Power supply line for movable contact arm of pole of low voltage switch i.e. circuit breaker, has conductor with end having end section, which is arranged for rail, runs parallel to rotating axis of arm, and fastened to rail at front side

摘要

The power supply line has a flexible arcuate conductor (40) with an end having an end section (44') at an end (16) of a contact arm (12) and another end section at a contact rail (20). The end section at the rail is arranged in direct proximity of a pivoting range of a switching shaft. The conductor is guided between the end sections. The end section of the conductor, which is arranged for the contact rail runs parallel to a rotating axis (DW) of the contact arm, and is fastened to the contact rail at a front side. The latter end section lies between the contact arm and a base plate.
