ABSTRACT:
Connecting bars for electrical appliances and devices, for different nominal currents, are configured in such a way that they are hollow. They may have only one or more than one cavity. The connecting bars have the same outer cross section for all current intensities, have different wall thicknesses, and consequently have differently sized cavities, for different current intensities. Consequently, the lead-through openings for the connecting bars in the respective switch housings of a type series can all be configured identically, corresponding to the dimensions for the connecting bars of the maximum current intensity.
