LV power air circuit breakers
and switch-disconnectors
Masterpact NW

Things
never will be
same
the
The original Masterpact has
set a new standard for power
circuit breakers around the
world. Over the years, other
major manufacturers have
tried to keep up by developing
products incorporating
Masterpact’s most innovative
features, including the
breaking principle, modular
design and the use of
composite materials.
Today, Schneider Electric continues to
innovate with the new Merlin Gerin
Masterpact NW.
In addition to the traditional features of
power circuit breakers (withdrawability,
discrimination and low maintenance),
Masterpact now offers built-in
communications and metering
functions, all in optimised frame sizes.
Masterpact NW incorporates the latest
technology to enhance both
performance and safety. Easy to install,
with user-friendly, intuitive operation
and environment-friendly design, it is,
quite simply, the ultimate ACB.

New Masterpact,
new levels of performance
Four performance levels
H1 - for industrial sites with high short-circuit levels or installations with
two parallel-connected transformers.
H2 - high-performance for heavy industry where very high short-circuits
can occur.
H3 - for incoming devices supplying critical applications requiring both
high performance and a high level of discrimination.
L1 - for high current-limiting capability and discrimination levels, as yet,
unequalled by any other circuit breaker of its type. Intended for the
protection of cable-type feeders or to raise the performance level of a
switchboard when the transformer power rating is increased.
Integration in a communications
network
Masterpact can be integrated in a general supervision system to optimise
installation operation and maintenance. The communication architecture
is open, and may be upgraded for interfacing with any protocol.
Switch-disconnector versions
The switch-disconnectors are derived directly from the circuit breakers
and offer the same features and performance levels.
1000 V and 400 Hz
distribution systems
The Masterpact range
can be used on 1000V
installations (mining
industry) and 400Hz
systems (aeronautics,
computer centres).

Optimised
volumes
Practical installation
solutions
The new range improves upon all the
installation solutions which have already made
Masterpact a success. It has been designed to
standardise switchboards, optimise volumes
and simplify installation:
■ Incoming connection to top or bottom
terminals.
■ No safety clearance required.
■ Connection:
■ Horizontal or vertical rear connection.
■ Front connection with minimum extra space.
■ Mixed front and rear connections.
■ 115 mm pole pitch on all versions.
■ No derating up to 55° C and 4000A.
Optimised volumes
Up to 4000A, Masterpact NW circuit breakers
are all the same size, the same size as the
previous M32 frame.
From 4000A to 6300A, there is just one size,
which is considerably smaller than before.
Retrofit solutions
Special connections are available to replace a
fixed or drawout Masterpact M08 to M32 with a
Masterpact NW, without modifying the busbars
6

Ease of
installation
With optimised sizes, the Masterpact NW range
simplifies the design of switchboards and selection/
installation of devices:
■ Three connection layouts for Masterpact NW:
■ One from 800 to 3200A (NW08 - NW32).
■ One for 4000 A (NW40a).
■ One 4000 to 6300A (NW40b - NW63).
■ Identical auxiliary connection terminals from 800
to 6300A (Masterpact NW).
■ Front connections do not impact on the depth
of the device.
■ Rear connections are converted from
vertical or horizontal busbars, simply by
turning the connectors through 90°.

Innovation
Greater dependability…
Filtered breaking
The patented new design of the arc chutes includes stainless-steel filters.
The chutes absorb the energy released during breaking, thus limiting the
stresses exerted on the installation. They filter and cool the gases
produced, reducing the external effects of short circuit clearance.
Automatic unlatching(H3 and L1)
The automatic unlatching of the circuit breaker operating mechanism for
high short-circuits extends performance up to 150kA. It produces ultrafast
tripping for all short-circuits higher than 37 kA (L1) and 65 kA (H3).
For lower short-circuits, the system does not react so that the control unit
can provide total discrimination with downstream devices.
Filtered breaking
More intelligent trip units…
Today, with the high speed of calculation, the small size of memory and
advances in miniaturisation, trip units have become circuit breaker control
units offering increasingly powerful functions. They accurately measure
system parameters, instantly calculate values, store data, log events,
signal alarms, communicate, take action, etc. The new Masterpact range
equipped with Micrologic control units, constitute both an extremely
reliable protective device and an accurate measurement instrument.
User friendly…
Intuitive use…
Micrologic control units are equipped with a digital LCD display used in
conjunction with simple navigation buttons. Users can directly access
parameters and settings. Navigation between screens is intuitive and the
immediate display of values greatly simplifies settings. Text is displayed in
the desired language.
Navigation buttons on a Micrologic P
control unit.
… backed by incomparable security
Protection functions are separate from the measurement functions and
are managed by an ASIC electronic component. This independence
guarantees immunity from conducted or radiated disturbances and
ensures a high degree of reliability.
A patented “double setting” system for protection functions establishes:
■ A maximum threshold set using the control-unit dials.
■ Fine adjustments via the keypad or remotely.
The fine adjustments for thresholds (to within one ampere) and tripping
delays (to within a fraction of a second) are displayed directly on the
screen.
The control unit cover can be lead-sealed to prevent uncontrolled access
to the dials and protect the settings.

