1. A method of adjusting holding magnet tripping devices, in particular for earth-leakage circuit breakers (1), characterized in that the holding magnet tripping device is arranged in a magnetic field the direction of which is rotated, preferably stepwise, until the magnetisation of the permanent magnet (3) and thereby the permanent flux through the tripping armature of the holding magnet tripping device is changed to such an extent that the tripping armature drops away from the yoke body when a tripping current of predermined strength flows through the excitation coil. |
