Patent number: 11017968Abstract: An electrical switch for switching an electric current is disclosed. The electrical switch includes an electronic trip unit, embodied in a bipartite fashion. A first part of the trip unit is fixedly connected to the electrical switch and includes protection functions of the electrical switch. A second part of the trip unit is embodied mountably and detachably on the electrical switch and defines the protection functions enabled for the customer.Type: GrantFiled: June 15, 2016Date of Patent: May 25, 2021Assignee: SIEMENS AKTIENGESELLSCHAFTInventors: Henry Franke, Stefan Haebel, Rainer Huentemeier

Patent number: 10250028Abstract: An electrical switch is disclosed for switching an electric current between a feed and an outgoer. The electrical switch can be mounted in a switchgear assembly and as a result electrical contact can be made with the electrical switch by a feed and an outgoer of the switchgear assembly. In one embodiment, the electrical switch includes an internal voltage tap for supplying power to a switch-internal electronics system and a changeover switch. The changeover switch adjusts the electrical connection between the feed or the outgoer and the internal voltage tap.Type: GrantFiled: May 4, 2016Date of Patent: April 2, 2019Assignee: SIEMENS AKTIENGESELLSCHAFTInventors: Henry Franke, Stefan Haebel, Rainer Huentemeier

Patent number: 10218167Abstract: A circuit breaker includes a tripping unit for interrupting an electrical circuit, and at least one current sensor for determining the electrical current flowing through the circuit breaker, connected to a control unit and configured such that the determined current is compared with current/period limit values. If a current/period limit value is exceeded, the tripping unit interrupts the electrical circuit. The current/period limit values include an adjustable first current limit value, present for a first period for an interruption; an adjustable second period, during which a second current limit value must be present to effect an interruption; and a range between the first current limit value and the second current limit value, the period decreasing with increasing current limit values in order to effect an interruption. The second current limit value can be adjusted at the circuit breaker.Type: GrantFiled: April 28, 2016Date of Patent: February 26, 2019Assignee: SIEMENS AKTIENGESELLSCHAFTInventors: Henry Franke, Wolfgang Fruth, Stefan Haebel, Rainer Huentemeier

Patent number: 9991079Abstract: A circuit breaker is disclosed, including a series circuit including a measuring unit for determining the electrical current or/and voltage of the electrical circuit, an exchangeable trip unit for determining when current limit values are exceeded, and a switching unit for interrupting the electrical circuit if current limit values are exceeded. A switch characteristic module is connected to the trip unit and stores characteristic data relating to the circuit breaker. If a trip unit used is at least exchanged for a new trip unit, the characteristic data are transmitted to the new trip unit. Data specific to the trip unit are transmitted from the trip unit and are stored in the further memory area of the switch characteristic module. If a new trip unit is used, the characteristic data and the data specific to the trip unit are transmitted to the new trip unit.Type: GrantFiled: May 5, 2016Date of Patent: June 5, 2018Assignee: SIEMENS AKTIENGESELLSCHAFTInventors: Henry Franke, Stefan Haebel, Rainer Huentemeier

Patent number: 9966754Abstract: A circuit breaker is disclosed for an electrical circuit. The circuit breaker includes a tripping unit; at least one current sensor; and an input for a signal, at which a blocking signal for a circuit breaker arranged upstream on the energy sink side, can be received. The tripping unit; at least one current sensor; and an input are all connected to a control unit. A connectable blocking function is provided. The ascertained current is compared with a first current limit value, the exceeding of which requires this first current value to be present for a first period of time in order to prompt interruption of the electrical circuit; and is compared with a second current limit value. Different periods of time need to be present to prompt interruption when the blocking function is disengaged or engaged.Type: GrantFiled: May 3, 2016Date of Patent: May 8, 2018Assignee: SIEMENS AKTIENGESELLSCHAFTInventors: Henry Franke, Wolfgang Fruth, Stefan Haebel, Rainer Huentemeier
