    摘要: A circuit breaker is equipped with both a rotary operating handle and a power unit for selective manual and motor driven operation thereof. Mechanical and electrical control elements cooperate to insure a reliable operation in both the manual and motor driven operating modes, and, as a safety measure, to provide fool-proof, visual indications of the circuit breaker condition during the progressive stages of either operating mode. The power unit utilizes a permanent magnet, DC motor for improved performance and economies in design.

    摘要: A circuit breaker includes an operating mechanism having powerful mechanism springs to achieve the requisite contact pressures for high current carrying capacity. A single crank of a rotary handle through a relatively small arc of 120.degree. resets the operating mechanism via a reciprocating slide and a latching mechanism, while loading the mechanism springs. Return of the handle to its original position shifts the line of action of the springs such as to abruptly straighten a toggle and achieve rapid closure of the circuit breaker contacts. The latching mechanism is equipped with plural circuit breaker tripping capabilities, together with a lockout and bell alarm switch accessory.

    摘要: An air circuit breaker bell alarm accessory interacts with the circuit breaker closing system to allow automatic resetting of the bell alarm module upon resetting of the circuit breaker operating mechanism. A lockout slide extends between the bell alarm module support and the bell alarm reset slide to automatically reset the bell alarm module prior to closing of the circuit breaker contacts.

    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: Remote indication of the charge state condition of the circuit breaker closing springs is provided by a remote indicating unit. The indicating unit interfaces with the circuit breaker closing assembly to actuate an electric switch in response to the position of the closing assembly. Actuation of the switch turns a on remote signal device when the closing spring is completely charged.

    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: A conversion kit in the form of a flux shifter unit that interfaces with the circuit breaker operating mechanism and is installable without dismantling the circuit breaker is proposed herein. The flux shifter unit responds to the electronic trip unit to articulate the circuit breaker operating mechanism and separate the circuit breaker contacts upon occurrence of an overcurrent condition. Tolerance take-up for various manufacture's designs is achieved by expansion springs while electrical interface with remote accessories and other electronic trip units is achieved by button-actuated switches.
