FIELD: electricity.
SUBSTANCE: invention relates to electrical engineering, bus bars adapters with bearing bus for fastening the switching device on them. The bearing bus is designed with a possibility of fastening on the bus bar adapter in various positions and has legs. The bus bar adapter has clearance holes, through which respectively one of legs of the bearing bus with latch protrudes from the first limiting surface of clearance holes, to which the bearing bus adjoins, to the second limiting surface of clearance holes so far, that the respective latch of the leg with retaining surface is located at a distance from the second limiting surface, which corresponds to the size of the gate, which slides with geometrical closure between the retaining surface of the latch and the second limiting surface.
EFFECT: simplification of fixing at the expense of avoidance of use of accessories.
