Definitions

  • the invention relates to a combination switching device with a contactor and one thereon attached thermal overcurrent relay.
  • overcurrent relays have protruding, stiff ones from a side wall Conductor pieces, which are inserted into the contactor terminals and fastened therein become.
  • the overcurrent relay is thus connected to the conductor sections and the connection terminals the contactor is fixed to the contactor. Because the ladder is constantly out protrude from the housing of the overcurrent relay, they can bend during storage, which can then lead to assembly problems.
  • the object of the invention is to provide a combination device in which these disadvantages are avoided.
  • the contactor with the overcurrent relay can be connected by means of a latching connection, and that in the overcurrent relay Current transformers are provided, through which coupling lines can be inserted, which are connected in an electrically conductive manner to terminals on the contactor.
  • the overcurrent relay in this case is a so-called electronic relay with which Overcurrents are recorded electronically here.
  • the housing of the overcurrent relay has in the side wall facing the contactor Holes that line up with the openings of the current transformers inside the overcurrent relay swear.
  • latching arms are provided on the overcurrent relay, which behind in the assembled state Snap the protrusions onto the contactor.
  • An overcurrent relay is connected to a contactor 10a, the outer housing of which is designated 11 10b connected.
  • On the inside of the side wall 12 of the contactor there are projections 13, 14 which extend vertically inwards, i.e. into the interior of the contactor, protrude.
  • There are openings in the top and bottom walls (see drawing) 15, 16 are provided, the mode of operation of which is explained below.
  • At that Contactor adjacent wall 17 of overcurrent relay 10b is one of the number of push-through lines 19 corresponding number of openings 18 are provided, behind which in each case a transducer 21 is arranged, which has an opening 21a, which with the holes 18 are aligned.
  • the push-through conductor 19 is on a connecting terminal 20 in the contactor attached, the inside of the overcurrent relay 10b end by means of a Screw connection 29 is connected to a terminal 22 which is connected to an electronic Unit 24 is connected and to a terminal, not shown runs on overcurrent relay 10b.
  • the converter 21 has a winding, not shown, the winding ends 30, 31 are electrically conductively connected to the electronic evaluation unit 24.
  • the Current flowing through conductor 19 is detected in the current transformer 21 and by the Evaluation unit 24 evaluated; when a certain current value is exceeded the contact points in the contactor are opened.
  • Latching arms 25 and 26 are formed on the wall 17, with latching lugs 27 and 28 reach behind the projections 13, 14 so that the overcurrent relay 10b on the contactor 10a can be fixed by locking.
  • the openings 15 and 16 serve that the arms 25 and 26 can bend outwards.
  • the openings through which the arms reach through, are designated by the reference numerals 32 and 33.
  • the arrangement is three-phase, so uses a connection terminal 20 for each phase, a conductor 19 and a converter 21.
