Abstract (en)

A tripping device for opening the contacts of a circuit breaker associated therewith following the detection of a residual current exceeding a preset limit by a detecting device, comprising an enclosure for containing and supporting a kinematic mechanism which has: an actuation lever and a tripping lever, which are geometrically coupled to each other and are both pivoted on a first pivot of the enclosure, the actuation lever being operatively connected to an actuator which is actuated by the detecting device; an indicator lever, with which an actuation spring is associated, and a transmission lever, said indicator and transmission levers being mutually operatively coupled and being both pivoted on a second pivot of the enclosure, said transmission lever having a coupling pivot for coupling to the kinematic system of the associated circuit breaker; an engagement lever, which is geometrically coupled to the indicator lever and is detachably connected to the tripping lever. <IMAGE>
