Circuit br
onitoring
The relay incorporates circuit breaker state monitoring, giving an indication of the position of
2.6.1
e set to monitor normally open (52a) and normally closed (52b) auxiliary
aker. Under healthy conditions, these contacts will be in opposite
eaker state m
the circuit breaker, or, if the state is unknown, an alarm is raised.

conditions:
−
Auxiliary contacts / wiring defective
−
Circuit Breaker (CB) is defective
−
