Product Description
The KUPO K-LOK 400A 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 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 does KL-400LMB do and where is it typically used?
KL-400LMB provides a safe, reliable single-pole male connection point for 400A circuits at up to 600V AC / 250V DC. As a line connector with blue color coding, it is commonly used in professional entertainment power distribution, temporary construction feeds, and industrial installations.
What are the electrical ratings of KL-400LMB?
KL-400LMB is rated for 400 amperes maximum continuous current at 600V AC / 250V DC maximum. It accepts conductors from #6 to 4/0 AWG (American Wire Gauge; UL evaluated with 4/0 AWG), with brass contacts delivering low-resistance connections for sustained high-current loads.
What does the blue housing on KL-400LMB signify?
In North America, blue designates Phase C (L3), completing the three-phase color set. Under IEC 60445, blue is reserved for the Neutral conductor - making this color essential for international projects and cross-border equipment pools. Color-coded connectors like KL-400LMB allow crews to visually verify correct phase wiring at a glance, which is especially valuable during fast-paced load-ins and load-outs.
What safety standards apply to KL-400LMB?
KL-400LMB meets UL 1691 (Single Pole Locking-Type Separable Connectors), is UL Listed under UL File E332947, rated UL Enclosure Type 3R (when mated) for weather resistance, carries a UL94 HB flame rating, and complies with RoHS hazardous substance restrictions. These certifications collectively ensure the connector is safe for professional use in entertainment and industrial environments.
Where is KL-400LMB commonly deployed?
You will find KL-400LMB in live event and touring power, film and broadcast production, trade shows, and industrial and emergency temporary power. The blue color coding and 400-amp capacity make it particularly well suited for multi-phase power distribution in professional settings.
How do you assemble KL-400LMB in the field?
KL-400LMB 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.
