摘要： Disclosed herein is a method of moving and altering movement of a breaker mounted spring discharge interlock lever during racking and unracking of a breaker with an enclosure. The method includes, rotating a racking screw to rack the breaker into or out of the enclosure, rotating a shaft in operable communication with the racking screw, translationally moving a cam with a link having one end disconnectably connected to the cam and an opposing end disconnectably connected to a crank, that is fixedly attached to the shaft, translationally moving a cam follower that is in operable communication with the cam, moving the breaker mounted spring discharge interlock lever that is in operable communication with the cam follower, and enabling removal and replacement of the cam by disconnecting the cam from the link, thereby enabling the movement of the breaker mounted spring discharge interlock lever to be altered.

摘要： A circuit breaker and mechanism are provided for opening circuit breaker contact arms when the circuit breaker is moved between an installed and a withdrawn position in a drawout installation. The circuit breaker has a cross shaft coupled to a first linkage that rotates in response to the circuit breaker being moved. A second linkage translates in response to said first linkage rotating. A cam surface is operably coupled between the cross shaft and the first linkage. An opening latch shaft is coupled between the second linkage and a contact arm assembly such that the opening latch shaft moves the contact arm assembly from a closed position to an open position in response to the translation of the second linkage.
