  • Patent number: 9837229
    Abstract: A method of controlling a circuit breaker that has a movable contact and an actuator for moving the movable contact between an open position and a closed position. With the movable contact in the open position, a voltage is applied to the actuator to cause the movable contact to move towards the closed position. The voltage is applied for a limited time period ending before the movable contact reaches the closed position. At the end of the limited time period, the voltage is adjusted to reduce the acceleration exerted on the contact. The voltage is subsequently increased just before, after, or substantially at the same time as the contact reaches its closed position.
