The two legs of a holding magnet for ground leakage circuit breakers are arranged in juxtaposition and form a magnetic shunt. A permanent magnet at one end of the legs and the legs at such end are disposed between two pole pieces. Each of the pole pieces contacts a corresponding one of the legs and a corresponding pole face of the permanent magnet. Both pole pieces comprise a magnetic material having a higher magnetic saturation than the material of the legs. |
