Patent number: 10804045Abstract: A circuit breaker is disclosed for interrupting an electrical circuit when current limit values are exceeded. The circuit-breaker includes a current sensor for determining the electrical current flow and a control device. When current limit values are exceeded, the electrical circuit is interrupted. A first current limit value, when exceeded, results in an immediate interruption and a second current limit value, when exceeded, results in a time-delayed interruption, such that the second interruption time reduces as the current increases. Only one control element is included for setting a current limit value. The element defining the second current limit value is included for the time-delayed interruption of the electrical circuit. The other parameters are either set in a fixed manner and/or are related to the settable second current limit value.Type: GrantFiled: November 26, 2015Date of Patent: October 13, 2020Assignee: SIEMENS AKTIENGESELLSCHAFTInventors: Henry Franke, Bernd Schwinn, Michael Strassburger
