Publication number: 20100170876Abstract: A circuit breaker has at least one housing having at least one opening, and at least one pair of contacts located in the housing, the contacts of the pair of contacts being mobile in relation to each other for opening and closing an electric circuit. An open-pore metal foam (20) is interposed between at least one of the pairs of contacts and at least one housing opening (11), the metal foam being electrically insulated from the current-carrying elements of the circuit breaker (1). An open-pore metal foam (20), produced of a zinc base alloy or aluminum base alloy, can be used as a cooling structure for the dissipation of heat from switching gases that are produced by an electric switching process.Type: ApplicationFiled: May 28, 2008Publication date: July 8, 2010Inventors: Michael Bach, Werner Hartmann, Detlev Schmidt, Günter Seidler, Sezai Türkmen, Artur Wajnberg

Patent number: 7495190Abstract: An electrical switch is disclosed. The switch includes at least one switching contact which is held against the prestressing force of a contact force spring on a moving contact mount, and an arc quenching device, in which at least one section of the at least one contact force spring extends between side pieces of the contact mount. A device for limiting the spreading of combustion products is provided, which has an angle bracket inclined with respect to the opening direction of the moving contact mount. When the contact mount is in the open position, the bracket overhangs the at least one section of the at least one contact force spring. In order to protect the contact force springs, in particular at the end of the opening process, even better against contamination by spreading combustion products, the inclined angle bracket is seated in a prestressed manner on the side pieces.Type: GrantFiled: September 28, 2006Date of Patent: February 24, 2009Assignee: Siemens AktiengesellschaftInventors: Hans-Joachim Kuhrt, Günter Seidler
