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; the venting openings are provided with a cover closing a corresponding venting opening in a first—closed—operating condition. The enclosure is provided with an actuating device adapted to open said cover in a second—open—operating condition in case of arc fault inside said internal space; said actuating device comprises an actuating mechanism having a Shape Memory Alloy-based (SMA-based) actuating element having a first dimension at first predetermined temperatures reversibly changeable into a second dimension at second predetermined temperatures. The reversible change of dimension of said SMA-based actuating element from said first dimension to said second dimension determines the reversible movement of said cover from said first—closed—operating condition to said second—open—operating condition, and vice-versa.

Abstract: A pole actuation booster mechanism for a four-poles low voltage circuit breaker, which includes: a first operating member adapted to be operatively connected to the operating shaft of the circuit breaker and moving together with said shaft during its rotation from an open position to a closed position, and vice-versa, of said circuit breaker over a range of movement having a first, a second and a third portion of movement, the first operating member having a first operating end; an operating assembly including at least an elastic element operatively connected to a lever, the first operating member being disengaged from said operating assembly during the first portion of its movement and engaged with the lever during the second and third portions of its movement. During a closing operation of the circuit breaker the first operating member moves first along the first portion of movement driven by the operating shaft and disengaged from the operating assembly, then moves along the second portion of movement driven by the operating shaft and engaged with the lever and transmitting energy to the operating assembly; and finally moves along the third portion of movement driven by the lever and transmitting energy to the operating shaft.

Abstract: A switching device including a switching unit having one or more electric poles and including, for each electric pole, a first power contact and a second power contact along which a line current can circulate and one or more solid-state switches; and a supporting frame adapted to be fixed to a supporting structure and including, for each electric pole, a third power contact and a fourth power contact along which said line current can circulate. The switching unit is reversibly movable, with respect to said supporting frame, between an insertion position and a withdrawn position. The switching unit includes, for each electric pole, at least a hydraulic circuit along which a cooling fluid can circulate to remove heat generated by said solid-state switches. The hydraulic circuit includes a first hydraulic connector and a second hydraulic connector that are coupled with or separated from a corresponding third hydraulic connector and a corresponding fourth hydraulic connector of said supporting frame, when said switching unit is in said insertion position or in said withdrawn position.
