Frequently Asked Questions
KL-400SSFR FAQ
What kind of connector is KL-400SSFR?
KL-400SSFR is a 400-ampere, 600V AC/DC single-pole female panel mount receptacle (Double Set Screw Type) from the KUPO K-LOK series. Finished in red, 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-400SSFR safely carry?
KL-400SSFR 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 red color coding on KL-400SSFR help on a busy job site?
On a crowded set or event site, identifying conductors quickly is a safety essential. Red marks Phase B (L2) in North American wiring and Phase C (L3) under Chinese GB 50303 standards. It is one of the most visually distinctive colors on a busy job site, helping crews quickly trace the second phase conductor. The red KL-400SSFR connector lets technicians trace circuits visually without needing to check labels or test equipment.
What safety certifications does KL-400SSFR hold?
KL-400SSFR is cRUus Listed (UL and cUL) 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-400SSFR work with connectors from other brands?
Absolutely. The K-LOK 400A series uses the industry-standard CAM-type interface, so KL-400SSFR mates directly with compatible single-pole connectors regardless of manufacturer. This makes it easy to expand or upgrade your connector stock incrementally.
