Abstract (en)
1. Holding magnet tripping device for earth-leakage circuit breakers in which the yoke body (1), permanent magnet (3), tripping armature (4), excitation coil (2) and tripping spring (6) are provided in a hermetically sealed, in particular evacuated housing (10) filled with a protective gas such as nitrogen or a liquid such as silicon oil and in which the conductors for the excitation coil (2) are sealingly guided into the interior of the housing (10) characterised in that the tripping armature (4) is coupled by at least one permanent magnetic coupling with an outer lever arranged externally of the housing (10) for carrying out movements in the same direction and that one half (8b, 8c) of the permanent magnetic coupling arranged in the interior of the housing (10) is provided on a lever pivotally mounted in the interior of the housing (10), which lever is either an armature lever (5) carrying the tripping armature (4) or an internal lever (9) coupled to the tripping armature (4).
