Abstract
1. Magnetic trip for residual-current-operated circuit breakers comprising a permanent magnet (22), a coil (20) with metal core (18), a yoke (12), an armature (28) which can be rotated by means of spring force and is supported on a support plate (34) of the yoke (12), and a plunger (47) which can be operated by means of this armature, for tripping the latching mechanism, the yoke (12) with the metal core (18), cantilevering into the coil (20) and the armature (28) consisting of a highly permeable metal alloy with a low coercive force, characterized in that - the yoke (12) consists of two yoke plates (14, 16) which rest against one another separated by a magnetically poorly conducting diaphragm (48) with one integral support (38) each for the armature support, in which arrangement an integral coupling-in point (26) for the permanent magnet flux being constructed at one end each and, at the other end, the pole face (30) of one yoke plate (16) or of the metal core (18) in the coil (20) and the pole face (32) of the other yoke plate (14) which is not protruding into the coil (20) engages the armature (28) in a contact-making manner, and - in the area of the axis of rotation (B) of the armature (28) at least one magnetically poorly conducting zone is formed which prevents a magnetic short-circuit between the two yoke plates (14, 16).
