modular system A wider range of add-on modules makes itpossible to adapt the Compact system to amaximum number of configurations.
Trip units, auxiliaries and installation andconnection accessories are the same for allmodels within each of following ranges:c Compact NS80 and NSA125/160c Compact NS100 to NS250,c Compact NS400 to NS630,
c Compact C801 to C1251.The common modules for Compact NS100to NS250 circuit breakers and switch-
disconnectors are shown opposite.The same principle applies to CompactNS400 to NS630 and Compact C801 toC1251 circuit breakers.Fewer catalogue numbers means immediateavailability of parts for all solutions.

interchangeable
trip units
Each Compact device provides differenttypes of protection depending on theassociated trip unit:
c standard protection,c protection of networks supplied bygenerators,c protection of long cables,c protection of DC networks,c protection of motor-starters,c service connection circuit breaker (forspecial subscriber contracts).
Electronic trip unit STR22SE.
On Compact NS100 to NS250 circuit
breakers, the thermal-magnetic andelectronic trip units are interchangeable andmay be rapidly fitted to the circuit breakers.
It is therefore easy to change the protection
of a given circuit following a modification inan installation.
On Compact NS400 and NS630 circuitbreakers, the electronic trip units areinterchangeable plug-in modules.Trip unit STR53UE offers a large number ofprotection settings.

Thermal-magnetic trip unit TM.
Compact NS250H.
Compact C801... 1251
Compact C1251H circuit breaker.
Electronic trip units allow perfect adaptationof the protection to each circuit in the
electrical distribution network, and, at thesame time, simplify the selection, installationand operation of the devices:c wider range of settings, so that a singletrip unit can provide several types ofprotection,c easier checking during assembly or onsite,c new functions offered by the trip unit, such
as load monitoring and local indications.

A motor mechanism can be fitted to the frontface of Compact NS100 to C1251 circuitbreakers. Remote control of the opening,closing and reset functions is then possiblevia 2 or 3 impulse or maintained signals.If necessary, the circuit breakers can still beoperated locally via the controls on the front
face.The motor mechanism modules for each
range have a common size.The motor mechanism module forCompact NS is also available incommunicating version (see Digipact
catalogue).
Vigi earth-fault protectionmodule
Vigi modules can be added to Compact NS
circuit breakers to provide earth-faultprotection. The Vigi modules fit directly onthe circuit breaker terminals.
The addition of a Vigi module has no effecton the other performance characteristics ofthe circuit breaker.

Fault indications (F) In addition to indications for standard faults(toggle, SD and SDE auxiliary switches), thisoption differentiates between the threepossible causes of tripping via three LEDs:c overload (LT);c short-circuit (ST + INST);c earth fault.
A three-LED load monitoring functionindicates 60, 70 and 80% of the LTthresholds in addition to the standard 90 and105% indications. Option F is not available
on STR45BE trip units. It requires anexternal power supply.

Communication (COM)The following information is transmitted toDigipact distribution monitoring and controlmodules: all data concerning the currentspassing through the CTs, all trip-unitsettings, including those of options T andR,load-shedding orders, fault indicationsprovided by option F and an alarm indicationwhen the internal temperature is 10C belowthe circuit breaker self-protection threshold.

Zone selective interlocking (Z)A number of circuit breakers areinterconnected one after another by a pilot-
wire. In the event of a short-time or earthfault, the control unit applies the set timedelay only if it receives a signal from adownstream circuit breaker. If not, it trips
instantaneously (tripping time as 0.1 short-time setting). In this way, the fault is clearedrapidly by the nearest circuit breaker. Thethermal stresses in the installation areminimised while maintaining time
discrimination throughout the entireinstallation.Opto-electronic outputsThe use of opto-transistors ensures totalisolation between the internal circuits of thecontrol unit and the circuits wired by theuser.
options for electronic trip units STR45/55
Earth fault protection (T)
The earth fault protection is of the residualcurrent type. The circuit breaker trips, afteran adjustable time delay th, at an adjustablethreshold In that depends on the ratedcurrent In.On request, the earth fault protection may beof the "W" type (source ground return) or ofthe neutral protection type.The thermal memory is identical to that ofthe LT protection, with a time constant of20 seconds.
For distributed neutral systems, option Trequires installation of the 4th polesensor downstream the circuit breaker.