Ready for
the future
Compliance with
environmental
requirements
Schneider Electric fully take into account
environmental requirements, starting right from
the design phase of every product, through to
the end of its service life:
■ The materials used for Masterpact are not
dangerous to the environment.
■
■
■
■
The production facilities are non-polluting in
compliance with the ISO 14001 standard.
Filtered breaking eliminates pollution in the
switchboard.
The energy dissipated per pole is low,
making energy losses insignificant.
The materials are marked to facilitate sorting
for recycling at the end of product service
life.
Simple upgrading of
installations
Installations changes and power level increases
normally mean new equipment and
switchboards extensions:
■ All control units are interchangeable.
■
■
Communication with a supervision system is
an option that may be added at any time.
A reserve chassis can be pre-addressed so
that system parameters do not have to be
modified when a drawout device is installed
at a later date.

All Masterpact circuit breakers can be
equipped with a Micrologic control unit.
Control units are designed to protect Power
circuits and loads. Alarms may be
programmed for remote indications.
Measurements of current, voltage,
frequency, power and power quality
optimise continuity of service and energy
management.
Dependability
The use of an ASIC electronic component for protection functions in all Micrologic

Protection settings........................................................ +
The adjustable protection functions are identical to those of Micrologic A
(overloads, short-circuits, earth-fault and earth-leakage protection).
Double setting
Within the range determined by the adjustment dial, fine adjustment of thresholds
(to within one ampere) and time delays (to within one second) is possible with the
keypad or remotely via the COM option.
IDMTL setting
Coordination with fuse-type or medium-voltage protection systems is optimised by
adjusting the slope of the overload-protection curve.
Neutral protection
On three-pole circuit breakers, neutral protection may be set using the keypad or
remotely using the COM option, to one of four positions: neutral unprotected (4P
3t), neutral protection at 0.5 In (4P 3t + N/2), neutral protection at In (4P 4t) and
neutral protection at 2 In (4P 3t + 2N). Neutral protection at 2 In is used when the
neutral conductor is twice the size of the phase conductors (major load imbalance,
high level of third order harmonics).
On four-pole circuit breakers, neutral protection may be set using a three-position
switch or the keypad: neutral unprotected (4P 3t), neutral protection at 0.5 In (4P 3t
+ N/2), neutral protection at In (4P 4t). IDMTL protection settings offer three phase
protection only.

Programmable alarms and other protection ......................
Depending on the set thresholds and time delays, the Micrologic P control unit
monitors currents and voltage, power, frequency and the phase sequence. Each
threshold overrun is signalled remotely via the COM option and may be combined
with tripping (protection) or an indication carried out by an optional M2C or M6C
programmable contact (alarm), or both (protection and alarm).
12 14
15
Load shedding and reconnection........................................
Load shedding and reconnection parameters may be set according to the power or
the current flowing through the circuit breaker. Load shedding is carried out by a
supervisor via the COM option or by an M2C or M6C programmable contact.

Measurements .......................................................................
The Micrologic P control unit calculates (in real time) all the electrical values (V, A,
W, VAR, VA, Wh, VARh, VAh, Hz), power factors and crest factors.
The Micrologic P control unit also calculates demand current and demand power
over an adjustable time period.
In the event of tripping on a fault, the interrupted current is stored. The optional
external power supply makes it possible to display the value with the circuit breaker
open.
Histories and maintenance indicators ................................
The last ten trips and alarms are recorded in two separate history files.
Maintenance indications (contact wear, operation cycles, etc.) are recorded for
local access.
1 Long-time current setting and tripping delay.
2 Overload signal (LED).
3 Short-time pick-up and tripping delay.

