Busbars (overview)
With the help of the following tables, the required busbar lengths between two adjacent
panels each can be determined by means of the panel width and the arrangement of the
bushings at the switching-device vessel.
If a dummy panel is installed between the switchgear panels, a busbar that is longer by the
width of a dummy panel must be installed (+300 mm or +600 mm).
The busbar lengths for the provided panels can be found in the order documentation.
