-voltage switchgear assemblies (TTA) compliant with DIN EN 60439-1 and -2.The CD-K, BD01, BD2A/BD2C and LDA/LDC systems consist of busbars, internal barfixings, an external enclosure, fixing and connection accessories.

Planning principles2.2 Busbar trunking system planningand the LRC cast resin system consist of busbars, fixing and connection accessories and aninsulating foil, along with an aluminium enclosure (LX) or an enclosure made from epoxyresin (LRC).Figure 2-2Trunking unit: power supplied via a busbarPower transmissionComponents of the busbar trunking system transmit power between transformers and lowvoltage power distribution systems and from the main distribution board to the servicedistribution board. Trunking units without tap-off points are used for the power transmission.In addition to thestandard lengths, customers can select lengths from several ranges to meettheir particular building requirements.Power distributionThe main application of busbar trunking systems is power distribution. Current can't be takenfrom just a single point which is permanently installed such as a cable installation. Currenttap-off units can be moved to any position within the entire system. To tap power at anygiven point simply requires positioning a tap-off unit at that location on the busbar.The result is a flexible distribution system for decentralised power supply to a particular lineor area. Tap-off points can be mounted on one or both sides of straight trunking units.Depending on the requirements of the particular application, busbar trunking units with tapoffunits for a rated current of 1250 A from a single tap-off point are available for tapping offpower and connecting loads. The tap-off units can be equipped with fuses, fuse-switches,miniature circuit-breakers or circuit-breakers as desired.On all Siemens busbar trunking systems, the tap-off units can be changed withoutdisconnecting the busbar trunking run. The following requirements apply:Planning with SIVACON 8 PS24 Planning Manual, 10/2007, A5E01541101-01

Planning principles2.2 Busbar trunking system planningMandatory requirements● The PE contact on the tap-off unit leads during installation and lags during removal.● The parts which are live during installation, removal or connection have completeprotection against direct contact (degree of protection IP2x).● Installation requires phasing to be correct.These mandatory requirements are of course met by the BD2A/BD2C, LDA/LDC andLXA/LXC systems.Optional requirement● Voltage-free components during installation and removal.This optional requirement is met by the BD2A/BD2C, LDA/LDC and LXA/LXC systems.Exception: BD2-AK02(03) tap-off units and BD2 tap-off units with fuse bases.Figure 2-3Tap-off units for flexible current consumptionPlanning with SIVACON 8 PSPlanning Manual, 10/2007, A5E01541101-01 25

Planning principles2.2 Busbar trunking system planningPlanning made easierEasy to plan, quick to install and flexible to use: Siemens busbar trunking systems are anefficient means of supplying power to any building. Power distribution can be plannedprecisely on the basis of total connected load and the type and number of loads. Planningtools such as SIMARIS design provide assistance. The line topology with load feedersarranged at regular intervals ensures transparency. All applications can be implementedquickly and compactly with standardised sizes.In a cable trunking system, new loads haveto be connected via an additional subdistributionboard; this costsboth time and money.On busbar trunking systems, tap-off units inthe vicinity of loads ensure localtransparency.Increased safety due to high short-circuit rating and minimum fire load.Advanced safety – both in respect of short-circuit rating and where fire load is concerned.BD2A 250 busbar trunking systems, for example, have a fire load of just 1.32 kWh/m,whereas comparable cable trunking systems (NYY 4 x 95/50 mm2) are rated at 5.19 kWh/m.Furthermore, the busbars are halogen-free. Siemens busbar trunking systems feature highshort-circuit rating. Furthermore, troubleshooting is made easier thanks to local loadshort-circuit protection.High fire load with cablesLow fire load with busbarsPlanning with SIVACON 8 PSPlanning Manual, 10/2007, A5E01541101-01 27

Planning principles2.4 System selection criteria2.4.3 Selection on the basis of rated transformer dataFigure 2-4Connection of a transformer to a Siemens power distribution boardThe table can be used to select the appropriate busbar trunking system on the basis of thetransformer's rated current. The short-circuit rating of the LDA/LDC, LXA/LXC and LRCbusbar trunking systems is usually higher than the values for the transformer's sustained andpeak short-circuit currents. However, this only applies if just a single transformer is used forthe low-voltage supply. Higher short-circuit values are possible on ring or meshed networksor if transformers are connected in parallel in a low-voltage switchgear assembly.

