Wohner Flexible Copper Busbar Plain Insulated 547A Model# 01255
Model# 01255
flexible copper busbar, plain, insulated
6x 24 x 1
547 Ampere, length 2 m
Advantages of the product
The laminated Cu busbars considerably reduce the effort of connecting busbars. The bending devices required for solid copper busbars are unnecessary. The 2mm-thick insulation means that no additional covering is required.
