Abstract: A method and system for driving an actuator of a circuit breaker are disclosed. The method includes supplying a coil of the actuator with a first voltage, wherein the coil can generate a magnetic field, which can cause an armature to move relative to a stator of the actuator from a closed position to an opened position. A second voltage of reverse polarity can be supplied to the coil with respect to the first voltage while the armature is moving relative to the stator, such that the coil can generate a reverse magnetic field, which decelerates the relative movement of the stator and the armature.
