Patent number: 8749941Abstract: A residual-current circuit breaker includes at least one summation current transformer through which are guided at least one first conductor and one second conductor of an electric network to be protected. At least one secondary winding is arranged on the summation current transformer and connected in terms of circuitry to a trip element. A test circuit connects the first conductor with the second conductor and includes at least one first test resistor, a second test resistor arranged serially in relation to the first test resistor in terms of circuitry, and a test button. The second test resistor is bridged by a shunt line which is guided through the summation current transformer. Arranged in the shunt line in terms of circuitry is at least one first voltage-dependent resistor.Type: GrantFiled: March 18, 2011Date of Patent: June 10, 2014Assignee: Moeller Gebäudeautomation GmbHInventor: Gerhard Dobusch

Publication number: 20100308943Abstract: A residual-current circuit breaker has a mains voltage-independent fault current breaking and includes at least one summation current converter, through which at least one first conductor and a second conductor of a network to be protected are run. Disposed on the summation current converter is at least one secondary winding. The secondary winding in terms of the circuit design is connected to a breaker, which is operatively connected via a switch latch to break contacts in the at least one first conductor and the at least one second conductor. Further disposed on the summation current converter is a tertiary winding, which in terms of the circuit design is connected to at least one voltage-dependent resistor. In order to use a test resistor having a small size, while foregoing a switch contact in the test current circuit, the tertiary winding is configured as part of the test current circuit which includes a test sensor and a test resistor.Type: ApplicationFiled: February 2, 2009Publication date: December 9, 2010Inventor: Gerhard Dobusch
