摘要： An accessory (66) includes a trip arm (104) biased by a spring (106) to pivot in a clockwise direction about a trip arm pivot (120). A latch (110) is arranged to pivot about a latch pivot (132) and has the trip arm (104) acting on a latch surface (126) on the latch (110) to bias the latch (110) in a counter clockwise direction about the latch pivot (132). An electromechanical device (102) including a plunger (130) acts on the latch (110) pulling it clockwise about he latch pivot (132). When a signal is provided to the electromechanical device (102), the plunger (130) is released allowing the trip arm (104) to pivot clockwise about the trip arm pivot (120) due to the spring (106) and actuates the operating mechanism (30). To reset the trip arm (104) and the latch (110), a reset lever (108) is arranged to pivot about the latch pivot (132). The reset lever (108) includes a tab portion (72) configured for interfacing the operating mechanism (30), and a drive portion (142) for interfacing the trip arm (104). This, when the operating mechanism (30) is reset, a portion extending from an operating handle (28) interfaces the tab portion (72) to pivot the reset lever (108) clockwise about the latch pivot (132). The drive portion (142) interfaces the trip arm (104) to drive the trip arm (104) counterclockwise about the trip arm pivot (120).

摘要： A compact current limiting circuit breaker utilizing two pairs of series connected contacts is equipped with a current limiter arranged in parallel with the second pair of contacts for improved overcurrent protection. Upon the occurrence of contact separation an arc is drawn at the first pair of contacts, but not the second. The presence of the polymer current limiter in parallel with the second pair of contacts causes the overcurrent to commutate into the polymer current limiter immediately upon separation of the second contacts. A means for enhancing the dielectric strength across the second pair of open contacts prevents an arc strike from shunting out the polymer current limiter during a high available short circuit.

摘要： A blocking apparatus for blocking a contact structure from closing in a circuit breaker (10) is provided. The apparatus includes a link (182) extending from the circuit breaker and connected to amovable contact (46) arm. The contact structure, being operated by an operating mechanism (28), remains in a separated position even when the operating mechanism (28) is in the 'ON' position due to the connection with the link (182) of the blocking apparatus. A realease assembly (184) releases the link (182) when it is desired to close the movable contact (46) arm.

摘要： A return spring mechanism (302) is arranged to operate with a circuit breaker operating mechanism (32) during a trip condition. The circuit breaker operating mechanism (32) is movable between a tripped position, a reset position, an off position and an on position. The return spring mechanism (302) is attached to the exterior of the circuit breaker frame (86) and includes a return spring (288) with a fixed end (304) attached to the frame (86). When the circuit breaker (20) is tripped, the return spring mechanism (302) operates to provide an additional force to the handle yoke (88). The additional force applied by the return spring (288) is predetermined to position the handle yoke (88) intermediate to the handle yoke (88) positions when the circuit breaker (20) is off and on. Thus, the movement of the handle yoke (88) to the intermediate position provides clear indication that the circuit breaker (20) is in the tripped condition.

摘要： A circuit breaker operating mechanism comprises a movable handle yoke, a mechanism spring extending in tension from the handle yoke to a pin, and a lower link extending from the pin to a crank operably connected to a contact arm bearing a movable contact. The crank is a positionable in open and closed positions, being in an open position when the movable contact is separated from an associated fixed contact and being in a closed position when the movable contact is mated to said associated fixed contact. The circuit breaker further comprises an interface formed on said crank and a blocking prop having a first surface that engages said interface, the first surface preventing the crank from rotating towards the closed position.