Planning with BD2A/BD2C3.2 System componentsThe BD2A/BD2C busbar trunking system is suitable for universal use. Designed forapplications involving flexible power supplies and power distribution for consumers inindustrial and commercial environments, it can also be used to transmit power from onesupply point to another. In addition, the BD2 busbar trunking system can be used as a risingmain busbar in high rise buildings.3.2 System components3.2.1 Preliminary technical descriptions for specificationsThe BD2A/BD2C busbar trunking systems can be offered as type-tested low-voltageswitchgear and controlgear assemblies (TTA) to IEC/EN 60439-1 and -2.The brand offered represents a complete system consisting of system modules, includingelements for connection to the distribution boards such as brackets, straight trunking units,e.g. T connectors and flexible junction units.Trunking units with tap-off openings can be equipped with coded tap-off units. Tap-off unitsare protected against incorrect mounting. Depending on the type, the isolation of the tap-offunits during dismounting is assured by positive drive of the operating sequence or byinstructions which detail the cautionary measures involved.If necessary, it is possible to equip the busbar trunking system with an asbestos-free firebarrier which conforms in the case of BD2C to the fire resistance class S 120 and in the caseof BD2A to S 90 or S 120. The trunking unit's steel enclosure is made of moulded steelprofiles to permit large fixing distances between suspension points. The enclosure is paintedin a light grey colour (RAL 7035).The external dimensions may not exceed 68 x 167 mm up to 400 A or 126 x 167 mm up to1250 A. The connection of the individual systemmodules is implemented with state-of-the-artquick connection terminals with integral compensation for expansion. The system isprotected against phase inversion. A mechanical, electrical and maintenance-freeconnection between two busbar trunking system elements can be established quickly andsafely using conventional tools.The conductors are made of aluminium or copper. The aluminium conductors must benickel-plated and tinned along their entire length. The copper conductors must be tinned.The fire load should not exceed the value stated in the technical specifications. Expansioncompensation must be integrated into eachtrunking unit. Busbar trunking units should beable to be mounted both horizontally and vertically. Junction units may not be used toconnect cables.. Flexible junction unit are permissible as system modules of the busbartrunking system.The following declarations of conformity must be included with the offer:● DIN ISO 9001 QA certification● Proof of absence of halogen● Certificates verifying– that the fire barrier has been tested and approved– that functional endurance has been tested and approvedPlanning with SIVACON 8 PS36 Planning Manual, 10/2007, A5E01541101-01

See technical data.2) Please delete as appropriate.NoteThe innovative design and construction of the BD2 busbar trunking system means thatadditional compensation units to compensate busbar expansion are not required. Prevailinglength expansion caused by current heat is compensated in the quick connection terminal.Furthermore, regardless of mounting position and degree of protection, the BD2 busbartrunking system can always be loaded at 100% of rated current. This only has to be reducedin the case of pure power transmission in the edgewise mounting position (to 0.9 x Ie).Planning with SIVACON 8 PSPlanning Manual, 10/2007, A5E01541101-01 37

Theincoming supply can be set up as an end feed or a centre feed.3.2.5.1 End feeder unitsCommon featuresAll end feeder units have the following common features:Cables can be fed in from the front end. Units with cable compartments support cable entryfrom the side. In the case of multi-core conductor entry, a sectional entry flange with cablesleeves and cable propping bar is standard; in the case of single-core conductor entry, analuminium plate is standard. The cables are connected using lugs and bolts. The bolts aresupplied with the unit. When connecting 5-conductor cables you will need to remove thebridge between PE and N which will have been fitted prior to delivery.

