Abstract

In conjunction with a movable armature the yoke (16) forms a magnetic circuit with two stationary pole pieces (13,14) spaced apart for the predetermined magnetic reluctance. The pole pieces are held together e.g. by spot welds (20) with an air gap acting as a diaphragm (15). A constant magnetic flux is supplied by a rectangular permanent magnet (17) having a flat end (18) on which one end of the armature rests while the trip device is closed. The other end rests on a flat surface (19) of a projection from one pole piece (13).
