- operation of a voltage release
- operation of the “push to trip” button
- disconnection when the device is ON.
The SD contact returns to de-energised state when the circuit breaker is reset.
- SDE (fault-trip indication) indicates that the circuit breaker has tripped due to:
- an overload
- a short-circuit
- an earth fault (Vigi)
- SDV indicates that the circuit breaker has tripped due to an earth fault. It returns
de-energised state when the Vigi module is reset.
