Circuit breaker mechanism for a rotary contact system

摘要

A rotary contact circuit breaker (10) employs a crank to couple a switching mechanism (12) to the rotary contact pole structure (14C, 14L, 14R). The use of a crank allows for the mechanism (12) and pole structure (14C, 14L, 14R) to be individually optimized without effecting the performance of the other. In particular the crank allows for a mechanism that is able to achieve maximum torque delivery to the pole structure. <IMAGE>
