Summary:The invention concerns a fault-current protective switch including a switch latch with a magnetic tripping device. The invention calls for the combination of working-current and quiescent-current triggering of the switch latch, as well as the provision of a self-monitoring circuit. This embodiment of the fault-current protection circuit has an intrinsically safe self-monitoring circuit which triggers the switch latch both when a fault current occurs and when faults occur in the evaluation circuit.
