Product Description
Overview
The KUPO K-LOK 400 A Male 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 °C, 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, tool-free design enables rapid field assembly and disassembly, while full interoperability with standard CAM-type connectors ensures seamless integration into existing power distribution systems.
Key Features
- Non-conductive POM (Polyoxymethylene) retaining screw locks the brass contact firmly in position, eliminating accidental current paths for safer operation
- POM insulation sleeve adds heat resistance and structural strength to the contact assembly
- Ribbed Santoprene TPV housing provides a secure, slip-free grip even when wearing work gloves
- Alignment arrow ensures correct orientation for fast, error-free mating every time
- Santoprene TPV housing rated to 105 °C withstands demanding site conditions and extreme temperatures
- Brass contacts deliver reliable, low-resistance electrical connections for sustained high-current loads up to 400 A
- Double set screw termination accommodates #6 AWG (American Wire Gauge) to 4/0 AWG conductors with redundant cable retention
- Universal CAM-type compatibility integrates seamlessly with existing power infrastructure from multiple manufacturers
- UL / UL / cUL Listed ensures compliance with North American safety standards

Frequently Asked Questions
What is KL-400LMW and what is it designed for?
KL-400LMW is a KUPO K-LOK 400 A single-pole male inline cable connector with a white housing, rated for 600 V AC/DC maximum. It is engineered for heavy-duty temporary power distribution in entertainment, industrial, and event production settings. The white color coding aids rapid phase identification on the job site.
What wire sizes does KL-400LMW accept?
KL-400LMW accommodates conductors ranging from #6 to 4/0 AWG. The brass contact assembly ensures reliable electrical performance across this full conductor range, supporting up to 400 A at 600 V AC/DC.
Which electrical phase does the white color represent on KL-400LMW?
White is universally recognized in North America as the Neutral conductor per NEC conventions. Using a dedicated white connector for neutral runs eliminates guesswork during setup and teardown, reducing the risk of miswired circuits. Having a dedicated white connector in your inventory means phase assignments are physically enforced, minimizing the chance of cross-phase connection errors.
How does KL-400LMW protect against electrical hazards?
KL-400LMW 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 °C resists heat and impact, brass contacts minimize resistive heating, and the design meets UL 1691 safety requirements under UL / UL / cUL Listed E332947. The UL Enclosure Types 3R rating also provides protection in wet or outdoor conditions.
Is KL-400LMW compatible with other CAM-type connectors?
Yes. KL-400LMW 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.
