- 13 - ABSTRACT OF THE DISCLOSURE For use in a low-voltage switchgear there is provided the combination of a busbar and at least one electrical coupling device for screw connection or plug-in connec- tion to the busbar. The busbar is in the form of a hollow channel section bar, the cross-section of which comprises two outer branches projecting from the same side of a base. Each outer branch has a thickened edge portion along its edge remote from the base, which is provided with an open groove, the bottom of which constitutes a contact surface for said screw connection coupling devices. In its hollow interior, the busbar has contact surfaces for said plug-in coupling devices. Surfaces of the busbar other than said contact surfaces have an electrically insulating coating.
