A limiting circuit breaker comprises two separable contacts and a mechanism with energy storage operated by an opening catch . The mechanism drives a movable cage between a closed position and an open position to perform opening of the contacts. One of the contacts is movable with respect to the cage in the closed position and can thus take a separated position. A Thomson effect electromechanical actuator is provided to drive the movable contact to the separated position. A latch enables the movable contact to be held in the separated position. In the event of a fault requiring a very high-speed response, separation of the contacts is obtained by means of the Thomson effect actuator and is then confirmed by opening of the mechanism. In other cases, only the mechanism operates to perform opening.
