Functions
and characteristics
Electrical interlocking of two or three devices is used to
create a remote-operated source-changeover system.
A basic mechanical interlocking system enhances the
reliability of system operation.
Interlocking of two Compact NS100 to 630 devices using a base
plate
A base plate designed for two Compact circuit breakers can be installed horizontally
or vertically on a mounting rail. Interlocking is carried out on the base plate by a
mechanism located behind the breakers. Access to the circuit breaker controls and
trip units is conserved. Circuit breakers must be xed or plug-in versions, with or
without earth-leakage protection or measurement modules. The base plate and the
circuit breakers are supplied separately.
base plate for Compact NS100 to 250 devices
This base plate is intended for two Compact NS100 to 250 devices.
base plate for Compact NS400 to 630 devices
This base plate is intended for two Compact NS400 to 630 devices. It may also be
used, without any modications, to interlock a xed Compact NS100 to 250 with a
Compact NS400 or 630 device.
An adapter kit is required for plug-in versions of the Compact NS100 to 250 devices.
Compact NS100 to 250 devices, in both xed and plug-in versions, may be equipped
with spreaders.

Interlocking of two Compact NS630b to 1600 or two Masterpact
NT and NW devices using connecting rods
The two devices must be mounted one above the other (either 2 xed or 2
withdrawable/drawout devices).
Combinations are possible between Compact NS630b to NS1600 devices and
between Masterpact NT and Masterpact NW devices.
Installation
This function requires:
an adaptation xture on the right side of each circuit breaker or switch-
disconnector
a set of connecting rods with no-slip adjustments.
The adaptation xtures, connecting rods and circuit breakers or switch-
disconnectors are supplied separately, ready for assembly by the customer.
The maximum vertical distance between the xing planes is 900 mm.
