Limit stop apparatus, circuit breakers including limit stops, and methods of using same

摘要

A limit stop apparatus for a multi-pole electrical contact assembly is disclosed. The limit stop apparatus interconnects crossbars of respective contact assemblies wherein one or more contact arms are pivotable relative to each crossbar. The limit stop apparatus is configured to engage the one or more contact arms on a same side of the one or more contact arms containing moveable electrical contacts. In one or more embodiments, the limit stop apparatus has a connecting bar with limit stops having arc shields molded to the connecting bar, wherein the arc shields can be phase-to-phase arc shields and contact-to-component arc shields. Circuit breakers and multi-pole electrical contact assemblies having a limit stop apparatus, and methods of operating the multi-pole electrical contact assembly are disclosed, as are other aspects.
