Functions
and characteristics
Indication contacts
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 P and H
control units.
ON/OFF indication contacts (OF)
b rotary type changeover contacts directly driven by the mechanism for
Masterpact UR. 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:
b a red mechanical fault indicator (reset)
b one changeover contact (SDE).
Following tripping, the mechanical indicator must be reset before the circuit breaker
may be closed.

“Fault-trip” indication contacts (SD UR)
Circuit-breaker tripping due to a Thomson (TEC) fault is signalled by a change over
contact (SDUR).
This contact is located inside the "UR Power" module.
Note: this contact is a non Latching contact. To keep the indication, it is necessay to connect on
external relay.
