Manual operator for circuit breaker

A circuit breaker characterized by its ability to qualify for controlling high electrical capacity in a concise configuration employing two sets of contacts separated by a dielectric barrier having anti-arcing features to minimize arcing in a minimal size circuit breaker. Control of the contact movement is through a pivoted actuator and over-center linkage in conjunction with a bell crank lever operating a spring mounted contact moving through a short radius.

Circuit breaker

A circuit breaker having two subassemblies, connected via snap-lock means, which mesh together to provide manual operation with 'trip free' response to overloads and no latch load on the bimetallic element.

The disclosure relates to a bushing that can be interlocked with an electrical circuit protector without modification thereof to provide for snap-in mounting of the protector in a panel.
