The table opposite indicates:
b
the catalogue numbers of the bars to be used,
depending on the permissible current level in the
busbars
b
the number of supports required, depending on the
rated short-time withstand current (Icw in kA rms / 1
second).
Above 1600 A, the busbars must be doubled and
installed in two busbar sections, side by side. In this
case, they must be interconnected by three
equipotential links.

The permissible current values for the busbars are given for an ambient temperature of
35°C around the switchboard.
The bottom support also maintains the bars in position.
Each catalogue number represents one bar.
