Abstract:
A functional feeder unit of a low-voltage electrical cubicle containing:a vertical multipole busbar comprising conducting bars extending edgewise in parallel vertical planes staggered along the transverse direction between two flanges,a mounting plate for support and connection of an electrical apparatus,a protection grid positioned at the front of the bars, said grid being equipped with holes,and means for electrical connection of the mounting plate to the busbar comprising a connection interface with draw-in contacts, inserted between the protection grid and the mounting plate, each draw-in contact passing through a predetermined hole of the grid to engage on the bar of the corresponding phase,wherein:the mounting plate comprises coplanar current conductors presenting different lengths, with a heightwise offset in the extension direction of the bars,the draw-in contacts are arranged obliquely on a plate of the connection interface, with an offset corresponding to the distance between the bars of the different phases,and centering means which perform positioning of the plate on the protection grid to align the ends of the current conductors of the mounting plate on the bars in a direction perpendicular to the connection interface.
