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a supporting frame into which/from which a switching unit of the withdrawable switching device can be inserted/withdrawn; a first connector placed at and protruding from a bottom portion of the supporting frame, which is adapted to be coupled with a second connector of the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: Exemplary embodiments are directed to a direct current switching apparatus including at least a first mechanical switching device which is suitable to be positioned along an operating path of an associated DC circuit and includes a fixed contact and a corresponding movable contact which can be actuated between a closed position and an open position along the operating path, wherein an electric arc can ignite between the contacts under separation. The switching apparatus includes an electronic circuit having a semiconductor device which is suitable to be positioned along a secondary path and connected in parallel with the first mechanical switching device. The electronic circuit can be configured to commute the flow of current from the operating path to the secondary path and extinguish an electric arc ignited when the movable contact separates from the fixed contact when the first mechanical switching device fails to extinguish the same.
