Definitions

  • the invention relates to a low-voltage circuit breaker with a front wall and a rear wall Housing with certain functional divisions, with the front wall and the rear wall by a vertical in the use position running joint between the front wall of the housing and the rear wall of the housing are separated.
  • circuit breakers of the circuit breaker Located between the front wall of the housing and the rear wall of the housing the circuit breakers of the circuit breaker. It is consequently required for the purpose of maintenance or repair to remove the switch contact systems from the back of the housing, to get access to the corresponding assemblies. This can be done after all screws have been removed are which the rear wall of the housing directly with the front wall of the housing and connect with the foot plates.
  • circuit breakers is the rear wall of the housing and the housing front wall in proportion large and interlocking interlocking molded plastic parts, so that there is no avoiding separation the back of the case from the case front is a relative great effort is required. With one Tilting or gluing the two parts together into one jerky movement of the back wall in relation to the front wall of the housing.
  • a low voltage circuit breaker of the ones considered here conventional design is for example in the U.S. Patent 4,764,650.
  • This low voltage circuit breaker is with a vertical joint between the front wall and the rear wall with certain functional divisions provided and shows the between those in both housing parts arranged switch elements.
  • DE-GM 296 15 162 shows a low-voltage circuit breaker with one arranged concentrically to the connecting rail Current transformer and a connection line to the overcurrent release, in which the switch rear wall by a low and pivot axis arranged in the area of the foot plates is hinged to the rear.
  • the object of the present invention is now a Danger or damage to the electrical connection lines between the current transformers in the rear wall of the housing and the electronic in front of the housing front wall Exclude tripping unit when the low-voltage circuit breaker for maintenance or repair purposes is dismantled.
  • This object is achieved in that in particular for multi-pole low-voltage circuit breakers with a housing front wall and a housing rear wall, the due to a vertical joint in the position of use are separated from each other in the bottom of the rear wall of the housing an integrated cable duct is provided, which is below the contact carrier bearings and the lower connecting rails surrounding current transformer chambers, essentially across the entire width of the low-voltage circuit breaker extends and in the direction of the front wall of the housing one or more through openings for the passage of the Connection lines between the current transformers and one front electronic release unit.
  • This Cable duct is not from other rooms of the low voltage circuit breaker cut, but forms a completely separate tunnel. It takes all the harnesses in one from the rest of the low-voltage circuit breaker in a separate room and thus avoids the risk of damage to the cables during assembly, repair and maintenance work on the switch.
  • the cable duct is closed with a cover plate that made of a thin and elastic material with sufficient Resistance to being pressed into the cable duct consists.
  • a suitable material can suitably be a hard tissue his.
  • the housing rear wall has a groove on the housing side with a groove in the Groove protruding over the entire length of the cable duct Nose provided, in which the cover plate for Closing the cable duct can be snapped into place.
  • the cover plate is preferably for assembly and disassembly provided with one or more disassembly openings.
  • the cover plate can be done with the help of these disassembly openings of tools inserted into and removed from the groove be, the nose pushing through the cover plate prevented in the cable duct.
  • FIG. 1 schematically shows a section through a low-voltage circuit breaker, in which the spatial arrangement can be seen.
  • FIG. 2 schematically shows a perspective view of a three-pole low-voltage circuit breaker from behind below, in which the open cable duct according to the invention see is.
  • Fig. 3 shows a detail of the housing-side groove for receiving the cover plate for the cable duct.
  • Fig. 1 is a low-voltage circuit breaker schematically 1 with a housing front wall 2 and a housing rear wall 3, which are separated by a joint, not shown are separated, shown in a sectional view, in the upper connecting bar 4, the lower connecting bar 5, which leads through the current transformer chamber 6, the arcing chamber 7, the switch drive 8, and the movable contact carrier 9 are shown with the movable switching contact 10 in order the spatial arrangement of the cable duct 11 according to the invention to be identified in the rear wall 3.
  • This cable duct 11 extends, as can be seen in FIG. 2 is, in the bottom 12 of the rear wall 3 of the low-voltage circuit breaker 1 below the not visible Contact carrier bearings and the lower connecting rails 5 surrounding current transformer chambers covered in the illustration 6, essentially across the full width of the low-voltage circuit breaker 1.
  • the cable duct 11 In the direction of the front wall of the housing 2, the cable duct 11 has a passage opening 13 for passing the connecting lines between the Current transformers and an electronic dashed line Trip unit 18 on.
  • This cover plate 16, which for example from Hard tissue is made for assembly and disassembly provided two disassembly openings 17.
  • the cover plate 16 can with the help of these disassembly openings 17 without the aid of Tools are inserted and removed in the groove 14, wherein the nose 15 a pushing through the cover plate 16th prevented in the cable duct 11.
