Abstract
1. A fault current circuit breaker having a testing device which contains a test key (14) ; a switching mechanism which, in the event of a current inbalance of the phase conductors and the neutral conductor which are led through a totalising current transformer (2), can be unlatched by means of a magnetic tripping device (3), and which switching mechanism interrupts the tested conductors by means of a contact system (7) on a drum switch (4) ; and a carrier to which the switching mechanism, the magnetic tripping device and the drum switch of the contact system are commonly secured so as to be insertable into the housing, characterised in that the test key (14) is raised into the normal (rest) position by a V-shaped spring (15), in the resilient region of which, there is arranged a bared winding (16) of the neutral conductor of the primary winding, which is located on the summation current transformer (2), and that the V-shaped spring (15) is electrically connected to one phase.
