    Abstract: In one aspect, a hybrid circuit protection device for current-limiting a fault current between a source and a load during a fault is provided. The hybrid circuit protection device includes an input configured to couple to the source, an output configured to couple to the load, a return configured to couple the source to the load, a main switch configured to selectively couple the input to the output, a switching network coupled in parallel with the main switch, and a controller. The controller is configured to determine that the main switch has opened in response to the fault current, where the fault current has an initial value, and activate the switching network to current-limit the fault current to less than the initial value during the fault.

    CPC classification number: H01H33/42 H01H33/08 H01H33/53 H01H71/10

    Abstract: A low-voltage circuit breaker includes at least one fixed contact, for each pole, which is electrically connected to a terminal for connection to an electric circuit, and a corresponding moving contact which is associable/separable with respect to the fixed contact by a rotation of the moving contact. The low-voltage circuit breaker further includes an arc chamber positioned in correspondence of the fixed contact, and a rotating contact supporting shaft common to all poles, which is functionally connected to an actuation mechanism of the circuit breaker, where the actuation mechanism includes a kinematic system operatively connected to an actuation lever for opening/closing operations and provided with opening springs and a tripping shaft for releasing the kinematic system and allowing its movement from a closed to an open position. The low-voltage circuit breaker further includes, for each pole, a quick acting trip device.

    CPC classification number: H02B1/565 H02B1/38 H02B3/00

    Abstract: A low and medium voltage electrical enclosure comprising a supporting structure which defines an internal space delimited by walls forming one or more compartments housing one or more electrical apparatuses. At least one of said walls is provided with one or more venting openings that put into communication said internal space with the outside of said low voltage electrical enclosure and/or one of said compartments with a second compartment. The venting openings are provided with a cover closing a corresponding venting opening in a first—closed—operating condition at first predetermined temperatures and the enclosure is provided with an actuating device adapted to open said cover in a second—open—operating condition at second predetermined temperatures. The actuating device comprises an actuating mechanism having a Shape Memory Alloy-based (SMA-based) actuating element having a first dimension at said first predetermined temperatures reversibly changeable into a second dimension at said second predetermined temperatures, the reversible change of dimension of said SMA-based actuating element from said first dimension to said second dimension determining the reversible movement of said cover from said first—closed—operating condition to said second—open—operating condition, and vice-versa.
