Other Power Busbar
Compact (Sandwich) Busbar❯
200–6300 A · space-saving · IP54. A compact sandwich bus duct built from high-conductivity copper or aluminium conductors and insulation, for efficient high-current distribution in the tightest spaces.
Air-Insulated Busbar❯
Air + slot insulation · best heat dissipation · lowest cost. Air-insulated bus duct uses air with slot insulation between conductors; natural convection gives the best heat dissipation of the three types at the lowest cost.