Indication option via programmable contacts
The M2C (two contacts) and M6C (six contacts) auxiliary contacts may be used to
signal threshold overruns or status changes. They can be programmed using the
keypad on the Micrologic P control unit or remotely using the COM option.
Communication option (COM)
The communication option may be used to:
c Remotely read and set parameters for the protection functions.
c Transmit all the calculated indicators and measurements.
c Signal the causes of tripping and alarms.
c Consult the history files and the maintenance-indicator register.
An event log and a maintenance register, stored in control-unit memory but not
available locally, may be accessed in addition via the COM option.
Note.
Micrologic P control units come with a non-transparent

Additional technical characteristics
Setting the display language
System messages may be displayed in six different languages. The desired language is
selected via the keypad.
Protection functions
All current-based protection functions require no auxiliary source. Voltage-based
protection functions are connected to AC power via a voltage measurement input built
into the circuit breaker.
Measurement functions
Measurement functions are independent of the protection functions.
The high-accuracy measurement module operates independently of the protection
module, while remaining synchronised with protection events.
Measurement-calculation mode
c Measurement functions are based on the new “zero blind time” concept which
continuously measures signals at a high sampling rate, rather than the traditional
“blind window” process. This method ensures accurate energy calculations even for
highly variable loads (welding machines, robots, etc.).
c Energies are calculated on the basis of the instantaneous power values, in two ways:
v The traditional mode where only positive (consumed) energies are considered
v The signed mode where the positive (consumed) and negative (supplied) energies
are considered separately.
Accuracy of measurements (including sensors)
c Voltage (V) 1%.
c Current (A) 1.5%.
c Frequency (Hz) 0.1 Hz.
c Power (W) and energy (Wh) 2.5%.
Stored information
The fine setting adjustments, the last 100 events and the maintenance register remain in
the control-unit memory even when power is lost.
Time-stamping
Time-stamping is activated only if an external power supply module is present (max. drift
of 1 hour per year).
Reset
An individual reset, via the keypad or via COM, acts on alarms, minimum and maximum
data, peak values, the counters and indicators.

Communication
Communication architecture
The (COM) communication option is
required for integration of the circuit
breaker or switch-disconnector in a
supervision system.
Masterpact uses Modbus or Jbus
communications protocol for full
compatibility with SMS PowerLogic
(electrical network) management systems.
An external gateway is available for
communication over ethernet networks.
COM communication option
For fixed devices, the COM option comprises of a communication module installed
within the device and supplied by a set of sensors (OF, SDE ,PF and CH microcontacts)
kit for connection to XF and MX communicating voltage releases.
For drawout devices, the COM option comprises of:
c A communication module within in the device and supplied by a set of
auxilliaries (OF, SDE, PF and CH micro-contacts) and/or a kit for connection to
XF and MX communicating voltage releases.
c A communication module installed on the chassis and supplied by a set of
sensors (CE, CD and CT contacts).
Each installed device has an address that is assigned via the keypad of the control
unit (Modbus) or remotely (Batibus). The address of a drawout device is assigned
to the chassis which maintains the same address if the device is replaced.
Status indication by the COM option is independent of the auxiliary indication
contacts. These contacts remain available for conventional uses.
“Device” communication module
This module is independent of the control unit. Installed in the device, behind the
control unit, it receives and transmits information on the communication network.
An infra-red link transmits data between the control unit and the communication
module.
Consumption: 100 mA.
“Chassis” communication module
Installed on the chassis, this module makes it possible to address the chassis and
to maintain the address when the circuit breaker is in the disconnected position.
Consumption: 100 mA.
XF and MX communicating voltage releases
The XF and MX communicating voltage releases are equipped for connection to
the “device” communication module.
The remote-tripping function (second MX or MN) is independent of the
communication option.

Functions
and characteristics
Communication
Masterpact in a communication
network
Devices
Circuit breakers equipped with Micrologic control units may be connected to either
a Digipact or Modbus communication bus. The information made available
depends on the type of Micrologic control unit (A, P or H) and on the type of
communication bus (Digipact or Modbus).
Switch-disconnectors may be connected exclusively to the Digipact communication
bus.
Communication bus
Digipact bus
The Digipact bus is the internal bus of the low-voltage switchboard in which the
Digipact communicating devices are installed (Masterpact with Digipact COM,
PM150, SC150, UA150, etc.). This bus must be equipped with a DC150 data
concentrator (see the Powerlogic System catalogue).
Addresses
Addressing is carried out by the DC150 data concentrator.
Number of devices
The maximum number of devices that may be connected to the Digipact bus is
calculated in terms of “communication points”. These points correspond to the
amount of traffic the bus can handle. The total number of points for the various
devices connected to a single bus must not exceed 100.
If the required devices represent more than 100 points, add a second Digipact
internal bus.
Communicating device Number of points
DC150 data concentrator 4
Micrologic + Digipact COM 4
PM150 4
SC150 4
UA150 4
Length of bus
The maximum recommended length for the Digipact internal bus is 200 meters.
Bus power source
Power is supplied by the DC150 data concentrator (24 V)..
30

