Abstract: An assembly for a low voltage withdrawable switching device, comprising: a supporting frame into which/from which a switching unit of the withdrawable switching device can be inserted/withdrawn; a first connector placed at and protruding from a bottom portion of the supporting frame, which is adapted to be coupled with a second connector of the switching unit; and a shutter assembly. The shutter assembly comprises: an opening for allowing the coupling between the first and second connectors; a cover member which is adapted to be moved from a cover position to an open position so as to make the opening accessible for the coupling between the first and second connectors. The cover member is adapted to be moved from the cover position to the open position by the first connector. The shutter assembly is operatively mounted movable into the supporting frame. The shutter assembly is adapted to operatively interact with the switching unit under insertion into the supporting frame so as to be moved towards the bottom portion for causing the movement of the cover member from the cover to the open position by the first connector.

Abstract: The present application is directed to a switching device for LV electric installations. The switching device can include an outer casing and one or more electric poles. Each electric pole can include one or more mobile contacts and one or more fixed contacts adapted to be coupled or uncoupled. A mobile contact assembly is operatively coupled with the mobile contacts such that the mobile contacts move together with the mobile contact assembly, The mobile contact assembly is adapted to reversibly move between a first contact position, in which said movable contacts and the fixed contacts are coupled and a second contact position, in which the movable contacts and the fixed contacts are uncoupled. A mechanical control assembly is provided for operating said mobile contact assembly.
