    摘要: A manually operated trip operator is inserted within a recess formed in a molded case circuit breaker cover, and extends down within the breaker case to interact with the circuit breaker trip bar. The trip operator is formed from a unitary thermoplastic configuration which integrally includes means for interacting with the circuit breaker trip bar and for biasing the trip operator back to its initial position. The unitary manual trip operator is down-loaded into the circuit breaker cover in an automated circuit breaker assembly process.

    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 spring-loaded cam electrical connector is used to rapidly connect circuit breaker load terminal straps with the associated electric distribution system wire conductors. Rotation of the cam in one direction traps the end of the wire conductor between the bottom of the cam support and the circuit breaker load terminal strap to make the electrical connection while rotation of the cam in the opposite direction releases the end of the wire conductor to break the electrical connection.

    摘要: A circuit breaker enclosure consists of a cover and a case designed for robotic assembly of the circuit breaker components. A current transformer assembly and a printed wire board containing the electronic trip unit circuit are precisely positioned within the case and cover by means of a transitory circuit breaker case support platform. The transitory support platform includes four upstanding posts that pass through openings formed in the circuit breaker case and are received within corresponding openings through the circuit breaker cover. Leads extending from the current transformer assembly within the case become automatically positioned within corresponding openings through the printed wire board by means of tapered lead-in openings formed within the circuit breaker cover.

    摘要: An integrated electronic trip molded case circuit breaker includes a trip unit circuit arranged on a printed wire board contained within the breaker enclosure along with at least one circuit breaker auxiliary accessory. The condition of the integrated circuit breaker contacts is visually ascertained by a color-coded operating handle skirt subjacent indicating windows on the cover of the circuit breaker enclosure. To deter the egress of ionized gas during overload current conditions through the circuit breaker, the handle skirt seals the operating handle opening from the external environment. A groove formed within the external portion of the operating handle cooperates with an edge surface of the enclosure cover to allow the operating handle to rotate between its fully "OFF" and "ON" positions.

    摘要: A molded case circuit breaker movable contact arm or carrier electrically connects with the circuit breaker trip unit or load terminal without requiring a flexible electrical conducting braid. The contact carrier is pivotally arranged within a contact carrier support to which the trip unit or load terminal lug is attached. The contact carrier pivot pin is supported on a pair of parallel posts extending from the contact carrier and a spring clip is positioned around the parallel posts and the pivoting end of the contact carrier to promote good electric transport without interfering with the rotational movement of the contact carrier.
