20090211883 | MULTI-POLE HANDLE LOCK FOR CIRCUIT BREAKERS - A multi-pole handle lock having a base plate and movable locking plate assembly that is adapted to mount on to at least two circuit breakers. A handle restrictor plate is mounted on the base plate for translational movement while maintaining the circuit breaker handles in the same position as each other. The handle restrictor plate allows each handle to independently move to the tripped position, while allowing the restricted circuit breakers to operate as a logical group. The low profile of the plates, allows visual inspection of the handle ends to determine their tie status. | 08-27-2009 |
20100020453 | Modular Circuit Breaker - The present invention relates generally to a circuit breaker. More particularly, the invention encompasses a modular circuit breaker. The present invention is also directed to a novel a modular circuit breaker with a trip bar. The inventive two pole residential circuit breaker includes an Arc Fault and Ground Fault electronic detection system. The modular breaker design includes an electronic system used for tripping a designated mechanism pole which in turn trips the secondary mechanism pole. Electronic components are included that sense the continuous current flow through each mechanism pole simultaneously to determine when a trip event is needed. The electronic system of this invention includes a self diagnostic system with electronic visual indicators that display the method of which trip condition occurred. | 01-28-2010 |
20100085206 | Visual Indication of Fault Status, Storage and Clearance in an Arc Fault Circuit Interrupter (AFCI) - An arc fault detector includes a means for repeatedly measuring an elapsed time. The arc fault detector also includes at least one means to perform arc detection at each repeated elapsed time. Means for initiating a tripping mechanism is activated after the elapsed time. When a fault occurs, means for generating at least one fault code is activated. The fault code is stored in at least one non-volatile memory. The fault code is selected from a group consisting of an arc fault interrupt code, a ground fault interrupt code, and a push-to-test interrupt code. The arc fault detector includes at least one means to display the fault code such as at least one LED. At least a first LED indicates an arc fault interrupt code and at least a second LED indicates a ground fault interrupt code. At least a third LED indicates a push-to-test interrupt code. | 04-08-2010 |
