K-LOK 400A Brown Connectors

Brown K-LOK 400A connectors identify Line 1 (L1) under the IEC 60446 standard and in North American 277/480V high-voltage systems. In the entertainment industry, brown 400A connectors appear on main feeder legs for venues and productions that follow IEC color conventions, or on 480V utility tie-ins where NEC mandates the brown-orange-yellow color scheme for higher voltage tiers. Because IEC 60446 is the dominant standard across Europe, the UK, Australia, and much of Asia, brown is the de facto L1 identifier for the majority of the global market. All K-LOK 400A brown connectors share the full 400A/600V specification with brass contacts and Santoprene body. Available in line connector, panel mount receptacle, double set screw, and threaded stud configurations.
