Abstract

The invention relates to a switching device for an electrical distribution board, comprising a ground fault circuit interrupter (1) and at least two circuit breakers (8) mounted downstream thereof which protect one electric circuit each. The aim of the invention is to provide a system which allows to quickly reconnect the faultless electric circuits to the net once the ground fault circuit interrupter has been activated. For this purpose, a relay (7) is mounted directly upstream or downstream of each circuit breaker (8) and the relays (7) are controlled by a control unit (6) that controls a reclosing device (3) associated with the ground fault circuit interrupter (1). Said control unit (6), after activation of the ground fault circuit interrupter (1), opens the relays (7), controls the reclosing device (3) for switching on the ground fault circuit interrupter (1) and then sequentially closes the relays (7) according to a predetermined program.
