    摘要: An air circuit breaker ratcheting mechanism includes a ratchet and pawl whereby the closing springs charging gear is prevented from reverse rotation during the closing springs charging operation. Upon completion of the charging operation, the ratchet and pawl become disengaged from the charging gear to allow the closing springs to respond to a manual closing button depression. A holding prop within the ratcheting mechanism interacts with a roller bearing on the charging shaft to prevent reverse rotation of the charging shaft under the bias provided by the charged closing springs.

    摘要: An air circuit breaker ratcheting mechanism includes a ratchet and pawl whereby the closing springs charging gear is prevented from reverse rotation during the closing springs charging operation. Upon completion of the charging operation, the ratchet and pawl become disengaged from the charging gear to allow the closing springs to respond to a manual closing, command. An operating handle pivot assembly allows a molded plastic handle operator to be employed and the ratcheting mechanism is arranged for modular assembly during the circuit breaker manufacturing process as well as motor to manual charge conversion one site.

    摘要: An operating mechanism controls and trips a separable contact structure arranged in a protected circuit. The mechanism includes a frame, a drive member pivotally coupled to the frame, a spring pivotally connecting the drive member to a drive connector, an upper link pivotally seated on the drive connector, a lower link member pivotally coupled to the drive connector, a crank member pivotally coupled to the lower link member for interfacing the separable contact structure, and a cradle member pivotally secured to the frame and pivotally securing the upper link. The cradle member is configured for being releasably engaged by a latch assembly, which is displaced upon occurrence of a predetermined condition in the circuit such as a trip condition. The mechanism is movable between a tripped position, a reset position, an off position, and an on position. Spacers are operatively positioned between movable members, and protrusions are operatively formed on the enclosure of the contact structure. The spacers and protrusions serve to widen the stance of the operating mechanism for force distribution purposes, and also to minimize friction between movable components.

    摘要: An air circuit breaker bell alarm unit allows selection of both bell alarm accessory lock-out facility along with automatic reset function. A plunger extending from the bottom of the bell alarm accessory interacts with the circuit breaker operating components to automatically reset the bell alarm pop-up target in the early stages of the closing of the circuit breaker contacts or to lock-out the closing of the circuit breaker contacts until the pop-up target is manually reset.

    摘要: A circuit breaker cassette comprises a housing having a fixed contact, and a movable contact on a contact arm. The contact arm is positionable in a closed position and an open position, wherein the contact arm is closed when the movable contact is in contact with said fixed contact. A spring biases the movable contact arm towards the closed position A kinetic energy-absorbing stop is positioned to absorb kinetic energy of the contact arm resulting from magnetic repulsive forces forcing the movable contact and the fixed contact apart during a short circuit condition.

    摘要: An air circuit breaker bell alarm accessory interacts with the circuit breaker contact position indicator to provide local and remote indication of the occurrence of a circuit interruption. A drive pin extending from the bottom of the accessory interacts with a slot on the contact position indicator lever to prevent release of the circuit breaker closing spring until the bell alarm accessory is manually reset.
