Frequently Asked Questions
KL-400SFY FAQ
Who should use KL-400SFY and why?
Lighting technicians, electricians, and power distribution professionals working with 400A temporary power systems will benefit from KL-400SFY. Its yellow housing provides instant visual phase identification, while the Santoprene TPV (Thermoplastic Vulcanizate) housing rated to 105 degrees Celsius ensures durability in demanding field conditions.
What voltage and amperage is KL-400SFY rated for?
KL-400SFY carries a maximum rating of 400A and 600V AC/DC. It accepts wire gauges from #6 to 4/0 AWG, making it suitable for the conductor sizes typically used in 400-amp power distribution circuits.
Why choose the yellow version of the K-LOK 400A female panel mount receptacle?
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. Choosing KL-400SFY in yellow ensures your power distribution system follows established color conventions, speeding up setup and reducing wiring errors.
Is KL-400SFY UL listed and what does that mean?
Yes. KL-400SFY carries cRUus listing (both UL and cUL) under File Number E332947, meaning it has been independently tested and certified to UL 1691 safety standards by a Nationally Recognized Testing Laboratory. This certification is required for professional power distribution in most North American jurisdictions.
What industries commonly use KL-400SFY?
KL-400SFY is widely used in industrial temporary power connections for manufacturing and processing facilities. Its 400A / 600V AC/DC rating, combined with CAM-type universal compatibility and yellow phase coding, makes it a versatile choice across the entertainment, construction, and industrial sectors.
How is KL-400SFY installed in a panel or enclosure?
KL-400SFY mounts directly to power distribution enclosures, distro boxes, and panel assemblies using its threaded stud connection and dedicated mounting holes. Once secured, the connector provides a permanent, vibration-resistant termination point that mates with standard CAM-type inline connectors.