Planning with BD2A/BD2C3.2 System components3.2.5.2 Centre feeder unitsCommon featuresAll centre feeder units have the following common features:Cables can be fed in from three sides. The sectional entry flange with integrated strain reliefcan be converted to these positions. Aluminium cable entry plates for single-core cables asan alternative option. The cables are connected using lugs and bolts. When connecting5-conductor cables you will need to remove the bridge between PE and N which will havebeen fitted prior to delivery.Figure 3-6Centre feed160 ... 400 A BD2.-400-ME630 ... 1000 A BD2.-1000-ME160...400 A BD2.-400-ME-MBAL630...1000 A BD2.-1000-ME-MBALImportant planning information:A centre feed might be the best option for the distribution of high powers with small busbarcross sections. It is mounted in the centre of a trunking run between two trunking units. Asingle power supply cable provides power to the left-hand and right-hand trunking runssimultaneously. This means, for example, that a 1000 A centre feed can feed in 2000 A. Insuch cases you need to pay particular attention to the busbar system's overload andshort-circuit protection.You will need to provide protective measures in the following instances:● If short-circuit protection is not being provided by the upstream protective device and/or● If the overload is not set by the type and number of loadsThere are two possible protective measures:1. Use a centre feed unit with one coupling unit on the left of the incoming feeder andanother on the right. The coupling unit is fitted with a protective device (fuse orcircuit-breaker) providing short-circuit and overload protection.2. Use two end feeder units located in the centre of the trunking run. The two supply linesare fused separately in the distribution system.Planning with SIVACON 8 PS46 Planning Manual, 10/2007, A5E01541101-01

Planning with LDA/LDC4.2 System componentsThe LD busbar trunking system is used for both power transmission and distribution. Thesystem offers a high short-circuit rating and is particularly suited for the connection oftransformers to low-voltage main distribution boards and sub-distribution boards. Inapplications where high powers are required, conventional systems frequently require theuse of parallel cables. The LD system offers optimal power distribution for both horizontaland vertical busbar runs.4.2 System components4.2.1 Preliminary technical descriptions for specificationsThe busbar trunking systems should be offered as type-tested low-voltage switchgear andcontrolgear assemblies TTA to IEC/EN 60439-1 and -2, DIN VDE 0660 Part 500 andPart 502 (German standard), as a steel-encapsulated ready-to-connect system.The distribution systems must be suitable forpower transmission, e.g. between transformerand low-voltage main distribution boards, as well as for power distribution providing a supplyof power to an entire area.The brand offered must be a complete system consisting of system modules, includingtransformers and elements for connection to the distribution boards, as well as such asbrackets, straight trunking units and junction units. All components should be available bothin straight and offset versions.Trunking units with tap-off openings should be able to be equipped with coded tap-off units.The tap-off units must be protected with coding brackets to prevent incorrect mounting.Isolation of the tap-off units during dismounting should be assured via positive operatingsequences.If required, the busbar trunking system should be capable of being equipped withasbestos-free fire barriers which comply with fire resistance class S 120, and which havebeen certified by the local or government authority responsible for building standards. Thetrunking unit's steel enclosure is made of moulded steel profiles to permit large fixingdistances between suspension points. Theenclosure is galvanised and painted in a light greycolour (RAL 7035).The external dimensions may not exceed 180 x 180 (240) mm.The individual system modules are connected by hanging a hook from a bolt and tighteninga state-of-the-art maintenance-free single-bolt clamp. The conductor between two systemunits should not be connected with screws.The conductor material is made of aluminium or of copper if the rated current requires.Thealuminium conductor must be nickel-plated and tinned along its entire length, the copperconductor must be tinned and provided with an additional insulating layer of epoxy-resin.The fire load must not exceed the value specified in the technical data. Expansioncompensation units and fixed points should be engineered based on their requirements andbusbar run (horizontal mounting). In the case of vertically mounted trunking units, acompensation unit and fixed point must be integrated in every system module. Junction unitswith flexible connections or cable connections are not permitted.Planning with SIVACON 8 PS104 Planning Manual, 10/2007, A5E01541101-01

See technical data for values.2) Please delete as appropriate.Important planning informationThe nominal mounting position of the busbar trunking system is horizontal and edgewise forthe busbars. In very rare cases, due to a specific trunking run or the option of connectingtap-off units on the side, the busbars might have to be laid flat. The resulting increase in theinternal heat rise of the system necessitates a reduction in rated current. The same appliesto vertical height rises > 1.3 m (see the table in the next section "Type codes").The LD busbar trunking system is a ventilated system. When the degree of protection isincreased from IP34 to IP54 (enclosed system), the rated current must be derated asspecified in the tables in the next section.Planning with SIVACON 8 PSPlanning Manual, 10/2007, A5E01541101-01 105

Planning with LDA/LDC4.2 System components4.2.2 Type codeDefinition of the required system using the type codeThe basic components of the LD system are determined using a type code. The type isspecified and selected on the basis of rated current, conductor material, system type anddegree of protection.The resulting type code enables the required system to be precisely defined.

