BUSBAR TRUNKING UNIT AND BUSBAR TRUNKING SYSTEM COMPRISING A BUSBAR TRUNKING UNIT

The invention relates to busbar trunking unit (102; 202) for a busbar trunking system (101), comprising busbars (104; 204) which are elongated in a longitudinal direction (103; 203), are arranged flat next to one another in the busbar housing (105; 205) and are encased by a busbar housing (105; 205), each busbar (104; 204) comprising a first recess (160; 260) on a first end and a second recess (161; 261) on a second end, wherein the recesses (160, 161; 260, 261) serve in each case for receiving a bolt (152) of a single-bolt connection via which the busbars (104; 204) can be connected in an electrically conductive and mechanical manner to associated busbars of adjacent busbar trunking units of the busbar trunking system. According to the invention, the busbar housing (105; 205) comprises two lateral profiled elements (112, 122, 113, 123; 212, 213) and two covering profiled elements (111, 121; 211, 221), wherein the lateral profiled elements (112, 122, 113, 123; 212, 213) have openings (162; 262) for actuating the single-bolt terminals and wherein a first of the covering profiled elements (111; 211) protrudes the first ends of the busbars and the second of the covering profiled elements (121; 221) protrudes the second ends of the busbars (104; 204). In order to design the busbar trunking unit in a more cost-effective and secure manner, it is provided that the lateral profiled elements (112, 122, 113, 123; 212, 213) and the covering profiled elements (111, 121; 211, 221) are made of an electrically conductive material and are electrically connected to one another such that they form a current path that can be used as a PE conductor.
