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： The secondary latch of a molded case circuit breaker latching arrangement is formed from a latching pin assembly with a solid metal latching sphere rotatably mounted at one end thereof. The latching sphere contacts the operating mechanism latching plate to provide a low-friction latching force to the circuit breaker operating mechanism. The latching sphere contacts the latching plate and is continuously lubricated by means of a lubrication reservoir integrally-formed within the latch pin assembly.

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 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： A molded case circuit interrupter of the type employing a thermal-magnetic trip unit to interrupt circuit current utilizes a flexible electrical braid conductor to connect between the thermal-magnetic trip unit and the movable contact arm. A helical spring arranged around the braid conductor at the welded connection with the movable contact arm provides long-term strain relief. A metal phosphate coating on the surface of the circuit breaker operating cradle and latch assembly eliminates polishing while insuring release of the cradle from the cradle-latch interface surfaces.

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.
