An electromagnetic drive unit and an electromechanical switching device

摘要

An electromagnetic drive unit (20) comprises a coil (21), a yoke (22) and an armature (23A). The winding (41) of said coil (21) is partly wound in one direction and partly in the other direction. An electromechanical switching device (10) comprises at least one input terminal (A1) and a respective output terminal (T1) and an electromagnetic drive unit (20) adapted to limit or to break the electrical current between said at least one input terminal (A1) and the respective output terminal (T1).
