Abstract: The invention relates to a method (100) for detecting faults in a LVDC electric line (500) characterized in that it comprises the following steps: acquiring (101) a first detection signal (VLOW) indicative of low-frequency components of an unbalancing current (IG) between a plurality of conductors of said electric line, said first detection signal being obtained by means of a low-pass filtering of a corresponding measuring signal (VM1) indicative of said unbalancing current; acquiring (102) a second detection signal (VHIGH) indicative of high-frequency components of an unbalancing current (IG) between a plurality of conductors of said electric line, said second detection signal being obtained by means of a high-pass filtering of a corresponding measuring signal (VM2) indicative of said unbalancing current; obtaining (103) a third detection signal (RT) by calculating the ratio between said first and second detection signals (VLOW, VHIGH); checking (104) whether a DC current (IF) is present by comparing said third detection signal (RT) with a first threshold value (TH1). In a further aspect, the invention relates to an electronic device (1) including processing means for carrying out said method.

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a supporting frame into which/from which a switching unit of the withdrawable switching device can be inserted/withdrawn; a first connector placed at and protruding from a bottom portion of the supporting frame, which is adapted to be coupled with a second connector of the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.
