Definitions

  • the voltage supply of the control device itself is designed as an energy store, which is thus connected to the load-side current and neutral, so that it is charged only in the non-triggered state of the residual current circuit breaker.
  • the residual current circuit breaker 1 has for this purpose a measuring device 10, which taps and measures the current flowing in the current conductors L and neutral N current load side after the switching elements Sl and S2 on the conductors L and N.
  • an evaluation device 20 is provided which compares the totality of the measured currents with a reference value.
  • This evaluation device can operate, for example, according to the summation current transformer principle.
  • a shutdown device 30, as shown the switching elements Sl and S2 open, or if there is no error, the switching elements Sl and S2 keep closed. This is usually done via a corresponding relay K, which is controlled by the shutdown device 30.
