  • Low voltage circuit breaker with a control device for re-closing said low voltage circuit breaker
    Patent number: 9734974
    Abstract: 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.

  • LOW VOLTAGE CIRCUIT BREAKER WITH A CONTROL DEVICE FOR RE-CLOSING SAID LOW VOLTAGE CIRCUIT BREAKER
    Publication number: 20140166452
    Abstract: 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 manoeuvring means for the circuit breaker. When this shape memory material performs a state transition, the actuating element causes the movement of said manoeuvring 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.

  • Electronic driving circuit for a bistable actuator
    Patent number: 6242845
    Abstract: An electronic driving circuit for a bistable actuator activated by piezoelectric elements, particularly for residual-current devices, the circuit including a voltage step-up device suitable to step up and store a voltage generated across a secondary winding of a current sensor. The step-up device is connected to a threshold setting device suitable to determine an intervention threshold of a bistable actuator activated by piezoelectric elements, whose activation is determined by an excitation voltage applied across the bistable actuator which is higher than the voltage threshold set by the threshold setting device.
