ABSTRACT:
For connecting a shunting impedance to a contact rod of a circuit breaker, there is provided an impedance contact assembly comprising a metal ring, two slots in the ring at diametrically-opposed locations, and a U-shaped metallic spring member having two spaced-apart arms and a bight portion. The spring member, which is positioned with its bight portion in one slot and the free ends of its arms in the other slot, has a resilience tending to bias the arms apart and against the walls of said other slot. The contact rod has a path of movement that extends between the spaced arms so that the arms slidably engage the contact rod at its opposite sides as the contact rod moves along this path.
