    Abstract: A mechanical latching accessory kit for a Medium Voltage contactor including one or more movable contacts connected through a mechanical link to a contact actuator moving the one or more movable contacts between a contact open position and a contact closed position. The mechanical latching accessory kit includes: a supporting interface adapted to be fixed to and removed from the Medium Voltage contactor; a latching element movable between a first operating position and a second resting position; a latching actuating system moving the latching element between the first, operating, position and the second, resting, position; the latching element being adapted, when it is in the first operating position, to cooperate with the mechanical link of the Medium Voltage contactor to latch the one or more movable contacts, and, when it is in the second resting position, to release the one or more movable contacts.

    Abstract: An electric terminal for an electric pole unit of a switching device, the electric terminal being adapted to be electrically connected to a current breaking unit of the electric pole unit and to an external conductor and being adapted to be inserted in a corresponding shaped port of an insulating housing of the electric pole unit. The electric terminal comprises one or more first coupling surfaces mating with one or more second coupling surfaces of the insulating housing, the first coupling surfaces abutting against the second coupling surfaces when the electric terminal is inserted in the corresponding shaped port of the insulating housing in such a way to obtain a mechanical coupling by friction between the electric terminal and the insulating housing.

    Abstract: Systems, methods, techniques and apparatuses of contactors are disclosed. One exemplary embodiment is a contactor including an electric pole, a pair of plungers, and a pair of opening springs. The electric pole includes a fixed yoke member and a movable yoke member arranged respectively at a proximal position and a distal position with respect to a movable contact. The fixed yoke member includes a pair of through holes. The pair of second plungers are inserted in a corresponding through hole passing through the fixed yoke member and symmetrically positioned with respect to a main symmetry plane of the contactor, which is parallel to a displacement axis of the movable contact and perpendicular to a displacement plane of the movable contact. The pair of opening springs are symmetrically positioned with respect to the main symmetry plane.
