K series busbars are appropriated for power transportation and distribution in commercial and industrial buildings. 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 we can supply any other custom size.
Main characteristics:
·Monobloc joint with predefined breaking, not requiring additional tools
·Straight elements length 4m, the customized lengths are available on request
·Distance between plug-in points 1m
·Tap off boxes from 32 up to 1250 A: plug-in type up to 400 A series, bolted type 630 – 1250A
·Completely isolated system, energized line’s live parts are not accessible
·Fire barriers with fire resistance up to 120 minutes
·High resistance to short circuit
·Protection degree up to IP55 (IP65 on request)
·Custom made elements T, Z
·Wide range of accessories to connect to transformers, generators, electric panels
Advantages: corrosion resistance, reliable monobloc joint, high thermal dissipation, lightness, multiple customizations.
