An electrical switching device which enables an electrical system, particularly a power distribution system, is structured rationally and simply. The switching device, in particular embodied in the form of a rail-mounted device, contains a housing and, included therein, a switching unit for interrupting an electrical circuit, and a supply connection for feeding a current to the switching unit. The supply connection has a first coupling contact for connecting to a current busbar, a load connection for connecting a feed conductor of a load circuit to the switching unit, and a return connection which has a connecting terminal for connecting to the return conductor of the load circuit and a second coupling contact connected to the connecting terminal inside the housing for connecting to a second current busbar.