Planning with LDA/LDC4.2 System componentsNoteExpansion compensationDue to heat dissipation at rated load, the busbars in the trunking unit expand. Tocompensate this expansion in length, you need to include expansion compensation units atdefined intervals when planning your horizontal installation.In the case of vertical installation, each trunking unit features expansion compensation.When planning expansion compensation for trunking units, please remember:• A straight trunking run without expansion compensation between two junction units mustnot exceed 10 m in length.• A straight trunking run between a junction unit and the end cap must not exceed 25 m inlength. In the case of longer trunking run lengths, planning provision has to be madeaccordingly for expansion compensation units.123BoltExpansion compensationHookTrunking unit with expansion compensationTap-off pointsTap-off points are only possible on straight trunking units (both standard lengths and optionallengths possible). Options are:● Tap-off point on TOP: ...-AD● Tap-off point BOTTOM: ...-ADU● Tap-off points on TOP and BOTTOM: ...-ADO+UWith a trunking unit with a tap-off point at the TOP and BOTTOM, only one tap-off unit canbe used at a time. The required distance between tap-off points is 1 m.Planning with SIVACON 8 PS112 Planning Manual, 10/2007, A5E01541101-01

Planning with LDA/LDC4.2 System componentsThe required type should be determined during engineering, based on the mounting positionof the busbar.In the case of optional trunking units with tap-off point, a minimum clearance of 0.6 m isrequired between the end of the busbar and a tap-off point.A coding bracket is located on both sides of a tap-off point. This guaranteesnon-interchangeability and correct phasing sequence installation of the tap-off units.Figure 4-4Trunking unit with tap-off pointPlanning with SIVACON 8 PSPlanning Manual, 10/2007, A5E01541101-01 113

In this design, the tap-off unit is supplied with adoor.Figure 4-10Degree of protection IP54Cable compartment/cable entryA bolted connection is used for cables with cross sections up to 2 x 4 x 240 mm 2 . Cables canbe fed in on both sides. In the case of a single-core cable entry, an aluminium plate fittedwith metric screwed joints is included in the scope of supply.Resistance to arc faultsThe tap-off units are resistant to arc faults. This has been verified by means of accidental arctesting to IEC 439-1 Supplement 2, EN 60439-1 Supplement 2, VDE 0660 Part 500Supplement 2 and confirmed by a test report.Type designationThe type designation for tap-off units with NH switch disconnectors is LD-.AK./FS.Planning with SIVACON 8 PSPlanning Manual, 10/2007, A5E01541101-01 123

Planning with LDA/LDC4.2 System components4.2.11.3 Tap-off units with circuit-breakersOn tap-off units with circuit-breakers you can select the switching capacity, the number ofactively switched poles, the type of operator control and the signalling options:● Rated currents from 80 A to 1250 A● 3 or 4-pole designs● Switching capacity: normal, standard or high (see Technical data)Circuit-breaker with manual operating mechanismThis type of tap-off unit has a circuit-breaker which can be controlled from the outside usinga handle.Degree of protectionThe tap-off units have IP54 degree of protection.Opening the tap-off unitThe contact compartment and the copper connections between the contact mechanism andthe circuit-breaker are encapsulated in a finger-proof casing. The cover can only be openedif the breaker has been deactivated. This ensures voltage-free load when the cover isremoved.Cable connectionOn the load side, the outgoing cables are routed directly via the circuit-breaker or optionallyvia terminals. The PE/PEN conductor is fixed to a bolted connection as appropriate for thecross section. Single-core or multi-core cables can be fed in from the side or via the frontface. The sectional flange plate facilitates the laying of the cables.Circuit-breaker with door handle, also available with motor driveThis version has a motor drive instead of a door handle.Figure 4-11Circuit-breaker with door handle, also available with motor drivePlanning with SIVACON 8 PS124 Planning Manual, 10/2007, A5E01541101-01

