Abstract:
A secondary disconnect arrangement, in the form of a plug connector (51) attached to the sides of a high ampere-rated circuit breaker assembly (10), interacts with a receptacle connector (28) attached to the inner side walls (34, 35) of a circuit breaker enclosure (33). Movement of the circuit breaker (10) into and out of the enclosure (33) automatically connects and disconnects the plug connector (51) from the receptacle connector (28). Terminals (30) arranged on the plug connector (28) on one side of the circuit breaker (10) connect with the internal circuit breaker components for communication and control functions via components (29, 31), while terminals (41-44) arranged on the plug connector (28) on the opposite side provide connection via terminal array (70-73) between the internal circuit breaker components and remote auxiliary devices.
