Siemens Fault Signal Contact 1 NO+1 NC – 5ST3020

Fault signal contact (FC):

The fault signal contact (FC) signals when the miniature circuit breaker switches off automatically in the event of a fault e.g. due to overload or short circuit. If the fault signal contact is switched on, the contact position remains unchanged, when the circuit breaker is operated manually. The fault signal contact with test and reset button, allows the control circuit to be tested without switching the miniature circuit breaker. The red reset button integrated in the actuating handle shows when the miniature circuit breaker switches off automatically. The signal can be acknowledged manually by pressing the reset button

The Fault Signal Contact (FC) – e. g. 5ST3020 – switch at the same time with the main contacts of the MCB at the manual activity in “ON” – not in “OFF”. Only by overload or short-circuit of the MCB the FC switches in “OFF”.
