Busbar configuration
The bars are supported by insulating supports: 3 fixed
supports (screwed to the framework) are compulsory.
If necessary, use additional mobile supports.
The bars rest against one of the fixed supports by
means of a wedge screwed onto each bar.
The table on this page shows:
• The number and section of the bars to be used
according to the permissible current level of the
busbar.
• The number of bar supports to be installed
according to the rated short-time withstand
current (Icw en KA eff/15).
• The busbar is installed in suitable enclosures with
width 700 mm and depth 500 mm.
Busbar selection
Flat bars with width 1675 mm
Bar supports
3 fixed supports are compulsory for supporting the vertical busbars. If more than
3 supports are required, use the mobile supports (additional).
Bar wedging
A metal wedge with thickness 5 mm is screwed onto the bar.
It rests against a fixed support and wedges the bar.
Connection to a horizontal busbar, thickness 10 mm
Fixed bar support
04653.
Mobile bar support
