Frequently Asked Questions
What kind of connector is KL-400SFO?
KL-400SFO is a 400-ampere, 600V AC/DC single-pole female panel mount receptacle (Thread-Stud Type) from the KUPO K-LOK series. Finished in orange, it belongs to the CAM-type connector family widely used across live events, film production, and temporary industrial power systems.
How much current can KL-400SFO safely carry?
KL-400SFO is designed for a maximum continuous load of 400 amperes at up to 600V AC/DC. The brass contacts and Santoprene TPV (Thermoplastic Vulcanizate) housing rated to 105 degrees Celsius work together to maintain safe operating temperatures even under sustained full-load conditions.
How does the orange color coding on KL-400SFO help on a busy job site?
On a crowded set or event site, identifying conductors quickly is a safety essential. 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. The orange KL-400SFO connector lets technicians trace circuits visually without needing to check labels or test equipment.
What safety certifications does KL-400SFO hold?
KL-400SFO is cUL Listed under File Number E332947, certified to UL 1691 - the Standard for Safety for Cam-Type, Locking-Type Separable Connectors. It carries a UL Enclosure Types 3R environment rating, HB / UL94 flame classification, and full RoHS (Restriction of Hazardous Substances) compliance.
Can KL-400SFO work with connectors from other brands?
Absolutely. The K-LOK 400A series uses the industry-standard CAM-type interface, so KL-400SFO mates directly with compatible single-pole connectors regardless of manufacturer. This makes it easy to expand or upgrade your connector stock incrementally.
What housing material is used in KL-400SFO and why does it matter?
KL-400SFO uses a Santoprene TPV (Thermoplastic Vulcanizate) housing rated to 105 degrees Celsius. Santoprene TPV delivers outstanding resistance to heat, chemicals, and UV exposure while maintaining flexibility across a wide temperature range - essential properties for connectors installed in enclosures that may face extreme operating environments.
