Planning with SIVACON 8 PS - Siemens

Planning with LDA/LDC4.2 System componentsThe following certificates or declarations of conformity must accompany the offer:● DIN ISO 9001 QA certification● Proof of sprinkler testing● Proof of absence of halogen● Proof of prevention of propagation of an arcing fault● Proof that the system is maintenance-freeFollowing the general information, a precisedescription of the system based on the technicalrequirements should be provided as follows:Technical data for LDA/LDC busbar trunking systemsRated current _________ 1)Degree of protectionIP34/IP54Mounting position Horizontal/vertical 2)Rated insulation voltage1000 VAC/1200 VDCRated operating voltage1000 VACRated frequency16 2/3 – 60 HzRated peak withstand current Ipk _________ 1)Rated short-time withstand current Icw (1 s) _________ 1)Conductor material Al/Cu 2)No. of conductorsL1 – L3 and PEN (4 bars/4-pole)L1 – L3 and ½ PEN (7 bars/4-pole)L1 – L3 and PEN (8 bars/4-pole)L1 – L3, N, PE (5 bars/5-pole)L1 – L3, ½ N, ½ PE (8 bars/5-pole)L1 – L3, N, ½ PE (9 bars/5-pole)Fire load without tap-off points _________ 1)Enclosure dimensions LDA1 to LDC3 180 x 180 mm 2)LDA4 to LDC8 240 x 180 mm 2)1) Enter data for selected systems. 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
