Abstract (en)

The invention relates to a drive system 20 for a circuit breaker. The drive system comprises an electromagnetic actuator 10 having a first coil 14, a second coil 15, and an armature 12 arranged to be movable between a first and a second end position by means of the coils 14, 15. In accordance with the invention both coils 14, 15 are energized simultaneously for effectuating the movement of the armature 12 between the two end positions. This is in contrast to the prior art, wherein the coils are energized one at a time; one coil for moving the armature to one of the end positions and the other coil for moving the armature to the opposite end position.
