Definitions

  • the invention relates to an auxiliary switch according to the preamble of claim 1, and an arrangement of auxiliary switches and service switching devices in an installation distributor.
  • Such auxiliary switches which are attached to the broad side of an electrical service switching device, serve as a signal or as a control switch and have terminals for incoming and outgoing conductors and in between at least one changeover switch whose movable contact piece between two fixed contact pieces is movable back and forth, depending on the switching position the installation device to which they are assigned.
  • About special coupling means arranged in the auxiliary switch switching mechanism is driven, whereby the movable contact piece between its two end positions is reciprocated.
  • Auxiliary switches are often mounted in an array of installation devices together with several service switching devices and possibly also with several other auxiliary switches together on a standard profile support rail and used as installation equipment network in distribution boards.
  • auxiliary switch Today known auxiliary switch have several terminals for incoming and outgoing conductors, the terminals for incoming and outgoing conductors are often arranged together on a narrow side. That's how it is EP0815576 an auxiliary switch known, the total 2 access and 4 outgoing terminals au utilizat, with one access and 2 outgoing terminals are arranged on each narrow side of the auxiliary switch. A similar terminal arrangement is also available in an auxiliary switch EP 0303965 known.
  • Electrical service switching devices have on at least one of its narrow sides a parallel to the mounting plane extending terminal, which is accessible via an access opening and in the example, a busbar or a busbar arrangement can be used as a cross-wiring. In this case, installation switching devices are known in which such terminals are arranged on both sides.
  • EP 0303965 is a composite of an auxiliary switch with several service switching devices on a standard profile support rail disclosed.
  • the access openings to the input or output terminals of the auxiliary switch are partially in line with the access openings to the terminals of the installation switching devices.
  • a common busbar or busbar assembly as used for cross wiring of service switching devices, consists essentially of an elongated conductor, which are arranged at regular intervals perpendicular to the longitudinal direction facing, short conductor pieces, which are all in a common plane, so that in total the busbar has a comb-like appearance.
  • the distance between the repellent conductor pieces corresponds to the locking dimension or the module width of the installation switching devices. If several service switching devices are arranged side by side in a distribution box on a standard profile mounting rail, the simultaneous connection of the terminals of all the installation switching devices can be made by simply inserting the busbar into the adjacent terminals of the installation switching devices.
  • auxiliary switch of the currently known type such as from EP 0303965 or EP 0815576 known, appropriate, so this is no longer possible because the auxiliary switches are the conductor pieces of the busbar in the way.

  • the access clamp is located in the area of a narrow side and the outgoing terminals are in the area of the other narrow side.
  • the outgoing terminals are parallel to the adjacent narrow side and the access openings for insertion of the conductors are also arranged on the narrow side and from the mounting side of one another, wherein the fastening side closer located, the rear access opening associated outlet terminal occupies a greater distance from the narrow side than that of the further away from the mounting surface, front access port associated outlet terminal.
  • the auxiliary switch housing has in the area between the attachment side and the access or exit terminals on the rear narrow sides in this merging, parallel to the mounting plane toward the housing center extending recesses, so that when lining up the auxiliary switch with other service switching devices terminal lugs of cross-wiring busbars other service switching devices can be accommodated in the recesses.
  • the outgoing conductor can be first inserted into the rear access opening and clamped there; the introduction of the outgoing conductor in the front access opening is no longer hindered by the rear outlet conductor; the outlet ladder in the front access opening is always visible during assembly.
  • the input and output terminals of the auxiliary switch are thus according to the invention so that when common mounting several auxiliary switch with service switching devices on a standard profile support rail, the input and output terminals of the auxiliary switch in one Line are parallel to the mounting plane, and the input and output terminals of the service switching devices also lie on a line parallel to the mounting plane, the line of the terminals of the auxiliary switch and the line of the terminals of the service switching device at a distance from each other.
  • the gist of the invention is that the supply and / or outgoing terminals with the associated access openings of the service switching devices are in a line parallel to the mounting plane that the Zuund / or output terminals with the associated access openings of the auxiliary switch lie on a line parallel to the mounting plane, and that the line of the terminals of the auxiliary switch and the line of the terminals of the service switching devices have a distance from each other.
  • the auxiliary switch housing has at the rear narrow sides in this merging, parallel to the mounting plane, recesses whose distance from the mounting side corresponds to the distance to take the cross-wiring busbars for associated service switching devices in an installation distribution.
  • Fig. 1 has an auxiliary switch or signal switch, which can be attached laterally to a circuit breaker or a residual current circuit breaker, a housing 11 whose outer contour corresponds to the outer contour of the service switching device. It has a T-shaped contour with a base 12 and a web 13. The web 13 is located on the front side of the auxiliary switch 10.
