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.

Abstract: A mechanical latching accessory kit (1) for a Medium Voltage contactor (100) comprising one or more movable contacts (101) connected through a mechanical link (110) to a contact actuator (102) moving said one or more movable contacts (101) between a contact open position and a contact closed position. The mechanical latching accessory kit (1) comprises: a supporting interface (2) adapted to be fixed to and removed from said Medium Voltage contactor (100); a latching element (3) movable between a first operating position and a second resting position; a latching actuating system (4) moving said latching element (3) between said first, operating, position and said second, resting, position; said latching element (3) being adapted, when it is in said first operating position, to cooperate with the mechanical link (110) of said Medium Voltage contactor (100) to latch said one or more movable contacts (101), and, when it is in said second resting position, to release said one or more movable contacts (101).

Abstract: A switching device including a switching unit with one or more electric poles having an insulating casing. The switching device is reversibly movable between an insertion position, at which said switching unit is electrically connected with an electric line, and a withdrawal position, at which said switching unit is electrically disconnected from said electric line. One or more actuating elements may be operatively coupleable with an actuating mechanism of a shutter device to operate one or more shutters of the shutter device during the movement of the switching device. The actuating elements may be fixed to the switching unit. At least one of the actuating elements includes a first mechanical connection with the insulating casing of at least one of the electric poles, and the insulating casing of at least one of the electric poles includes a second mechanical connection with at least one of the actuating elements.

Abstract: A mechanical override device which is suitable for an undervoltage coil of a switching unit, is comprised of a first portion suitable for urging a plunger of the undervoltage coil in a first position which is taken by the plunger when the undervoltage coil is energized, and a second portion suitable for receiving an external movement command for imposing an operating movement to the first portion. The override device further comprises movement control means for controlling one or more cinematic parameters of the first portion so as to make the operating movement independent from the external movement command.