Planning with LXA/LXC5.2 System components5.2.8 Connection unit for non-Siemens distribution boardsIf you wish to connect the busbar trunking system to a non-Siemens distribution board, youcan establish this connection using an LX connection unit for non-Siemens distributionboards .... . The connection unit is built into the distribution board and serves as an interfaceto the copper connections of the distribution system.VersionsCopper conductors are usually used for connection units for non-Siemens distributionboards. Depending on system type, a total of eight different conductor configurations areavailable for selection. The rated currents up to a maximum of 5000 A correspond to thedata in the Technical data section. In accordance with DIN EN 60439-1 and -2, thetemperature limit in distribution systems in the event of heat rise must not be exceeded bythe current heat. The temperature limit of the bars, which are enclosed in insulating material,is 135°C. The required conductor cross sections for the copper connections are also listed inthe Technical data section.Installing the connection unitThe connections in the distribution board must be copper-plated by the board manufactureror in compliance with that manufacturer's specifications. The board manufacturer mustensure that the required short-circuit rating is achieved and the permissible temperature limitof the non-Siemens connection unit is not exceeded.Figure 5-3Connection unit for non-Siemens distribution boardsPlanning with SIVACON 8 PSPlanning Manual, 10/2007, A5E01541101-01 159

Regardless of mounting position, the enclosureensures IP54 degree of protection (IP55 can be achieved with the appropriate accessories).All units are fitted with either a fuse switch disconnector or circuit-breaker with handle as wellas bolts for the cable connection. For conductor systems (conductor configurationsaccording to type LX...6.) with insulated PE conductor, the tap-off units are supplied with theaddition of a separate PE connection.Cable entryCable entry can be from the side or front (exception: for tap-off units up to 250 A from thefront only). Integrated flange with cable sleeves facilitates multi-core cable entry. Aluminiumplates are used for single-core cable entry; these have to be fitted with cable glands locally.Safety during operationThe tap-off units cannot be opened unless the protective device is switched off manually.Once this is done, the cable connection area is no longer energized. The part of the contactdevice in the front of the tap-off unit is "finger-proof".Implementing the tap-offsTap-offs are required for different amperages depending on the sizeand type of consumersinvolved. These are implemented by means of plug-in tap-off units from 80 to 630 A orbolt-on tap-off unitsfrom 800 to 1250 A.Planning with SIVACON 8 PS162 Planning Manual, 10/2007, A5E01541101-01

Planning with LRC6.2 System componentsThanks to its cast epoxy enclosure with high IP68 degree of protection and high short-circuitrating, the LR system can provide an assurance of reliable power transmission even underthe harshest ambient conditions. It is entirely resistant to environmental factors such as airhumidity and corrosive or salty atmospheres.The compact system is suitable for flat, edgewise, vertical or horizontal installation as perrequirements in applications from 630 A to 6300 A.

Fusesand circuit-breakers are available for use as protective devices. With the selection of theseprotective devices the level of the expected short-circuit currents, selectivity requirements oroperating and signalling functions are also factors for consideration.Planning with SIVACON 8 PS236 Planning Manual, 10/2007, A5E01541101-01

Further information about planning7.1 Dimensioning and selectionWhen you decide on your short-circuit protection via fuses and circuit-breakers you must notexceed the specified short-circuit ratings of the busbar trunking systems. It depends on thelevel of expected short-circuit current, whether a current limiting protective device is requiredand what short-circuit breaking capacity the protective device must have.An overview of the circuit-breakers which are able to provide short-circuit and overloadprotection (400 V and 50 Hz) for the corresponding busbar system appears in the tablebelow.The following applies:I"k ≤ Icc ≤ IcuI''kIccIcu= anticipated short-circuit current at installation location= rated conditional short-circuit current of the trunking run= rated short-circuit breaking capacity of the circuit-breakerRated current [A] Busbar systems 1)Breaker type/MarketEuropeAsia/Middle East/South EastIcu up to 65 kAIcu 100 kA160 BD2A/BD2C 3VL 3VT 3VL250 BD2A/BD2C 3VL 3VT 3VL315 BD2A/BD2C 3VL 3VT 3VL400 BD2A/BD2C 3VL 3VT 3VL500 BD2A/BD2C 3VL 3VT 3VL630 BD2A/BD2C 3VL 3VL 3VL800 BD2A/BD2C 3WL 3WT 3WL1000 BD2A/BD2C 3WL 3WT 3WL1100 LDA 3WL 3WT 3WL1250 BD2A/BD2C, LDA, LXA/LXC 3WL 3WT 3WL1350 LRC 3WL 3WT 3WL1400 LXC 3WL 3WT 3WL1550 LRC 3WL 3WT 3WL1600 LDA/LDC 3WL 3WT 3WL1700 LRC 3WL 3WT 3WL2000 LDA/LDC 3WL 3WT 3WL2500 LDA 3WL 3WT 3WL2800 LDC 3WL 3WT 3WL3000 LDA 3WL 3WT 3WL3150 LRC 3WL 3WT 3WL3200 LXA/LXC 3WL 3WT 3WL3400 LDC 3WL 3WL 3WL3700 LDA 3WL 3WL 3WL4000 LDA 3WL 3WL 3WL4400 LDC 3WL 3WL 3WL4500 LXA 3WL 3WL 3WL5000 LDC 3WL 3WL 3WL6300 LRC 3WL 3WL 3WLPlanning with SIVACON 8 PSPlanning Manual, 10/2007, A5E01541101-01 237

