Tripping device for a circuit breaker, especially a residual-current circuit breaker

The triggering device is intended for a circuit breaker, especially a residual-current circuit breaker and has seated a on a yoke (9), spring-loaded moving armature (5), a to the armature (5) coupled actuator (4) and a Notausloser (17) on. The Notausloser (17) is independent of the armature (5) triggered formed and / or he has a fixed bearing and on the side remote from the actuating element (4) page on the armature (5) adjacent encoder (18) on which electric and / or magnetic input variables converts into mechanical output quantities. DOLLAR A Such a trigger is characterized by a particularly high redundancy because he also almost certainly trigger when the armature (5) on the yoke (5) is fixed by gluing.
