20100073113 | Electromagnet Assembly Directly Driving Latch Of An Electronic Circuit Breaker - A circuit breaker includes a trip unit and an electronic fault detection unit sharing a common trip latch for causing the circuit breaker to trip upon detection of a fault by either unit. The circuit breaker has an electromagnet for causing the circuit breaker to trip upon detection of a fault by an electronic fault detection unit. The electromagnet is oriented in the housing proximal the trip latch without any components interposed between them, and directly attracts the latch. Advantageously the electromagnet orientation does not impact operation or the range of motion of the latch or other trip unit components. Advantageously the circuit breaker of the present invention does not increase the trip latch mass, its bulk swept volume through its range of motion or require additional linkage components that potentially might increase trip cycle time. In some embodiments the electromagnet core is reciprocable. | 03-25-2010 |
20110037429 | ELECTRICAL DISTRIBUTION SYSTEM RECHARGING STATION FOR ELECTRIC VEHICLES - An electric vehicle recharging station that can be readily incorporated into existing building electrical distribution systems during retrofit or new construction. The system has at least one enclosure and a vehicle charging connector. A circuit interrupter has line terminals for connection to respective first and second phases of the distribution system. A contactor relay has first and second phases coupled to the respective circuit interrupter and electric vehicle charging connector phases and separable contacts for each phase, for selective connection of electric power to the charging connector. A recharger controller is coupled to the contactor, for causing selective separation and closing of the separable contacts, so that electrical power is transferred to the electric vehicle. The recharging station system may also incorporate electric rate metering functions as well as communication capability from the controller to a remote controller. A human machine interface may be coupled to the controller. | 02-17-2011 |
