Abstract (en)

[origin: EP0813218A2] The device has a release-armature (1) which actuates a switch lock (20). The armature (1) is actuated by a coil (3) through which the current to be monitored flows. The armature (1) is actuated by a magnetic armature (5) which is moved directly by the coil (3). The magnetic armature (5) is connected to the trigger armature (1) by means of at least on elastic coupling member (4) and preferably one or more auxiliary armatures (11). The trigger armature (1) is held in its rest position with a predetermined holding force, which is preferably a force generated in a mechanical manner. The force may be e.g. a friction force which can be generated by components in contact with the trigger armature (1) e.g. a snap spring.
