摘要： A handle interlock arrangement is attached to the top surface of a manually operable circuit breaker operating handle to prevent the handle from being locked in its "OFF" position when the circuit breaker contacts are actually in their closed condition. A handle cover is hingeably attached to the circuit breaker cover and includes a pair of apertures arranged through the opposite sidewalls of the cover. The location of the apertures relative to the circuit breaker operating handle prevents the insertion of a padlock through the apertures when the circuit breaker operating handle is in its "ON" position.

摘要： An integrated protection unit is a circuit breaker which includes basic overcurrent protection facility along with selective electrical accessories. A molded plastic accessory access cover secured to the integrated protection unit cover protects the accessory components contained within the integrated protection unit cover from the environment. A combined overcurrent trip actuator and multiple accessory unit can be field-installed within the integrated protection unit. The combined actuator-accessory unit includes electronic control circuitry for the accessories along with mechanical trip and reset interface components. The reset mechanism allows the actuator-accessory unit to become reset without interferring with the operation of the integrated protection unit.

摘要： A circuit breaker operating mechanism employs a multi-latch arrangement for controlling the automatic opening of the circuit breaker contacts upon predetermined overcurrent conditions. The multi-latch assembly is robotically assembled to the operating mechanism and is retained thereon by means of a retainer tab. The circuit breaker case and cover contain integrally formed steps which receive extensions formed on the operating mechanism assembly. The operating mechanism assembly becomes wedged between the circuit breaker cover and case when the cover is later fastened to the case.

摘要： An industrial rated molded case circuit breaker having an electronic trip circuit contained within the circuit breaker enclosure includes a reset spring in cooperation with the circuit breaker latch spring to insure manual reset of circuit breaker after an automatic trip function. The reset spring allows the circuit breaker latch assembly to be manually reset upon minimum travel of the circuit breaker operating handle due to internal circuit breaker component space restrictions. The circuit breaker latch assembly is robotically loaded to the operating mechanism which is then attached to the circuit breaker case by an automated fastening process.

摘要： A combined trip actuator and accessory module for molded case circuit breakers is accessible in the field for user selected accessory options. The trip actuator includes a U-shaped stator with a permanent magnet at the end of one leg. A spring-loaded armature member extends across both legs to form a closed-loop magnetic circuit. The over-current trip coil and shunt trip coil are arranged on one leg with the undervoltage coil arranged on the other leg. The accessory module is accessible from the top surface of the breaker cover for field installation of the undervoltage and shunt trip coils to provide the corresponding undervoltage and shunt trip functions.

摘要： An electronically driven trip actuator for multipole industrial rated molded case circuit breakers is installed within a common housing with the circuit breaker operating mechanism. The trip actuator consists of a mechanical actuator cooperatively connected with a magnetic latch. The magentic latch arrangement holds the trip actuator against an actuating spring bias. Upon receiving an appropriate signal response, the magnetic latch releases, allowing the mechanical actuator to move into contact with the circuit breaker latch under the influence of the actuator spring. The arrangement of the mechanical actuator and actuator spring provides a low latching force to the magnetic latch, while providing a large trip force to the circuit breaker latch.