Modbus bus
The Modbus RS485 (JBus) system is an open bus on which communicating
Modbus devices (Masterpact with Modbus COM, PM300, Sepam, Vigilohm, etc.)
are installed. All types of PLCs and microcomputers may be connected to the bus.
Addresses
The software layer of the Modbus protocol can manage up to 255 addresses (1 to 255).
The “device” communication module comprises three addresses linked to:
n circuit-breaker manager;
n measurement manager;
n protection manager.
The “chassis” communication module comprises one address linked to:
n the chassis manager.
The division of the system into four managers secures data exchange with the
supervision system and the circuit-breaker actuators.
The manager addresses are automatically derived from the circuit-breaker address
@xx entered via the Micrologic control unit (the default address is 47).
logic addresses
@xx Circuit-breaker manager (1 to 47)
@xx + 50 Chassis manager (51 to 97)
@xx + 200 Measurement managers (201 to 247)
@xx + 100 Protection manager (101 to 147)
Number of devices
The maximum number of devices that may be connected to the Modbus bus
depends on the type of device (Masterpact with Modbus COM, PM300, Sepam,
Vigilohm, etc.), the baud rate (19200 is recommended), the volume of data
exchanged and the desired response time. The RS485 physical layer offers up to
32 connection points on the bus (1 master, 31 slaves).
A fixed device requires only one connection point (communication module on the
device).
A drawout device uses two connection points (communication modules on the
device and on the chassis).
The number must never exceed 31 fixed devices or 15 drawout devices.
Length of bus
The maximum recommended length for the Modbus bus is 1200 meters.
Bus power source
A 24 V DC power supply is required (less than 20% ripple, insulation class II).
Communication interface
The Modbus bus may be connected to the central processing device in any of
three manners:
n direct link to a PLC. The communication interface is not required if the PLC is
equipped with a Modbus port;
n direct link to a computer. The Modbus (RS485) / Serial port (RS232)

Note:
An opening order always takes priority over a closing
order.
If opening and closing orders occur simultaneously(when
in the open position), the mechanism discharges without
any movement of the main contacts. The circuit breaker
remains in the open position (OFF).
In the event of maintained opening and closing orders,
the standard mechanism provides an anti-pumping
function by maintaining the main contacts in the open
position.
After tripping or opening using the manual or electrical
controls, the closing coil must first be reset before reclosing
can take place.
When the ‘automatic reset after fault trip (RAR)’ option is
installed, it is impotant to ensure that the automatic/
remote closing system is designed to prevent Autoreclosing
under fault trip conditions.

Mechanical interlocking
Electrical interlocking of two or three
devices is used to create a remoteoperated
source-changeover system. A
mechanical interlocking system enhances
the reliability of system operation.
To ensure a continuous supply of power, certain electrical installations are
connected to two power supplies:
c A normal supply N;
c A replacement supply R which supplies the installation when source N is not
available.
A source-changeover system switches between the two supplies. The system may
include an automatic controller which manages switching according to external
conditions. A source-changeover system may comprise two or three circuit
breakers or switch-disconnectors.
Interlocking of two devices using connecting rods
The two devices must be stack mounted.
This function requires:
c An adaptation fixture on the right side of each device.
c A set of connecting rods with no-slip adjustments.
The complete interlock kit is supplied for assembly by the customer.
Maximum vertical distance between the fixing planes: 900 mm
Combinations of Masterpact Normal and Replacement devices
The two devices must both be fixed devices or drawout devices to maintain correct
alignment of the mechanisms.
Interlocking of two or three devices using cables
Using cables, the devices may be stack mounted or installed side-by-side.
Interlocking of two devices
This function requires:

Performance and
functionality
Associated automatic controllers
By combining a remote-operated sourcechangeover
system with an integrated BA
or UA automatic controller, it is possible to
automatically control supply transfer
according to user-selected sequences.
These controllers can be used on
source-changeover systems comprising 2
circuit breakers.
For source-changeover systems
comprising 3 circuit breakers, the
automatic control diagram must be
prepared by the installer as a complement
to to diagrams provided in the “electrical
diagrams” section of this catalogue.

