Abstract

An actuator for circuit interrupter has a stationary magnetic boss, a movable magnetic armature and a drive rod. The drive rod is aligned on an axis of the circuit interrupter. The drive rod has two stable positions, circuit interrupter closed and circuit interrupter open. The drive rod has a surface that the armature contacts to move the drive rod from the circuit interrupter closed position to the circuit interrupter open position. In the circuit interrupter closed position, the armature and the surface are separated by a pre-travel distance. The armature is to move towards the stationary magnetic boss and contact the surface, to initiate a circuit interrupter disconnecting motion of the drive rod with a transfer of momentum to the drive rod.
