摘要： A circuit breaker design and process for high speed assembly utilizes a unique secondary latch arrangement to reduce frictional forces and increase the breaker calibration test yield. The design allows for interchangability of the trip unit by first pre-assembling the arc chute cavity and operating mechanism. Arrangement of the primary and secondary latch pivots reduces the trip force for further increase in the calibration yield.

摘要： An interchangeable operating mechanism assembly for molded case circuit breakers having a detachable movable contact arm and trip unit assembly allows the same mechanism assembly to be employed across a wide range of breaker ratings. A snap-on common trip bar attachment further allows multiple-pole facility off the common interrupter mechanism assembly. The mechanism assembly is designed to maintain the operating handle in the "on" position upon the occurrence of a welded contact and prevents the mechanism from being reset.

摘要： A composite line strap is used with molded case circuit breakers to support the circuit breaker stationary contact and to retain the circuit breaker line terminal screw. The fixed contact is welded to the line strap within the breaker at a first end and the line terminal screw is attached to the opposite end of the line strap by a through-hole in a spring-steel retainer which extends partially within the circuit breaker. The line terminal screw is tightly held within the through-hole of the retainer at the first end and the retainer itself is trapped between the bottom of the circuit breaker case and the line strap at the opposite end of the line strap.

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.

摘要： A compact three-pole circuit breaker is modularly constructed utilizing two identical operating mechanisms in controllably articulating three movable contact arms. The operating mechanisms are ganged together for concerted manual operation by an external handle tie and internal means intercoupling the three movable contact arms and the operating mechanisms. Trip units, one in each breaker pole, independently act on an internal common trip bar to simultaneously trip the two operating mechanisms and thereby effect concerted opening movement of the contact arms in quick break fashion under the urgence of mechanism springs and assisting helper springs.
