The arrangement serves a circuit-breaker (3), a controller (8) and a single-pole and neutral switch (9) assembled to the same rail (2) with auxiliary triggering and signalling units (4,5). The switching equipment is interconnected and/or supplied by a bus-bar (12) comprising parallel bars (14) extending along the rail and at right angles to one face (50) of the housing. Each contact stud (e.g. 40a) of the switching equipment is connected selectively to one of the bars by a double knife-edge or double gripper, one end of which cooperates with the contact studs and the other end with the bars. |
