Self-aligning secondary disconnect device for electrical switchgear

摘要

A secondary disconnect apparatus for a circuit breaker, for making a slidable electrical connection with a mating enclosure-side secondary disconnect apparatus, is disclosed, having a pair of stop plate surfaces coupled to the circuit breaker defining a first linear distance D1, and a lateral adjustment portion in slidable communication with a pair of a guide members configured to guide movement of the lateral adjustment portion along an axis in one of a first and a second direction. The apparatus includes and a pair of adjustment member surfaces coupled to the lateral adjustment portion defining a second linear distance D2, wherein the adjustment member surfaces are configured to cooperate with the stop plate surfaces to limit the travel of lateral adjustment portion, and wherein a total predetermined lateral distance of travel of lateral adjustment portion 250 is defined based on at least the difference between first distance D1 and second distance D2.
