  • the third housing section 7 has a stop for the further processing component 10, this stop preventing further insertion of the further processing component 10.
  • the further processing component 10 embodied as a measuring board has a printed circuit board, the printed circuit board having a main extension area, with a normal vector 29 of the main extension area running in the transverse direction Y of the switching device 1 .
  • the further processing component 10 has a plurality of communication interfaces 23 accessible from the front side 3 of the switching device 1, the third housing section 7 having front openings for this purpose.
  • the transfer component 11 and the sensor component 9 each have a circuit board, with an assembly side 16 of the circuit board facing away from the sensor component 9 of the switching device 1 and an assembly side of the circuit board facing the transfer component 11 of the further processing component 10 .
  • the printed circuit boards of the sensor component 9, the transfer component 11 and the further processing component 10 are each a single-sided printed circuit board.
  • all components of the sensor component 9, in particular the current transformer 17 and the voltage taps 22, which are used to contact the input current conductor 15, are mechanically connected to the printed circuit board of the sensor component 9 and can therefore be handled as a unit.
  • the sensor component 9 and the transfer component 11 are electrically connected to one another via a flexible cable 30 .
  • the two printed circuit boards of the sensor component 9 and the transfer component 11 are offset from one another in the vertical direction Z.
  • the printed circuit board of the sensor component 9 is arranged closer to the front side 3 of the switching device 1 than the printed circuit board of the transfer component 11.
  • the transfer component 11 has a first connection device, not shown in detail in the figures, this connection device being formed by contacting surfaces of the printed circuit board in the present case, and the further processing component 10 has a second connection device 14, this connection device 14 being formed in the present case by a plurality of spring contacts.
  • the first connecting device and the second connecting device 14 can be electrically coupled to one another in order to establish an electrical connection between the transfer component 11 and the further processing component 10 by electrically coupling the first connecting device to the second connecting device 14 when mechanically connecting the second housing section 6 and the transfer component 11 arranged therein with the third housing section 7 and the further processing component 10 arranged therein.
  • the connecting device 14 is formed on a side of the further processing component 10 which faces the second housing section 6 .
  • the first housing section 5 has three bearing means 21, with these bearing means 21 being essentially circular-cylindrical and each having a through-opening 20 in the respective current transformer 17 and enforce the circuit board.
  • a copper roller 36 is arranged on the respective bearing means 21 in such a way that the bearing means 21 passes through the copper roller 36 .
  • the housing 5, 6, 7, 8 of the electronics module 2 has two cover parts 8 which are detachably connected to the rest of the housing 5, 6, 7 on the rear.
  • the cover parts 8 are connected to the rest of the housing, specifically the first housing section 5 and the second housing section 6, by means of separate connecting means designed as screws. It is quite conceivable that the screws also serve to fix the position of the printed circuit board of the sensor component 9 or the printed circuit board of the transfer component 11 .
  • the third housing section 7 can also be detached from the rest of the device when the switching device 1 and electronic module 2 are in the connected state, as is shown in FIG 12 is shown.
  • the loosening takes place in such a way that, after loosening the connecting means, the third housing section 7 only has to be moved in the direction of the arrow 32, thus counter to the vertical direction Z.
  • a connection takes place correspondingly in the opposite direction.
  • the third housing section 7 must first be moved in the direction of arrow 33, i.e. in the direction of the front side 3, in order to release the third housing section 7 and then the third housing section 7 must be moved in the direction of arrow 34, i.e. in the longitudinal direction X.
  • a connection takes place correspondingly in the opposite direction.
