Our K SERIES busbars are available from 800 A up to 5000 A and are appropriated for power transportation and distribution in commercial and industrial buildings even in restricted spaces. This Busbar trunking system is compact and can be installed edgewise, flat or vertically. K SERIES busbars can be supplied with aluminum or copper conductors. The conductors are insulated with suitably pre-shaped, self-extinguishing V TM-0 halogen free polyester double film, in thermal class B complying with EN 60695-2 -10. The standard protection degree is IP42 and can be increased up to IP55. The aluminum housing provides protection and mechanical seal of the conductors. The matte black painting increase the heat dissipation along the line. The standard length of the straight element is 4 meters to minimize the number of joints and in consequence the installation time. On request can be supplied any other custom size.
