A system and apparatus for maintaining the desired synchronous and asynchronous A and B auxiliary electrical circuits, respectively, by use of connector block halves, one connector block half being connected to wiring out for auxiliary circuitry and being secured to the movable circuit breaker and the other auxiliary connector block half also being connecting to wiring out for auxiliary circuitry and secured to the relatively stationary wall or surface of the cubicle, where the connector block halves have some portion of its contacts of the “make before break” type so that the A and B auxiliary circuits operate as intended when the connector halves are connected and the A and B auxiliary circuits still reflect the proper condition, synchronous or asynchronous, of the A and B circuits, respectively, even when the auxiliary connector block halves are physically and/or electrically separated from one another.
A system for maintaining coordination of synchronous and asynchronous condition of A and B type auxiliary circuits, respectively, of a power circuit breaker selectively removable from a cubicle for housing the same, the system comprising:
A power circuit breaker comprising a movable circuit breaker and a stationary housing cabinet for said circuit breaker having auxiliary electrical circuits of the A and B type to reflect an open condition or a closed condition of said circuit breaker wherein said auxiliary electrical circuits are provided with a first, movable electrical connector block secured to said movable circuit breaker, and a second mating electrical connector block secured to said stationary housing cabinet, wherein said first and said second electrical connector blocks have at least one B type circuit of the make before break type.
A power circuit breaker system of the rack-able in and rack-able out type comprising a movable circuit breaker with respect to a housing for the same, said circuit breaker having male connectors which mate with female connectors of said housing wherein a rod is secured to a first auxiliary electric circuit connector block secured to the movable circuit breaker, wherein a second and stationary auxiliary electric circuit connector block, mate-able with said first auxiliary electric circuit connector block, is secured to said housing, wherein movement of said rod provides for connecting and disconnecting said first and said second auxiliary electric circuit connector blocks to and from one another, and wherein said connection of said first and said second auxiliary electric connector blocks is a consequence of a relative sliding movement of said rod through said circuit breaker to push said first auxiliary electric circuit connector block towards said second auxiliary electric circuit connector block.
