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, 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.

Frequently Asked Questions
What does KL-400LFO do and where is it typically used?
KL-400LFO provides a safe, reliable single-pole female connection point for 400A circuits at up to 600V AC/DC. As a line connector with orange color coding, it is commonly used in professional entertainment power distribution, temporary construction feeds, and industrial installations.
What are the electrical ratings of KL-400LFO?
KL-400LFO is rated for 400 amperes maximum continuous current at 600V AC/DC maximum. It accepts conductors from #6 to 4/0 AWG (American Wire Gauge), with brass contacts delivering low-resistance connections for sustained high-current loads.
What does the orange housing on KL-400LFO signify?
Orange is traditionally reserved for high-leg delta circuits and other specialty applications in North America. It provides an unmistakable visual warning that a conductor carries a voltage different from the standard phases - critical information for electricians working with delta transformer configurations. Color-coded connectors like KL-400LFO 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-400LFO?
KL-400LFO meets UL 1691 (Cam-Type, Locking-Type Separable Connectors), is cUL Listed under E332947, rated UL Enclosure Types 3R for weather resistance, carries a HB / UL94 flame class, 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-400LFO commonly deployed?
You will find KL-400LFO at work in portable power distribution for emergency and disaster-response operations. The orange color coding and 400-amp capacity make it particularly well suited for multi-phase power distribution in professional settings.
