    摘要: A trip interlock assembly trips a circuit breaker any time the circuit breaker is removed from its panel mounting. The trip assembly is adapted to be disposed about a load side terminal and cooperate with the circuit breaker tripping device. In one embodiment, the trip assembly includes a housing and a spring-loaded actuation arm, disposed generally perpendicular to the circuit panel surface. The actuation arm is formed with a cam surface which cooperates with a trip pin adapted to actuate said circuit breaker tripping device. The trip pin acts as a cam follower and rides along the cam surface formed in the actuation arm. When the actuation arm is in an inward position the trip pin is in a normal position. However, when the circuit breaker is removed from the panel, the actuation arm under the influence of a biasing spring moves outwardly. This causes the cam surface on the actuation arm to actuate the trip pin to trip the circuit breaker. In an alternative embodiment of the invention, the trip interlock assembly includes a bell crank with a reciprocally mounted plunger which actuates an armature in the tripping device directly, instead of by way of the trip pin, anytime the circuit breaker is removed from its panel housing.

    摘要: A circuit breaker having a trip mechanism comprising a primary armature which is attracted toward a bimetal by magnetic flux produced by a predetermined overcurrent flowing through the bimetal to unlatch an operating mechanism and open electrical contacts, includes a pivoted supplemental armature which is also attracted toward the bimetal by the overcurrent and which bears against and urges the primary armature toward the bimetal to thereby reduce the predetermined overcurrent at which the breaker opens the electrical contacts. The supplemental armature comprises a flat strip of magnetically permeable material which is bent at one end to form a hook which merely drops into a recess in the breaker housing. Integral flanges on the strip form a magnetic yoke which concentrates the magnetic flux to increase the sensitivity of the magnetic trip function.

    摘要: A miniature circuit breaker with two thermal-magnetic poles has an electronic trip device providing ground fault, and sputtering arc fault (if desired), protection located entirely in a large central compartment of a molded housing between compartments housing the two mechanical poles. The molded housing is assembled from a top base and top cover forming a compartment for the thermal-magnetic trip device of the first pole, and a bottom cover and a bottom base forming the compartment for the second mechanical pole. A hollow center piece mates with the top and bottom bases to form the single, large electronics compartment.

    摘要: An apparatus for securing a wire with a longitudinal axis includes a glass filled polyester base having a recess for housing a segment of the wire therein; and a glass filled polyester cover for at least partially covering the segment within the recess, the cover having a resilient finger which is generally transverse to the segment, the segment being generally deformed about the resilient finger within the recess in order that tension on the wire along the longitudinal axis flexes the resilient finger which, in turn, forces a portion of the segment against a side of the recess in order to secure the segment therein. The wires may have a polytetrafluoroethylene insulation.
