  • the circuit board 2 essentially forms a bottom section of the respective cover hood 16.
  • the circuit board 2 has a fastening structure 14a in the form of two projections 14a.
  • the respective cover 16 has counter-fastening structures 14b corresponding to these fastening structures 14a in the form of through openings on.

  • the third exemplary embodiment of the electrical tap 1 has a connecting device in the form of a plug 9 for inserting a corresponding mating device in the form of a socket 22 of the cabling 19. These are in the in the Fig. 13 In the arrangement shown, the electrical taps 1 are electrically connected to one another by means of the cabling 19, the cabling 19 in turn being connected to measuring and/or evaluation electronics 20. For reasons of clarity, the Fig. 15 the plug 9 is not shown.
  • the electrical taps 1 serve to supply power to the measuring and/or evaluation electronics 20, with the measuring and/or evaluation electronics 20 in turn receiving a measurement signal from current transformers 21.
  • the measuring and/or evaluation electronics 20 thus serves to measure the current flowing through the switching edge 13, for example in order to determine power consumption.
