Abstract

An assembly (10) for a low voltage withdrawable switching device, comprising: a supporting frame (11) into which / from which a switching unit (20) of the withdrawable switching device can be inserted / withdrawn; at least one first connector (12) placed at and protruding from a bottom portion of the supporting frame, which is adapted to be coupled with a second connector (22) of the switching unit; and a shutter assembly (100). The shutter assembly comprises: an opening (110) for allowing the coupling between the first and second connectors; and at least one cover member (102, 103) 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 at least one 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 at least one cover member from the cover to the open position by the first connector.

Description

technical field [0001] The invention relates to an assembly for a low voltage withdrawable switchgear. Background technique [0002] Switches, usually circuit breakers, disconnectors and contactors, used in low-voltage circuits—that is, circuits having applicable voltages below 1 kV AC (alternating current) and 1.5 kV DC (direct current)—as known A device is a device designed to allow the correct operation of a particular part of the electrical circuit in which it is installed and of the associated electrical load. [0003] A low voltage switchgear comprises a switch unit having a main housing housing one or more poles or phases, each pole or phase comprising at least one movable contact and a corresponding stationary contact. [0004] The drive mechanism actuates the movable contact between a closed position, in which the movable contact is coupled to a corresponding fixed contact, and an open position, in which the movable contact is coupled to a corresponding fixed conta...
