Catalogue numbers
The bars are secured by insulated supports attached to
the framework.
The tables opposite indicate:
b the number and size of the bars to be used,
depending on the permissible current level in the
busbars
b the number of busbar supports for each type of
framework, depending on:
v the size of the busbars
v the rated short-time withstand current Icw.
For more information on busbar calculations, see
DESW016.
The modularity of the busbar is 3 modules.
