Collection: K-LOK 400A

K-LOK 400A is KUPO Power's heavy-duty North American single-pole cam-type connector for primary power distribution at 400A / 600V. Built to UL 1691 and CSA C22.2 No. 1691 standards with brass contacts and Santoprene (TPV) housing rated 105 degrees Celsius and UV-resistant. The 400A range is the heavy-duty companion to K-LOK 150A, used for generator outputs, primary distribution feeds, festival and touring main supply, broadcast trucks, switchgear, and any application requiring 400A continuous current per phase. Compatible with other 400A cam-type connector brands. Not intended for connection or disconnection under load.

Two panel-receptacle cable-termination styles are available: Threaded Stud (bolt-on cable lug, for permanent and semi-permanent installations) and Double Set Screw (clamp-style termination, for frequent reconfiguration in portable distribution).
