Definitions

  • the invention relates to a residual current circuit breaker with a test device according to the preamble of claim 1.
  • a residual current circuit breaker is known (DE-A-2 504 007).
  • the invention has for its object to develop a residual current circuit breaker with carrier and test device, which has a particularly small space requirement with regard to the test device and the assembly.
  • This object is achieved by the characterizing features of claim 1.
  • the V-shaped spring assumes both a mechanical and an electrical function for the test device of the summation current transformer. It allows short distances to the wearer and it can be kept small. This means that a smaller carrier and a smaller housing for the residual current circuit breaker are sufficient.
  • Such a residual current circuit breaker can be built with the profile of a low circuit breaker and yet be made much narrower in the direction of a conventional mounting rail than it is wide across the rail. This advantage of the small structure is particularly evident when the fixed contact pieces are also arranged on the carrier, so that the tolerance insensitivity is further increased.
  • a V-shaped spring with a test button is known per se (DE-B-2 220 558).
  • DE-B-2 220 558 A V-shaped spring with a test button is known per se (DE-B-2 220 558).
  • the special advantages in connection with a carrier and the special structure cannot be gained there.
  • the V-shaped spring of the test device can be a helical spring with an extended end. Such a structure is particularly simple.
  • the shift drum 4 can be held with its axis on an arm of the wearer, to be positioned lying in front of the drawing plane. At its other end, it can find an abutment in the circuit boards of the key switch.
  • the switch lock 6 and the magnetic trigger 3 are fastened on a wall opposite one another on the support 5 and, below in the exemplary embodiment, the switching drum 4 for the contact system 7 is arranged transversely.
  • the summation current transformer 2 is arranged with its imaginary axis upright on the narrow side of the magnetic release 3 and switch 6.
  • the carrier 5 is angular. Its corner houses the magnetic trigger 3.
  • the carrier 5 sits on a base in the housing 1, which can be formed by projecting edges and shielding walls.
  • the base is provided with a pocket-shaped recess 8 for the switching lock 6 arranged on the outside of the angular carrier 5 (FIG. 3).
  • a partition wall can be formed between two adjacent movable contact pieces. 1, the partition is parallel to the plane of the drawing behind a contact piece 10 of the contact system 7.
  • connection terminals 11 according to FIG. 2 can be accommodated in the corners adjacent to the summation current transformer 2 on a narrow side of the housing. On the opposite narrow side, outgoing terminals 12 and a stack of fire-extinguishing plates 13 according to FIG. 1 are arranged underneath.
  • the spring 15 made of electrically conductive material is electrically connected to a phase in the residual current circuit breaker.
  • a suitable ballast resistor 17 is expediently interposed.
  • the V-shaped spring 15 is designed as a coil spring with an extended end. 1 and 2, the test circuit for the usual test device for a residual current circuit breaker is formed by a contact piece 20 which, via a contact lug 21 in the switched-on state, that is to say when the contact pieces 10 and 22 are in contact, has contact with the phase conductor which is connected to the contact piece 10 lies, produces.
  • the test circuit is further developed by a line 23 with the series resistor 17 and through the V-shaped spring 15. It is further formed by contact with the stripped area of the turn 16 of the neutral conductor.
  • 24 denotes a phase conductor of the primary winding
  • 25 denotes the secondary winding of the summation current transformer 2.
  • the housing 1 has a cap 26 which is screwed onto a lower part. On the underside of the housing 1, a snap bracket for snapping onto mounting rails is formed.
  • the snap holder is formed in the usual way by a nose 27 and by a slide 28.
