Fault current protection device, switching mechanism and system

Ground fault circuit interrupter, has control device automatically executing function test on switching mechanism, and shaft blocked by locking device during function test, such that current flow over switching contact remains constant

Arrangement for testing contact system of e.g. miniature circuit breaker, has moving mechanism opening switching contact for testing by utilizing moving contact that is movable independent of switching mechanism of circuit breaker
