Compact NS100 to 630 (cont.)
Remote tripping
MX or MN voltage release
A-100
MX or MN voltage releases are used to trip the circuit breaker.
MN undervoltage release
This release trips the circuit breaker when the control voltage drops below a
tripping threshold:
b tripping threshold between 0.35 and 0.7 times the rated voltage
b circuit breaker closing is possible if the voltage exceeds 0.85 times the rated
voltage.
For a lower value, circuit breaker closing cannot be guaranteed.
Circuit breaker tripping by an MN release meets the requirements of standard
IEC 60947-2.
Time-delay unit for an MN release
Eliminates nuisance tripping due to transient voltage dips lasting 200 ms.
It is used in conjunction with:
b a 250 V DC MN release, control voltage 220/240 V AC
b a 48 V DC MN release, control voltage 48 V AC.
MX shunt release
Trips the circuit breaker when the control voltage rises above 0.7 x Un.
Control signals can be of the impulse type (u 20 ms) or maintained.
Operation
When the circuit breaker has been tripped by an MN or MX release, it must be
reset locally.
MN or MX tripping takes priority over manual closing.
In the presence of a standing trip order, closing of the contacts, even temporary,
is not possible.
Mechanical characteristics
b endurance is equal to 50 % of the mechanical endurance of the circuit breaker
b the releases clip in behind the front cover
b connection using wires up to 1.5 mm2, to integrated terminal blocks.
Electrical characteristics
b consumption:
v pick-up (MX): < 10 VA
v seal-in (MN and MNR): < 5 VA.
b response time: < 50 ms.
047313
Motor-mechanism module
When equipped with a motor-mechanism module, Compact NS circuit breakers
feature very high mechanical endurance as well as easy and sure operation:
b all circuit-breaker indications and information remain visible and accessible,
including trip-unit settings and indications
b suitability for isolation is maintained and padlocking remains possible
b double insulation of the front face.
Applications
b local motor-driven operation, centralised operation, automatic distribution control
b normal/standby source changeover or switching to a replacement source to
optimise energy costs
b load shedding and reconnection to optimise energy costs
b synchrocoupling.
Automatic operation
b circuit-breaker ON and OFF controlled by two impulse-type or maintained control
signals
b automatic spring charging following voluntary tripping (by MN or MX),
with standard wiring
b mandatory manual reset following tripping due to an electrical fault.
Manual operation
b transfer to manual mode using a switch (9) with possibility of remote mode
indication
b circuit-breaker ON and OFF controlled by 2 pushbuttons
b recharging of stored-energy system by pumping the lever 9 times
b padlocking in OFF position.
Installation and connection
All installation (fixed, plug-in/withdrawable) and connection possibilities are
maintained.
Motor-mechanism module connections are made behind its front cover to
integrated terminals, for cables up to 2.5 mm2.
Accessories
b keylock for locking in OFF position
b operations counter for the Compact NS400 and NS630, indicating the number of
ON and OFF cycles. The counter must be installed on the front of the motormechanism module.

Instantaneous voltage releases (MN)
The MN release instantaneously opens the circuit breaker when its supply voltage
drops to a value between 35 % and 70 % of its rated voltage. If there is no supply
on the release, it is impossible to close the circuit breaker, either manually or
electrically. Any attempt to close the circuit breaker has no effect on the main
contacts. Circuit-breaker closing is enabled again when the supply voltage of the
release returns to 85 % of its rated value.

breaker. A continuous supply of power to the 2nd MX locks the circuit breaker in
the OFF position.

Instantaneous voltage releases (MN)
The MN release instantaneously opens the circuit breaker when its supply voltage
drops to a value between 35 % and 70 % of its rated voltage. If there is no supply
on the release, it is impossible to close the circuit breaker, either manually or
electrically. Any attempt to close the circuit breaker has no effect on the main
contacts. Circuit-breaker closing is enabled again when the supply voltage of the
release returns to 85 % of its rated value.

MN delay units
To eliminate circuit-breaker nuisance tripping during short voltage dips, operation
of the MN release can be delayed. This function is achieved by adding an external
delay unit in the MN voltage-release circuit. Two versions are available, adjustable
and non-adjustable.

Display modules
057454
Perfectly integrated in the Compact
and Masterpact ranges, Display modules
are designed for use with Micrologic control
units to provide instant and highly intuitive
access to all the information provided by
the circuit breakers, including device status,
current, voltage and power values, etc.
DMB300 and DMC300 display modules use the power and communications
capabilities of the Micrologic control units to centralise the display of electrical
values, status conditions and alarms of one or more Compact
or Compact circuit breakers.
The mounting and cabling system for the display modules ensures fast,
easy and reliable installation.
Start-up is immediate with no configuration or programming required.
Display modules are high-performance devices combining:
b simple and easy-to-read dials
b powerful and accurate digital processing.
Their small size and extensive communications capabilities make for easy and
flexible installation and operation.
