摘要： A molded case circuit breaker crossbar assembly allows the movable contact carrier, contact spring and contact carrier operating cam to be preassembled prior to insertion within the circuit breaker case. The crossbar is fabricated from a plastic molding composition having slots thereon for supporting the movable contact carrier and for retaining the charged contact operating spring. The contact carrier operating cam engages a roller carried by the operating mechanism link to couple the crossbar assembly to the circuit breaker operating mechanism.

摘要： A compact current limiting circuit breaker with an electronic trip unit arranged within the circuit breaker cover and current transformers in the circuit breaker case incorporates reinforcement ribs in the cover to provide added strength. The cover also includes line terminal plugs that removably attach to the cover for preventing inadvertent access to the circuit breaker line terminals when the circuit breaker is energized. Protrusions formed on the bottom surface of the circuit breaker cover under the trip unit provide further strength while cooperating with flexible pads on the top of the current transformers to automatically compensate for manufacturing tolerances.

摘要： A rotatable trip test assembly unit for molded case circuit breakers consists of a unitary plastic part that cooperates with the internal structure of the circuit breaker cover to provide return spring bias to the trip test button. The trip test assembly unit rotates about a pivot and strikes the circuit breaker trip bar to thereby articulate the circuit breaker operating mechanism and separate the circuit breaker contacts. The interaction between a cam-follower on the assembly unit and a cam-shaped piece within the circuit breaker cover automatically returns the trip test button to its initial position upon release.

摘要： A screw retainer is fabricated from a thin sheet of spring steel and is comprised of three sections: a screw support section, a leg support section and a leg section. The screw support section contains a through-hole for receiving a support screw. The leg support section is bounded by the screw-support section and the leg section. The leg section is angulated with respect to the leg support section and has a degree of spring action that allows it to be compressed so as to allow it and the leg support section to be inserted between the respective lower portions of integrally-formed upstanding support arms of a support base. Once the screw retainer is completely inserted between the respective lower portions of the integrally-formed upstanding support arms, the leg section springs back to its normal position thereby preventing the screw retainer from becoming dislodged from its position.

摘要： A modular crossbar arrangement for molded case circuit breakers allows a plurality of contact arm assemblies to be interconnected from a single modular unit. To provide increased acceleration to the movable contact arms a contact arm accelerator lever interfaces with the contact arm and crossbar assembly. To promote further acceleration of the movable contact arms to their closed positions, the movable contact arms in a multi-pole circuit breaker are staggered with respect to their rotational alignment within each pole on the crossbar assembly.

摘要： A molded case circuit breaker movable contact arm electrically connects with the circuit breaker load terminal without requiring a flexible electrical conducting braid. The contact arm is pivotally arranged within a contact arm support to which the load terminal lug is attached. The contact arm pivot pin is supported on a pair of parallel support posts extending from the contact arm support and a pair of bifurcated shunt plates are positioned on the pivot pin, one on each side of the contact arm to promote good electric transport between the contact arm and the support posts during short circuit conditions without interfering with the rotational movement of the contact arm.
