Abstract

Said device operates with an armature holder (2) which is guided on the trip-device housing (1) and holds a small armature plate (3) which is retained by it, in a direction which is parallel to the pole surface (4) of the magnet. The armature holder is subject to the influence of a trip spring (6). The armature holder and a tripping lever (5) are connected to one another, like a driver, in such a manner that the tripping lever can be moved further once the armature holder is resting against a stop (7). This further movement can likewise continue as far as a stop for the tripping lever. <IMAGE>
