Operating mechanism cradle assembly for high ampere-rated circuit breakers

摘要

A high strength operating cradle assembly for an industrial rated circuit breaker operating mechanism wherein the rotational action of the cradle about its pivot is controlled by interconnected operating mechanism links is disclosed. Axial positioning of the cradle on its pivot is maintained by the capture of a positioning track on the cradle pivot within a pair of guide rails on a guide pin extension on the cradle.
