Frequently Asked Questions

What kind of connector is KL-400SFW?

KL-400SFW is a 400-ampere, 600V AC / 250V DC single-pole female panel mount receptacle (Thread-Stud Type) from the KUPO K-LOK series. Finished in white, 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-400SFW safely carry?

KL-400SFW is designed for a maximum continuous load of 400 amperes at up to 600V AC / 250V 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 white color coding on KL-400SFW help on a busy job site?

On a crowded set or event site, identifying conductors quickly is a safety essential. 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. The white KL-400SFW connector lets technicians trace circuits visually without needing to check labels or test equipment.

What safety certifications does KL-400SFW hold?

KL-400SFW is UL Listed under UL File Number E332947, certified to UL 1691, the standard for single-pole locking-type separable connectors, and rain tested to UL 50E. It carries a UL Enclosure Type 3R (when mated) environment rating, UL94 HB flame classification, and full RoHS (Restriction of Hazardous Substances) compliance.

Can KL-400SFW work with connectors from other brands?

Absolutely. The K-LOK 400A series uses the industry-standard CAM-type interface, so KL-400SFW mates directly with compatible single-pole connectors regardless of manufacturer. This makes it easy to expand or upgrade your connector stock incrementally.

What makes KL-400SFW suitable for permanent installations?

Unlike inline connectors designed for repeated connection and disconnection, KL-400SFW is engineered for fixed mounting. Its threaded stud and mounting-hole pattern lock the connector firmly to the enclosure, preventing loosening under vibration - critical for touring racks and permanently installed distro systems alike.
