Definitions

  • the invention relates to a residual current circuit breaker on whose base summation current transformers, triggers and switching lock are arranged and whose base receives switching contacts actuated by a switching shaft.
  • Such residual current circuit breakers are on the market.
  • Residual current circuit breakers have become increasingly compact and smaller over the years in order to accommodate them in distributors to save space. These efforts stand in the way, inter alia, that inevitable tolerances in plastic housings require elaborate measures to avoid gaps larger than the safety regulations between the hand control lever and the housing.
  • the invention has for its object to build a compact residual current circuit breaker low and still Compensate tolerances.
  • Switching contact pieces which are each arranged on a lever that is supported in a tiltable manner, achieve a reduction in the torque required to open the contacts with respect to the switching drum. This allows the sound lock to be kept weaker and smaller.
  • the spring acting on the contact lever not only generates the contact pressure, but also serves as a switching spring.
  • the arrangement of the quenching plates under a connection terminal and by design as an assembly with the fixed contact simplifies production and saves space.
  • the quenching plates can be arranged under the connection terminal approximately parallel to the base of the residual current circuit breaker, so that blown out hot gases do not endanger the area of the connection terminal or the mounting rail under the base of the residual current circuit breaker.
  • Another important advantage is that a further penetration in the base of the residual current circuit breaker facilitates assembly and is securely closed by a specially designed sealing piece. At the same time, this sealing piece assumes the function of determining lines in an orderly manner. Short cable routes can be achieved.
  • a centering lug on the cover of the switch housing which engages between the bearing plates of the switch lock, ensures that between the manual control handle and the plastic housing, even with conventional ones Tolerances only small permissible gaps can occur.
  • the cover of the housing can in particular have a trough with a penetration for the manual actuating element of the switching lock in order to protect it against lateral interference.
  • the test button can be made flat and square due to the inventive roughening, which facilitates handling.
  • the 1 has movable switching contact pieces 1, which are each arranged on a contact lever 2.
  • the contact lever 2 is supported in a tiltable manner on the base on the supporting wall 4.
  • the contact lever 2 is on one side by a spring 5 acts, which is supported as a compression spring on the lever.
  • the switching contact piece 1 is arranged on the side of the support point.
  • the stationary contact cloth o is arranged on a running rail 7.
  • the running rail is electrically connected on one side to a connecting terminal S.
  • the running rail 7 merges into an external quenching plate or a guide plate 9 of a stack of quenching plates 10.
  • Terminal 8, track 7 and stack of fire-extinguishing sheets can be designed as an assembly.
  • the contact lever shown and other contact levers for further poles are actuated by the shift drum 13, the imaginary axis of which is designated 14, by drivers 15.
  • the torque required for the contact opening is reduced by the support of the contact lever 2 with respect to the shift drum 13.
  • a passage to the base 3 is closed by a two-part sealing piece, one part 17 of which forms a U-shaped receptacle 18 in profile. In addition to this receptacle 18 there remains a smaller penetration which is covered by a further part 20.
  • the part 20 forms a clamping shoulder 21 to the first part 17 of the sealing piece 16. Between the clamping shoulders 21 of the parts 17 and 20, lines 22 can be clamped in an orderly manner.
  • a line connection can be made in the receptacle 18 accommodate between lines 22 and 23. The lines can be clamped in the receptacle 18.
  • the line 23 is passed through the summation current transformer 24 and electrically connected to the other connection terminal 8a.
  • a customary snap bracket 26 is formed to line up on mounting rails.
  • the cover 25 forms a centering lug 26 which engages between the bearing plate 27 of the switch lock 28.
  • the switch lock 28 is only attached to its foot.
  • the switch lock 28 finds its end position by guiding on the centering lug 26. This ensures that, despite the large tolerance for plastic parts, only small defined gaps of the permissible order of magnitude between the manual actuating member 29 and the cover of the switch housing
  • the cover hood 25 forms a trough 26 with the passage for the manual actuating element 29.
  • test button 30 can be designed to be flat and square.
  • connection terminals 8 and 8a are intended for connecting the center conductor and three phase conductors.
  • the second part of the two-part sealing piece 16, the part 20, is shown enlarged in FIG. 5 in the view corresponding to FIG. 1.
  • This part too like the first part 17 of the sealing piece 16, can snap into place in the base by means of locking feet 31.
  • the locking feet 31 can be seen in Figure 7.
