A circuit breaker and a method of developing the current limiting circuit breaker are described. The circuit breaker includes a carrier assembly to supply current to a circuit through a fixed contact in a first operative state. The carrier assembly includes a latch pin to move responsive to a force transferred to the latch pin as a result of a fault condition in the circuit, a cam assembly in contact with the latch pin to move responsive to movement of the latch pin, and a movable contact coupled to the cam assembly, the movable contact breaking the physical contact with the fixed contact to put the circuit breaker in a second operative state. The circuit breaker also includes a mechanism to move the carrier assembly responsive to a signal indicative of the fault condition to put the circuit breaker in a third operative state.

Limiter type air circuit breaker with blow open arrangement

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are provided for opening circuit breaker contact arms when the circuit breaker is moved between an installed and a withdrawn position in a drawout installation.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.

Discharge mechanism for circuit breaker

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 D, 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 D, 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 portionis defined based on at least the difference between first distance Dand second distance D

Self-aligning secondary disconnect device for electrical switchgear

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.
