Breaker close/trip circuit monitoring TCSSCBR

Identification

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 invalidity of a control circuit is detected by using
a dedicated output contact that contains the supervision functionality.
The function operates after a predefined operating time and resets when the fault
disappears.
