ABSTRACT:
An overcurrent release device for protection switching devices, in particular automatic line circuit breakers or motor protective switches, with electromagnetic and thermoelectric release, includes a thermoconducting tubular supporting body onto which a coil is wound and which has a striking end and an opposite widened receiving end for bearing contact and radial support of a bimetal snap-action disk with a central bore, a core having a bore defined therein, an armature movable in the supporting body between its striking end and the core, and a slide extending through the bore in the snap-action disk and through the bore in the core in a direction towards the armature. The slide is provided for thermoelectric disengagement by means of the snap-action disk via a thickened portion and for electromagnetic disengagement by means of the armature via a slide actuator. In the operative state, the spacing between the armature and the core corresponds at maximum to the snapping travel of the snap-action disk.
