Indication contacts are available:
b
in the standard version for relay applications
b
in a low-level version for control of PLCs and
electronic circuits.
M2C and M6C contacts may be programmed via the
Micrologic E, P and H control units.
ON/OFF indication contacts OF
Two types of contacts indicate the ON or OFF position of the circuit breaker:
micro switch type changeover contacts for Masterpact NT
b
b
rotary type changeover contacts directly driven by the mechanism for Masterpact
b
b
NW. These contacts trip when the minimum isolation distance between the main
circuit-breaker contacts is reached.

“Fault-trip” indication contacts SDE
Circuit-breaker tripping due to a fault is signalled by:
a red mechanical fault indicator (reset)
b
b
one changeover contact SDE.

Following tripping, the mechanical indicator must be reset before the circuit breaker
may be closed. One SDE is supplied as standard. An optimal SDE may be added.
This latter is incompatible with the electrical reset after fault-trip option (RES).

Combined “connected/closed” contacts EF
The contact combines the “device connected” and the “device closed” information to
produce the “circuit closed” information. Supplied as an option for Masterpact NW, it
is mounted in place of the connector of an additional OF contact.
