9.2.2
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.
