The invention relates to a triggering device (100) for an electromechanical protective switching device (1), for a line protection switch or a circuit breaker, for example, having a magnetic coil (101) and an armature-tappet assembly, comprising an armature (102) and a tappet (103), which is movable relative thereto by means of the magnetic coil (101) from a rest position to a triggered position. The triggering device (100) furthermore has a reset apparatus (120) which is coupled to the armature-tappet assembly such that the armature-tappet assembly can be reset from the triggered position into the rest position by means of the reset apparatus (120). The reset apparatus (120) is movably mounted in a housing (2) of the protective switching device (1) between a first position and a second position and designed such that, after a movement of the armature-tappet assembly into the triggered position, the reset apparatus only temporarily has effect thereupon in order to reset the reset apparatus from the triggered position to the rest position thereof. By means of the reset apparatus (120), it is ensured that the triggering device (100) is restored to a triggering-ready state after triggering has occurred. As a result of using the reset apparatus (120) instead of an armature spring, the movement of the armature-tappet assembly does not counteract any of the spring force caused by the armature spring during the triggering movement thereof from the rest position to the triggered position. The switching behavior of the protective switching device is thus significantly improved.
