High ampere-circuit breaker secondary disconnect arrangement

摘要

A secondary disconnect arrangement, in the form of a plug connector attached to the sides of a high ampere-rated circuit breaker assembly, interacts with a receptacle connector attached to the inner side walls of a circuit breaker enclosure. Movement of the circuit breaker in and out of the enclosure automatically connects and disconnects the plug connector from the receptacle connector. Terminals arranged on the plug connector on one side of the circuit breaker connect with internal circuit breaker components for communication and control functions, while terminals arranged on the plug connector on the opposite side provide connection between the internal circuit breaker components and remote auxiliary devices.
