  • the electrical apparatus has a different width and / or a number of different poles, for example a four-pole four-width device comprising four terminals at the top and four terminals at the bottom.
  • connection terminals 22, 23, 26 and 27 are shaped differently, for example with a spring for clamping the bare end section of an electric cable or the tooth of a horizontal distribution comb.
