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 molded case circuit breaker interlock unit connects between a fuse enclosure attached to one end. Upon the occurrence of a short circuit within a protected circuit, the fuse operates to isolate the protected equipment and is conveniently replaced without disassembling the circuit breaker components. The interlock unit prevents resetting the circuit breaker operating mechanism until the fuse is replaced.

摘要： An undervoltage release accessory is attached to the interior of a circuit breaker enclosure proximate the operating handle assembly. A reset mechanism positioned between the handle operator and the undervoltage release plunger resets the undervoltage release plunger after an undervoltage condition. A flexible reset spring on the reset mechanism compensates for mechanical tolerances between the reset mechanism and the undervoltage release plunger.

摘要： An electric circuit breaker operating mechanism includes an insulated armature latch which prevents deleterious arc formation between the operating mechanism cradle and the armature latch surface when the circuit breaker contacts are separated under overcurrent circuit conditions. The insulated armature latch carries a tolerance take-up spring which interacts between the operating mechanism cradle and the circuit breaker trip bar assembly to insure free travel of the operating cradle during contact separation.

摘要： Molded case circuit breaker accessories using slightly modified circuit breaker cases are described. Several of the accessories utilize a microswitch to provide remote indication of an auxiliary function. One modification of the circuit breaker case includes upstanding posts to capture and position the microswitch while a further modification utilizes the magnetic trip unit adjustment screw and a support plate.
