Definitions

  • the invention relates to a residual current circuit breaker according to the preamble of claim 1.
  • Residual current circuit breakers have as internal components a transducer system comprising a summation current transformer, primary windings and a secondary winding, the primary windings being formed by phase conductors drawn through the transformer plus neutral conductors.
  • phase conductors and the neutral conductor are connected in the known residual current circuit breakers at opposite ends with terminals, which are generally designed as screw terminals.
  • the network conductor can be connected via plug contact pieces with corresponding line elements in a control panel.
  • the object of the invention is to provide a residual current circuit breaker which is easier to install in an installation system.
  • the residual current circuit breaker can be latched onto a top hat rail, which is mounted on a Stromverteilschienenan angel having at least one opening into which engages the at least one plug contact in snapped condition that the plug contact Z-shaped and formed in a Guide recess is held in the lower housing part of the residual current circuit breaker, wherein a shoulder is arranged in the lower housing part, which runs parallel to the bottom surface of the residual current circuit breaker and is seated on the crossbar of the Z-shaped plug contact.
  • the document DE 14 63 116 A shows no residual current circuit breaker.
  • the plug contact can project out of the ground in such a way that the surface of the plug contact runs parallel to the narrow side surfaces of the residual current circuit breaker. It is also possible, by suitable Umknickung the plug contacts form so that their plane parallel to the broad side surfaces of the residual current circuit breaker.
  • Fig. 1 shows a residual current circuit breaker 10, which has a housing lower part 11 and a housing upper part 12, wherein the lower housing part approximately at its center in the bottom region has a recess 13, on which a fixed nose 14 and a movable nose 15 are arranged, with which Residual current circuit breaker is snapped onto a DIN rail 16, which is mounted on a current distribution busbar assembly 17 shown schematically.
  • the housing of the residual current circuit breaker has an opening 27 in the form of a rectangular slot which includes the plug contact 26.
  • a total of two plug contacts are provided; the parallel and next to the plug contact 20 protrudes with its plug contact 28 through a slot-shaped opening 29 also out of the bottom side of the residual current circuit breaker.
  • the two plug contacts 26 and 28 lie in a plane which runs parallel to the longitudinal extent of the DIN rail 16 and engage in corresponding openings 30 in the busbar distribution 17.
