ABSTRACT:
A circuit breaker switch for periodic current has a stationary contact connected to a first current terminal; a movable contact connected to a second terminal and having a closed position in which it engages the stationary contact and an open position in which it is separated from the stationary contact, an actuating device for moving the movable contact; a locking device having an operative position in which it immobilizes the movable contact in its closed position and an inoperative position in which it is clear of the movable contact; and a current intensity-responsive device connected to the locking device for moving the locking device from its inoperative position to its locking position when the intensity of current flowing through the circuit breaker switch exceeds a first predetermined value and for moving the locking device from its locking position into its inoperative position when the intensity reaches a second predetermined value.
