20090188893 - Devices, systems, and methods for managing a circuit breaker: Certain exemplary embodiments can provide a system, which can comprise a wafer that defines an opening. The wafer can be adapted to be operatively installed between a mechanical portion of a circuit breaker and an electronic portion of the circuit breaker. When installed, the wafer can be adapted to receive... Agent: Siemens Corporation Intellectual Property Department

20090179009 - Switching device, in particular a power switching device, having two pairs of series-connected switching contacts for interrupting a conducting path: A switching device, in particular a power switching device, has two pairs of series-connected switching contacts for interrupting a conducting path and at least one quenching packet, disposed near the pairs of switching contacts, for quenching the arcs occurring when the conducting path opens. The pairs of switching contacts are... Agent: Siemens Corporation Intellectual Property Department

20090179010 - Ablative-based current interrupter: Apparatus for interrupting an electrical current between two contacts, such as a first contact and a second contact, is provided. The first and second contacts are separable away from one another to interrupt electrical current flowing between the contacts. An ablative chamber is disposed around the contacts. The chamber includes... Agent: General Electric Company Global Research

20090179011 - Ablative-based multiphase current interrupter: A multiphase current interrupter is provided for interrupting a phase current between two contacts in an electrical phase. The current interrupter includes a first ablative chamber disposed around contacts for a first electrical phase. The first chamber has an ablative material thereon that causes a shock wave when an electrical... Agent: General Electric Company Global Research
