Definitions

  • the invention relates to a combined residual current circuit breaker and circuit breaker, the individual poles of which are assigned to magnetic triggers for short-circuit tripping and which works with an electronic amplification for tripping in the event of a residual current.
  • an additional relay is required to trigger in the event of a fault current, which is controlled by an electronic amplifier.
  • a circuit breaker can then either open all switch contacts via a switch lock or act on a pair of switch contacts and open the switch contact pairs of the other poles via a mechanical coupling.
  • further components are required for the action on the switch lock or for the coupling.
  • Such measures also require additional space, which is reflected in more complex housings.
  • the invention has for its object to develop a combined circuit breaker of the type described so that you get by with fewer components and less space.
  • the magnetic release is provided with two windings: a first winding which is connected to the line of the waking conductor is switched on and a second winding, which is connected to the amplifier output.
  • a first winding which is connected to the line of the waking conductor is switched on
  • a second winding which is connected to the amplifier output.
  • the magnetic release 2 is provided with two windings, a first winding 6, which is connected to the line of the conductors to be monitored, the outer conductor 3 and the neutral conductor 4.
  • a second winding 7 of the magnetic release 2 is connected to the amplifier output 18.
  • the armature 9 of the magnetic release 2 is in engagement with a switching lock 10 via connecting means 11.
  • the switch contact devices 12 and 13 are opened via the connection 11.
  • Each of the switch contact devices can have a fixed contact piece and a movable contact piece.
  • a single-pole circuit breaker illustrates outer conductor 3, to which a phase is applied on the network side.
  • the excitation in the first winding 6 triggers the magnetic release 2 and in the event of a fault current, the excitation in the second winding 7.
