Definitions

  • the invention relates to an electrical, designed for low voltage switching device, in particular circuit breaker or contactor, with at least one device for arc extinguishing according to the preamble of claim 1.
  • the housing and the lid are equipped with guiding and holding elements for both cooling plates and splitter stacks.
  • This otherwise otherwise identical switching devices can be optionally equipped with arc quenching devices in the form of cooling plates or in the form of splitter plate.
  • arc quenching devices in the form of cooling plates or in the form of splitter plate.
  • An advantageous embodiment of the invention is to set out the quenching plates by inner walls and formations of the housing and held down first holding elements of the lid. Another embodiment is to set the splitter stack by second holding elements of the lid.
  • An expedient design is to arrange the guiding and holding elements for the cooling plates and those for the splitter stack in succession, the guide and holding elements for the cooling plates closer to the switch contacts, while the guiding and holding elements for the splitter stack are closer to connection contacts.
  • Fig. 1 are the upper part of a multi-part housing 2 and the housing 2 occlusive two-part cover 4 of an electrical switching device, such as a three-pole contactor shown.
  • two busbars 6 are fixed with externally accessible connection contacts 8.
  • the busbars 6 extend into switching chambers 10 which are bounded laterally by inner walls 12 formed in the housing 2. Switching chamber side, the busbars 6 are provided with fixed switch contacts 14 which cooperate in a known manner with not shown movable switch contacts in the form of contact bridges.
  • each switching chamber 10 is an arc quenching device either in the form of a U-shaped cooling plate 16 or in the form of a splitter stack 18 from spaced stacked quenching plates 20 can be used.
  • each switching chamber 10 the mounting position of the cooling plate 16 and the mounting position of the arc splitter stack 18 extend one behind the other with respect to the longitudinal direction of the respective switching pole. In this case, the mounting position of the cooling plates 16 is closer to the fixed switching contacts 14, however, the mounting position of the arc splitter stacks 18 closer to connection contacts. 8
  • the cooling plates 16 are laterally guided with their outer legs 22 of the inner walls 12 and positioned by their cover 4 facing away from end faces 24 in pocket-like formations 26 in the bottom 27 of the housing part of the housing 2 shown in the correct position.
  • first holding elements 28 are formed, which hold down the cooling plates 16 in its mounting position and lock with the lid 4.
  • FIG. 5 are the splitter stacks 18 with one side force and / or form-fitting in pocket-like second holding elements 30 of the lid 4 fastened. After placing the lid 4 on the housing 2, the splitter plate 18 are locked between the inner walls 12 and the bottom 27 of the housing 2 and the lid 4 in its mounting position.
