Function description
Breaker close/trip circuit monitoring
8.1.2

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 trip circuit supervision operates after a settable definite operating time and resets after a settable
definite time when the fault disappears.
