Abstract: A method for driving a thrust body with a bidirectional linear solenoid drive having at least in each case one first actuator and one second actuator includes the steps of providing the at least one first actuator with at least one coil and a yoke and applying force alternately to the thrust body by interacting the first actuator with at least one armature ring. The armature ring is rotated with the second actuator to thereby axially shift the thrust body by the rotation of the armature ring. The thrust body is, then, shifted axially and is subsequently fixed in position with the thrust body being shifted in steps in this way until it has reached its respective final position. Also provided is a configuration for carrying out the method.

Abstract: An electromagnetic release drive, particularly suitable for a residual current circuit breaker, includes a plunger loaded by a spring in a release direction, a permanent magnet configuration, a coil and a yoke. The coil generates in the yoke a magnetic flux opposed to the permanent magnet configuration when the coil is driven or released such that the spring force overcomes the attraction force of the permanent magnet configuration. The permanent magnet configuration and the pole shoe conducting the magnetic flux to the plunger are associated with the yoke and the plunger such that, in a first position, the plunger is located in the active range of the permanent magnet configuration and of the pole shoe and, in a second position, is located at least partly in the active range of the pole shoe.
