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 auxiliary/control switches kit box for a Medium Voltage switching device including one or more movable contacts operated between a contact open position and a contact closed position by a kinematic chain connected to a contact actuator. The auxiliary/control switches kit box includes: a shaped enclosure adapted to be inserted into and removed from a dedicated volume inside the Medium Voltage switching device; the shaped enclosure housing one or more auxiliary/control switches electrically connected to corresponding one or more terminal boards; the one or more terminal boards facing toward the outside of the shaped enclosure from a first face of the shaped enclosure; the one or more auxiliary/control switches each including a pair of auxiliary/control switch contacts that can be linearly operated by an auxiliary/control switch actuator between a normally open (NO) position and a normally closed (NC) position; a mechanical coupling system mechanically connected to the auxiliary/control switch actuator to linearly displace it between the NO position and the NC position; the mechanically coupling system having one or more operating levers protruding outside the shaped enclosure from a second face thereof and being adapted to cooperate with the kinematic chain of the Medium Voltage switching device and follow it during the movement from the contact open position and the contact closed position.

Abstract: A switching apparatus including one or more electric poles. For each electric pole, the switching apparatus includes a first pole terminal, a second pole terminal, a ground terminal, and a plurality of fixed contacts spaced apart one from another. For each electric pole, the switching apparatus further includes a movable contact and a vacuum interrupter. The movable contact is reversibly movable about a corresponding rotation axis. The vacuum interrupter includes a movable arc contact reversibly movable along a corresponding translation axis. For each electric pole, the switching apparatus further includes a motion transmission mechanism operatively coupled to a contact shaft solidly coupled to the movable arc contact. The motion transmission mechanism is actuatable by the movable contact to cause a movement of said movable arc contact along said translation axis, when said movable contact moves about said rotation axis.

Abstract: A switching apparatus includes one or more electric pole units, each electric pole unit comprising a fixed contact, a movable contact, a first pole terminal, a second pole terminal, and a motion transmission arrangement to reversibly move the movable contact. The motion transmission arrangement includes a conductive motion transmission member coupled to the movable contact. The first pole terminal is in electrical connection to the fixed contact while the second pole terminal includes a first coupling region in electrical connection with a second coupling region of the conductive motion transmission member. Each electric pole unit further includes a shielding element formed by a conductive hollow body and arranged in a relative fixed position with respect to the second pole terminal and the motion transmission member. The shielding element is arranged to at least partially surround the first coupling and the second coupling region.

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.