(1) The controller is powered by the ACP auxiliaries control plate. The same voltage
must be used for the ACP plate, the IVE unit and the circuit breaker motor mechanisms.
If this voltage is the same as the source voltage, then the “Normal” and “Replacement”
sources can be used directly for the power supply. If not, a BC type or equivalent
isolation transformer must be used.

None of the control-unit protection functions require an auxiliary source. However, the 24 V DC external power-supply (AD module) is
required for certain operating configurations as indicated in the table below.

(2) except for Micrologic A control units.
(3) time setting is manual and can be carried out automatically by the supervisor via the communications bus.
The communications bus requires its own 24 V DC power source (E1, E2). This source
is not the same as the 24 V DC external power-supply module (F1-, F2+).
The BAT battery module, mounted in series upstream of the AD module, ensures an
uninterrupted supply of power if the AD module power supply fails.
The voltage measurement inputs are standard equipment on the downstream
connectors of the circuit breaker.
External connections are possible using the PTE external voltage measurement input
option. With this option, the internal voltage measurement inputs are disconnected and
terminals VN, V1 and V2 are connected only to the control unit (Micrologic P and H only).
The PTE option is required for voltages less than 100 V and greater than 690 V (in which
case a voltage transformer is required). For three-pole devices, the system is supplied
with terminal VN connected only to the control unit (Micrologic P and H).
When the PTE option is implemented, the voltage measurement input must be protected
against short-circuits. Installed as close as possible to the busbars, this protection
function is ensured by a P25M circuit breaker (1 A rating) with an auxiliary contact (cat.
no. 21104 and 21117). This voltage measurement input is reserved exclusively for the
control unit and must not ever be used to supply other circuits outside the switchboard.

A pilot wire interconnects a number of circuit breakers equipped with Micrologic A/P/H
control units, as illustrated in the diagram above.
The control unit detecting a fault sends a signal upstream and checks for a signal
arriving from downstream. If there is a signal from downstream, the circuit breaker
remains closed for the full duration of its tripping delay. If there is no signal from
downstream, the circuit breaker opens immediately, whatever the tripping-delay setting.
Fault 1.
Only circuit breaker A detects the fault. Because it receives no signal from downstream,
it immediately opens in spite of its tripping delay set to 0.3.
Fault 2.
Circuit breakers A and B detect the fault. Circuit breaker A receives a signal from B and
remains closed for the full duration of its tripping delay set to 0.3. Circuit breaker B does
not receive a signal from downstream and opens immediately, in spite of its tripping
delay set to 0.2.

recommendations
Installation in switchboard
Mounting position
Power supply
Masterpact devices can be supplied either from the top or from the bottom without
reduction in performance.
Mounting the circuit-breaker
It is important to distribute the weight of the device uniformily over a rigid mounting
surface such as rails or a base plate.
This mounting plane should be perfectly flat (tolerance on support flatness: 2 mm).
This eliminates any risk of deformation which could interfere with correct operation
of the circuit breaker.
Masterpact devices can also be mounted on a vertical plane by the use of brackets
(optional extra).
Mounting on rails.

Extend the circuit breaker terminals using short
bars designed and installed according to the
recommendations for bar-type power connections:
For a single cable, use solution B opposite.
For multiple cables, use solution C opposite.
In all cases, follow the general rules for
connections to busbars:
v Position the cable lugs before inserting the bolts

Busbars connections
The busbars should be suitably adjusted to ensure
that the connection points are positioned on the
terminals before the bolts are inserted (B)
The connections are held by the support which is
solidly fixed to the framework of the switchboard, such
that the circuit breaker terminals do not have to
support its weight (C).

Electrodynamic stresses
The first busbar support or spacer should be situated within a maximum distance
from the connection point of the breaker (see table below). This distance must be
respected so that the connection can withstand the electrodynamic stresses
between phases in the event of a short circuit.

Clamping
Correct clamping of busbars depends amongst other things, on the tightening
torques used for the nuts and bolts. Over-tightening may have the same
consequences as under-tightening.
For connecting busbars to the circuit breaker, the tightening torques to be used are
shown in the table below.
These values are for use with copper busbars and steel nuts and bolts, class 8.8.
The same torques can be used with AGS-T52 quality aluminium bars (French
standard NFA 02-104 or American National Standard H-35-1).
