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-400LFY and what is it designed for?
KL-400LFY is a KUPO K-LOK 400A single-pole female inline cable connector with a yellow 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 yellow color coding aids rapid phase identification on the job site.
What wire sizes does KL-400LFY accept?
KL-400LFY 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 yellow color represent on KL-400LFY?
Yellow identifies Phase A (L1) under China's GB 50303 standard and is also used for specialty marking in some North American installations. Its high-visibility color makes it an excellent choice for circuits that need to stand out for safety or identification purposes. Having a dedicated yellow connector in your inventory means phase assignments are physically enforced, minimizing the chance of cross-phase connection errors.
How does KL-400LFY protect against electrical hazards?
KL-400LFY 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-400LFY compatible with other CAM-type connectors?
Yes. KL-400LFY 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.
How do you assemble KL-400LFY in the field?
KL-400LFY features a modular design that enables rapid assembly and disassembly on site. Strip the cable, insert it through the housing, secure it with the double set screw termination, and lock the brass contact in place with the non-conductive POM retaining screw. The alignment arrow ensures correct orientation every time.
