Rubber stops in outside poles.

摘要

A molded case circuit breaker provided with rubber stop assemblies between the contact assemblies. The stop assemblies prevent the contact assemblies from damaging the cover, and include U-shaped bracket having two parallel sets of arms. One set of arms is provided with aligned apertures at the free ends for receiving a pin for a pivot point for the crossbar assembly. The other set of arms is provided with aligned apertures at the free end for receiving a metal pin for carrying a cylindrical shock absorber assembly. When the contact arm is opened, it will stop against the shock absorber and not damage the circuit breaker cover. The center pole is provided with an adjacent shock absorber, spaced away from the operating mechanism.
