  • Patent number: 7238909
    Abstract: A circuit breaker includes line and load ends and separable contacts electrically disposed between the line and load ends. A movable arm carries a movable contact and includes an elongated body having a first general longitudinal axis and an offset disposed at one end. The offset displaces the movable contact relative to the first general longitudinal axis. A line conductor carries a fixed contact and is electrically connected between the line end and the movable contact. The line conductor includes a bend portion structured to increase a gap between the separable contacts in the open position. The bend portion forms an angle which is substantially greater than 90 degrees and less than 180 degrees between the fixed contact and the second general longitudinal axis, which is generally parallel to the first longitudinal axis in the closed position. An arc chute is disposed proximate the separable contacts.

  • Patent number: 6924721
    Abstract: A gas segregator barrier is for quenching, segregating and controllably directing ionized gases discharged from a pair of spaced-apart circuit breakers double-branch mounted within a panelboard assembly. The spaced-apart circuit breakers include corresponding pairs of opposing poles, and a housing with exhaust vent openings for discharging ionized gases developed from an electrical fault. The gas segregator barrier includes at least substantially parallel segregator fins divided into first and second portions by a transverse dividing member. Baffles in the transverse dividing member quench the ionized gases and provide fluid communication between exhaust channels formed between the segregator fins of the first portion, and gas ducts disposed between the segregator fins of the second portion. The gas ducts include one or more lateral members structured to controllably direct the discharged ionized gases.

  • Patent number: 5428196
    Abstract: A switching mechanism interfaces a flexible shaft to a handle of a circuit interrupter which is rotatable in an arcuate path between an on position and an off position. The switching mechanism includes a handle attachment attached to the handle for rotating the handle between the on position and the off position, and a bracket pivotally mounted to the handle attachment and attached to the flexible shaft for movement thereby. The handle attachment may also extend a length of the handle. The switching mechanism may further include a baseplate for securing the flexible shaft thereto and attached to the circuit interrupter. The bracket may have a generally U-shape, two arms pivotally mounted to the handle attachment, and a base which is attached to the flexible shaft. The handle attachment may be generally U-shaped and have a base and two arms which each are pivotally mounted to one of the two arms of the bracket.

  • Patent number: 5412167
    Abstract: A locking device is insertable into a cover opening adjacent to a handle of an electrical switch to occupy the space in the cover opening for resisting movement of the handle. The locking device has two pivotally connected members. The pivotal movement of the members creates a collapsed condition or an expanded condition for the locking device. The pivotal members have a transverse opening which are alignable relative to each other when the locking device is in its expanded condition. The locking device is inserted into the cover opening when the pivotal members are collapsed. In a first embodiment, a handle shroud member has an opening for receiving the handle and a second member has leg means along its base for engaging an undersurface around the cover opening when the locking device is in its expanded condition. In a second and a third embodiment, both pivotal members have leg means for engaging undersurfaces around the cover opening when the locking device is in its expanded condition.

  • Patent number: 5341191
    Abstract: A molded case circuit breaker having current limiting capabilities optimized for relatively smaller frame sizes. More specifically, one aspect of the invention relates to a two-piece carrier assembly for carrying the main and arcing contact arms which allows the main and arcing contacts to be blown open during short circuit conditions. The two-piece carrier assembly includes an inner carrier and an outer carrier pivotally connected together. The contact arms are carried by the inner carrier. When sufficient magnetic repulsion forces are exerted on the contacts due to a short circuit condition, the inner carrier pivots relative to the outer carrier to allow the contact arms to blow open. In order to control the amount of force required for blow open, a compression spring loaded cam assembly is provided.

  • Patent number: 5165532
    Abstract: A circuit breaker includes an interlock which prevents movement of the handle to the off position when the contacts are welded closed. The interlock includes a pair of floating links which jam between slots in arms of the yoke of a spring powered operating mechanism which carries the handle, and recesses in the rotatable cross-bar carrying the movable contact arms. The recesses are offset from the rotational axis of cross-bar so that an attempt to move the switch to the off position generates a moment which will break open lightly welded contacts.
