Patent number: 10056212Abstract: A residual current circuit breaker has a summation current transformer that has primary windings as well as a secondary and a tertiary winding, the secondary winding forming a circuit with an electronic trigger unit that is independent of the network voltage, and the tertiary winding forming a circuit with an electronic trigger unit that is dependent on the network voltage. The residual current circuit breaker may have an electronic control unit designed to actuate a switch upon predefinable actuation by the network voltage-dependent electronic trigger unit, and the switch, when in the actuated state, may interrupt contact of the secondary winding with the network voltage-independent electronic trigger unit and establishes contact of the tertiary winding with the network voltage-dependent electronic trigger unit.Type: GrantFiled: May 23, 2014Date of Patent: August 21, 2018Assignee: EATON INTELLIGENT POWER LIMITEDInventor: Georg Ritzinger

Patent number: 8390465Abstract: A residual-current circuit breaker includes at least one summation current transformer through which at least one first lead and one second lead of a network to be protected are guided. At least one secondary winding is arranged on the summation current transformer and operatively connected at least indirectly with at least one energy storage element. At least one discharging resistor is switched in parallel with the energy storage element. The residual-current circuit breaker has a trip element which is operatively connected with break contacts in the at least one first lead and the at least one second lead. In order to reduce unexpected cut-offs of a network to be protected, the at least one discharging resistor includes a first partial resistor, and a second partial resistor switched in series with respect to the first partial resistor, with a least one electric signaling device operatively connected, at least indirectly, with the first partial resistor.Type: GrantFiled: June 12, 2009Date of Patent: March 5, 2013Assignee: Moeller Gebaudeautomation GmbHInventors: Rainer Meisel, Georg Ritzinger

Patent number: 8315023Abstract: A residual-current circuit breaker includes a summation current transformer having a core, a first secondary winding wound onto the core, and at least one second secondary winding wound onto the core, with lines of an electric network to be protected extending through the core. A tripping apparatus is operably connected to break contacts for opening the break contacts. A first arrangement is provided for detecting alternating residual currents and connected to the first secondary winding of the summation transformer. A second arrangement is connected to the second secondary winding for detecting direct residual currents, wherein a predeterminable alternating operation of the first and second arrangements is controlled by a timer device.Type: GrantFiled: December 1, 2009Date of Patent: November 20, 2012Assignee: Moeller Gebäudeautomation GmbHInventors: Rainer Meisel, Georg Ritzinger
