  • Patent number: 8625238
    Abstract: A ground-fault circuit interrupter has a test circuit for generating a test fault current. The test circuit includes a test button, a first test resistor, and a regulating circuit constructed to generate a test fault current with a predetermined and substantially constant value independent of an applied voltage of an electrical network to be protected. The test button, the first test resistor and the regulating circuit are connected in series between phases of the electrical network.

  • Publication number: 20120249151
    Abstract: A compact residual-current circuit breaker constructed for functional testing without any interruption of the downstream electric network includes two separate tripping circuits, wherein a first tripping circuit is independent of the mains voltage and a second tripping circuit is dependent on the mains voltage. During functional testing one of the tripping circuits the respective other tripping circuit monitors the electric network to be protected for fault currents.

  • Publication number: 20120090975
    Abstract: To increase safety when working on electrical installations, a switching device which has a first switch position and a second switch position, includes a first movable switch contact contacting a first contact part in the first switch position and a third contact part in the second switch position, and a second movable switch contact contacting a second contact part in the first switch position and a fourth contact part in the second switch position, wherein the third contact part and the fourth contact part are conductively connected with one another. The switching device can be constructed as a ground-fault circuit interrupter and/or a line circuit breaker.