Further information about planning7.1 Dimensioning and selectionThe tripping characteristic of the protective device must be selected as appropriate for theshort-circuit rating of the busbar system, the type of system, the type and number of loads,as well as in line with country-specific regulations and type series. We recommend using adimensioning program such as SIMARIS design to assist you in making this selection.7.1.3 Loop impedanceAs the level of loop impedance is decisive as regards the magnitude of the single-poleshort-circuit current, DIN VDE 0100-610 prescribes that loop impedance must be determinedbetween:● Phasel conductor and protective conductor or● Phase conductor and PEN conductorThe value can be determined by means of:● Measurements taken using measuring instruments● Calculation● Simulating the network in the network modelImpedance values for the BD2A/BD2C, LDA/LDC, LXA/LXC and LRC busbar trunkingsystems are listed in the "Technical data" section; these can be used to calculate the loopimpedances of a busbar system forming part of the total loop impedance.The minimum anticipated single-pole short-circuit current can be calculated easily based onthe loop impedance of the entire busbar trunking system.c = voltage factor 0.95UnZk= voltage between phase conductors= short-circuit impedanceCalculating the loop impedance of all contributory equipment in a system (incoming powersupply, transformers, distribution boards, cable runs, etc.) takes a great deal of time andeffort. In this regard, planning time and effort can be reduced significantly by using adimensioning program such as SIMARIS design which stores the necessary data for mostcommon electrical equipment in a database.Planning with SIVACON 8 PS238 Planning Manual, 10/2007, A5E01541101-01

DIN VDE 0100-560 relatingto buildings and structures for public use and DIN VDE 0100-710 (previously DIN VDE 0107)relating to medical locations specify that the electrical installations in such buildings mustmaintain functional endurance for specific lengths of time even in the event of a fire. Thisrequirement affects the following equipment in particular:● Fire alarm systems● Systems for alerting and providing instructions to visitors and employees● Emergency lighting● Passenger lifts with evacuation circuits that assure functional performance for at least30 minutes in the incoming cable area under full fire conditions● Water pressure boosting systems for the supply of extinguishing water● Ventilating systems of safety stairwells, fire department lifts and machine rooms wherefunctioning must be guaranteed for at least 90 minutesIn order to be able to offer the functional endurance required under the terms of thelegislation for busbar trunking systems, we have for example (in some cases workingtogether with Promat) had the BD2A/BD2C, LDA/LDC, LXA/LXC and LRC busbar trunkingsystems tested successfully at the Materials Testing Institute at Brunswick in Germany.During fire testing the busbar trunking systems concerned (housed in Promatect platecasings of varying thicknesses) were subjected to an external fire load in compliance withthe standard temperature curve (STC) in order to evaluate functional endurance toDIN 4102-12.

