ABSTRACT:
A fault current switch with a total current converter (W), whose primary circuit (1) consists of the incoming and outgoing lines of the circuit to be monitored, and whose secondary winding (2) is connected with a test circuit (P), with an electromagnetic switching device (H) for shutting off the circuit to be monitored if a fault current appears, with the working current of the holding device (H) being switchable by a switch (S1) that is supplied for the purpose with a control signal by test circuit (P), and with a power supply (EV1) for the test circuit (P) and the switch (S1). In order to make such a fault current switch both less prone to wear and also more functionally reliable, a second switch (S2) is connected in parallel with the first switch (S1), likewise for switching a working current of the switching device (H), the second switch (S2) being energized by the test circuit (P) with a second control signal that differs from the first control signal.
