Function description
Breaker close/trip circuit monitoring
Functionality
The trip circuit supervision function TCSSCBR is designed to supervise the control circuit
of the circuit breaker. The trip circuit supervision generates a current of approximately 1
mA through the supervised control circuit. The validity supervision of a control circuit is
provided for power output contacts T1, T2 and T3.
The function picks up and trips when TCSSCBR detects a trip circuit failure. The trip time
characteristic for the function is of definite time (DT) type. The function trips after a
predefined operating time and resets when the fault disappears.