Further information about planning7.6 Magnetic fields7.6 Magnetic fieldsGeneral informationDue to their physical characteristics, busbars designed for power distribution andtransmission generate pulsating electromagnetic fields in their vicinity with a fundamentalfrequency of 50 Hz. These magnetic fields can impair the ability of sensitive equipment suchas computers or metering instruments to function in full working order.LimitsEMC directives and the associated standards do not set out requirements orrecommendations for the planning of busbar trunking systems. DIN VDE 0100-710 can beconsulted in relation to busbar trunking systems used in hospitals.DIN VDE 0100-710 defines limits for line frequency magnetic fields in hospitals. Forexample, at 50 Hz, the magnetic induction around a patient's bed must not exceed thefollowing values:B= 2 x 10 -7 tesla for EEGB= 4 x 10 -7 tesla for ECGThe limit for inductive interference between multi-core cables and lines in a high voltageinstallation (conductor cross section > 185 mm 2 ) and the patient beds to be protected issignificantly undershot if the minimum clearance of 9 m recommended in DIN VDE 0100-710is complied with.When using busbars, this clearance can generally be reduced, since the busbar systems aredesigned to effectively reduce the magnetic interference fields in the local vicinity.Magnetic field measurementsHowever, in order to facilitate evaluation of the busbars to be used, extensive magnetic fieldmeasurements have been taken in accordance with EN 60439-2. The magnetic fieldemissions of the busbar systems were measured on a straight trunking run 9.0 m long. Withthe busbars under a balanced rated current load, the magnetic fields were measures in eightdirections at intervals of 0.1 m and up to a clearance of 1 m.Figure 7-9Coordinate system for magnetic field measurementPlanning with SIVACON 8 PS262 Planning Manual, 10/2007, A5E01541101-01

Further information about planning7.7 Sprinkler test7.7 Sprinkler testGeneral informationSprinkler systems are used for fire prevention and protection in buildings and industrialfacilities. Sprinkler systems are automatic fire extinguishing systems. They are designed todetect the outbreak of fire at an early stage and extinguish it as quickly as possible. Onceactivated for the purpose of extinguishing fire, such systems usually run for at least30 minutes.The BD2A/BD2C, LDA/LDC and LXA/LXC busbar trunking systems underwent sprinklertesting. In the absence of a binding standard, the tests were carried out based on a teststructure reflecting practical application (see diagram).Test resultsBD2A/BD2C and LXA/LXCAll mounting positions of the BD2A/BD2C and LXA/LXC busbar trunking systems weretested for water resistance in IP54 degree of protection on the basis of the national riskprevention guidelines for sprinkler systems issued in Germany. Insulation resistancemeasurements were taken before and after the 90-minute sprinkling period and a highvoltagetest was carried out in accordance with EN 60439-2. The equipment passed the test,proving that the busbar system can be put back into operation immediately and without delayonce the sprinkler system has run its course.LDA/LDCThe LD busbar system with IP34 degree of protection and the associated tap-off units withIP54 protection were sprinkled with both horizontal and vertical trunking runs with a 3/4"umbrella sprinkler and a 1/2" flat spray sprinkler at a water pressure of 6 bar. In order to beable to assess electrical performance during testing, insulation resistance measurementswere taken during the course of the test. No operational failures occurred.Even when subject to extreme water loads such as those associated with sprinkler systems,the LDA/LDC busbar system is able to remain in full working order. This operational reliabilityis made possible on the one hand by the generous creepages and clearances and on theother by the fact that water can drain away unhindered.Planning with SIVACON 8 PSPlanning Manual, 10/2007, A5E01541101-01 267

GlossaryAThe manufacturers of low-voltage switchgear and controlgear assemblies specify ratedvalues in compliance with DIN EN 60439-1. These rated values apply to specified operatingconditions and characterise the suitability of a switchgear assembly. The rated values mustalways be referred to when combining equipment or configuring switchgear and controlgearassemblies.Rated short-time withstand current (I cw ) DIN EN 60439-1; 4.3As the rms value of the short-circuit current, the rated short-time withstand currentcharacterises the thermal strength of a switchgear and controlgear assembly circuit under atransient load. The rated short-time withstand current is normally determined for a duration of1 s; deviating time values must be specified. The rated short-time withstand current isspecified for the trunking and/or main busbars of a switchgear and controlgear assembly.Rated peak withstand current (I pk ) DIN EN 60439-1; 4.4As the peak value of the impulse current, the rated peak withstand current characterises thedynamic strength of a circuit in a switchgear and controlgear assembly.
