  • Patent number: 6639168
    Abstract: 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.

  • Patent number: 6590482
    Abstract: A circuit breaker operating mechanism for separating a pair of electrical contacts within an electrical circuit breaker includes a lower link operatively connected to one of the electrical contacts. An upper link includes first and second legs extending from a central portion. The first leg is pivotally secured to the lower link, and the second leg includes a cam surface formed thereon. A roller is in intimate contact with the cam surface, and the cam surface is configured such that movement of the upper link relative to the roller causes the upper link to pivot about the central portion. Pivoting of the upper link about the central portion moves the lower link causing the second contact to move away from the first contact. An operating spring is configured to provide a force for separating the electrical contacts when the operating mechanism is tripped. An operating handle includes a void disposed therein, and an end of the spring is secured to the operating handle within the void.

  • Patent number: 6479774
    Abstract: 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 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.

  • Patent number: 6459059
    Abstract: A return spring mechanism is arranged to operate with a circuit breaker operating mechanism during a trip condition. The circuit breaker operating mechanism is movable between a tripped position, a reset position, an off position and an on position. The return spring mechanism is attached to the exterior of the circuit breaker frame and includes a return spring with a fixed end attached to the frame. When the circuit breaker is tripped, the return spring mechanism operates to provide an additional force to the handle yoke. The additional force applied by the return spring is predetermined to position the handle yoke intermediate to the handle yoke positions when the circuit breaker is off and on. Thus, the movement of the handle yoke to the intermediate position provides clear indication that the circuit breaker is in the tripped condition.

  • Patent number: 6448521
    Abstract: A blocking apparatus for blocking a contact structure from closing in a circuit breaker is provided. The apparatus includes a link extending from the circuit breaker and connected to a movable contact arm. The contact structure, being operated by an operating mechanism, remains in a separated position even when the operating mechanism is in the “ON” position due to the connection with the link of the blocking apparatus. A release assembly releases the link when it is desired to close the movable contact arm.

  • Patent number: 6421217
    Abstract: An accessory includes a trip arm biased by a spring to pivot in a clockwise direction about a trip arm pivot. A latch is arranged to pivot about a latch pivot and has the trip arm acting on a latch surface on the latch to bias the latch in a counter clockwise direction about the latch pivot. An electromechanical device including a plunger acts on the latch pulling it clockwise about the latch pivot. When a signal is provided to the electromechanical device, the plunger is released allowing the trip arm to pivot clockwise about the trip arm pivot due to the spring and actuates the operating mechanism. To reset the trip arm and the latch, a reset lever is arranged to pivot about the latch pivot. The reset lever includes a tab portion configured for interfacing the operating mechanism, and a drive portion for interfacing the trip arm. This, when the operating mechanism is reset, a portion extending from an operating handle interfaces the tab portion to pivot the reset lever clockwise about the latch pivot.

  • Patent number: 6403902
    Abstract: A combination air circuit breaker bell alarm reset and lock-out accessory unit interacts with the circuit breaker closing system to prevent charging of the circuit breaker closing spring until and unless the bell alarm module has been manually reset in one option and allows automatic reset of the bell alarm module prior to charging of the closing spring in a further option. The orientation of the bell alarm module on the combination reset and lock-out accessory unit support plate determines the reset or lock-out option selection.
