Fault status
When the level of residual current, detected by the toroid, is higher than
I∆n threshold, the RD3 relay causes the automatic opening of the circuit
breaker to which it is connected by means of the shunt trip.
Connection with the shunt trip when the current is activated:
The residual current protection
is not active when this circuit
breaker is switch-off
