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

Busbar supports<br />
Two fixed supports for 700 mm wide frameworks and one fixed support for 300 mm<br />
wide frameworks are mandatory. If more supports are required, use free supports.<br />
