Application and installation

For electrical distribution and control panels and equipment connections. Use as an N or PE bar requires a design selected and verified by the designer.

Current capacity depends on temperature, cooling, bar arrangement and connections. Cross-section alone does not determine current capacity; check manufacturer documentation and the panel design.

Prepare and tighten aluminium contacts according to the connection manufacturer’s instructions. Use a compatible connection system for Cu–Al joints; contact paste alone does not replace proper connection selection.

A bare busbar is not insulated. Suitable supports, insulation clearances and protection against contact are required. Check short-circuit withstand.
