Product Description
The KUPO K-LOK 400A Female Line Connector is engineered for heavy-duty reliability and safety in high-current temporary power distribution. Featuring a Santoprene TPV (Thermoplastic Vulcanizate) housing rated to 105 degrees Celsius, brass contacts for superior conductivity, and a non-conductive POM (Polyoxymethylene) retaining screw that eliminates accidental current paths, this connector delivers the mechanical strength and electrical performance demanded by large-scale entertainment productions and industrial applications handling up to 400 amperes. The modular design enables rapid field assembly and disassembly, while full interoperability with standard CAM-type connectors ensures seamless integration into existing power distribution systems.

Frequently Asked Questions
What is KL-400LFG and what is it designed for?
KL-400LFG is a KUPO K-LOK 400A single-pole female inline cable connector with a green housing, rated for 600V AC / 250V DC maximum. It is engineered for heavy-duty temporary power distribution in entertainment, industrial, and event production settings. The green color coding aids rapid phase identification on the job site.
What wire sizes does KL-400LFG accept?
KL-400LFG accommodates conductors ranging from #6 to 4/0 AWG (UL evaluated with 4/0 AWG). The brass contact assembly ensures reliable electrical performance across this full conductor range, supporting up to 400A at 600V AC / 250V DC.
Which electrical phase does the green color represent on KL-400LFG?
Green identifies the equipment ground conductor in North America. Under IEC conventions, protective earth is green-yellow. Ground integrity is critical for personnel safety, and a distinct green connector ensures the safety earth is never confused with a current-carrying phase. Having a dedicated green connector in your inventory means phase assignments are physically enforced, minimizing the chance of cross-phase connection errors.
How does KL-400LFG protect against electrical hazards?
KL-400LFG incorporates multiple safety features: the non-conductive POM retaining screw prevents accidental current paths through the housing, the Santoprene TPV (Thermoplastic Vulcanizate) housing rated to 105 degrees Celsius resists heat and impact, brass contacts minimize resistive heating, and the design meets UL 1691 safety requirements, UL Listed under UL File E332947. The Type 3R rating (when mated) means the connector is suitable for outdoor use, with a degree of protection against rain, sleet and external ice formation.
Is KL-400LFG compatible with other CAM-type connectors?
Yes. KL-400LFG follows the universal CAM-type single-pole connector standard and intermates with CAM-type connectors from all major manufacturers. This cross-brand compatibility means you can integrate K-LOK connectors into existing power distribution systems without replacing your entire inventory.
What housing material is used in KL-400LFG and why does it matter?
KL-400LFG uses a Santoprene TPV (Thermoplastic Vulcanizate) housing rated to 105 degrees Celsius. Santoprene TPV combines the flexibility of rubber with the processing advantages of thermoplastic, delivering excellent chemical resistance, UV stability, and durability under repeated mechanical stress - exactly what professional power connectors face on tour and on set.
