Low voltage circuit breaker with a control device for re-closing said low voltage circuit breaker

The present invention refers to a low voltage circuit breaker with a control device for re-closing said low voltage circuit breaker. The control device is provided with an actuating element, comprising a shape memory material and operatively associated with maneuvering means for the circuit breaker. When this shape memory material performs a state transition, the actuating element causes the movement of said maneuvering means from a first operative position, associated with an open configuration of the circuit breaker, to a second operative position, associated with a closed configuration of the circuit breaker.
