20090255789 | DRAW OUT CIRCUIT BREAKER ASSEMBLY HAVING A TELESCOPIC RACKING HANDLE - A draw out circuit breaker assembly which includes a draw out circuit breaker having a plurality of contacts configured for connecting and disconnecting an electrical power source to an electrical load, a breaker cassette including a draw out support plate housing operational components of the draw out circuit breaker, and a port, and a collapsible telescopic racking handle stored collapsed in the port after the draw out circuit breaker is racked into the breaker cassette. | 10-15-2009 |
20090255791 | SYSTEM AND METHOD FOR INDICATING A POSITION OF AN ELECTRICAL DISTRIBUTION DEVICE - A system for indicating a position of an electrical distribution device configured to be racked into an electrically connected condition within an enclosure and racked out to an electrically disconnected condition via a racking mechanism is disclosed. The system includes a rotating indicator having at least a first position and a second position, the first position indicating the connected condition, and the second position indicating the disconnected condition, the indicator operably connected to the racking mechanism to rotate the indicator in response to movement of the racking mechanism between at least the connected condition and the disconnected condition. The system also includes a biasing device to bias rotation of the indicator toward the first position when the racking mechanism is in the connected condition and to bias rotation of the indicator toward the second position when the racking mechanism is in the disconnected condition. The system further includes a first mechanical stop to hold the indicator at the first position when the racking mechanism is in the connected condition, and a second mechanical stop to hold the indicator at the second position when the racking mechanism is in the disconnected condition. | 10-15-2009 |
20100072044 | CIRCUIT BREAKER UNITARY CURRENT PATH - A unitary current path structure for a circuit breaker is provided. The unitary current path structure includes a terminal portion that is configured to couple with an electrical circuit. A flexible portion is coupled to the terminal portion. A movable portion is coupled to the flexible portion. The unitary current path structure is fabricated from a plurality of sheets stacked in a laminate arrangement. The terminal portion and movable portion are formed through a solidification process. | 03-25-2010 |
20130192965 | Override Device For A Circuit Breaker And Methods Of Operating Circuit Breaker - An override device is described for use with a coupler of a circuit breaker. The override device comprising a cam member coupled to the coupler. The cam member comprising a slot. The override device also including an actuator coupled to the cam member and configured to move the cam member between an over-current protection position and an over-current relay override position and a push member coupled to the coupler. The slot configured to guide the push member to a first position when the actuator moves the cam member to the over-current protection position. The slot further configured to guide the push member to a second position when the actuator moves the cam member to the over-current relay override position to permit current flow through the circuit breaker. | 08-01-2013 |
20140090963 | SHUTTER LOCKING MECHANISM FOR CIRCUIT BREAKER ASSEMBLY - In one embodiment, a shutter lock assembly for a circuit breaker cassette having a shutter coupled to a shutter rod is provided. The shutter lock assembly includes a lock plate assembly configured to couple to the circuit breaker cassette and an actuation mechanism having a first end coupled the lock plate assembly. The actuation mechanism is configured to actuate the lock plate assembly to lock the shutter of the circuit breaker cassette in a closed position. | 04-03-2014 |
