Frequently Asked Questions
KL-400LMY FAQ
What kind of connector is KL-400LMY?
KL-400LMY is a 400-ampere, 600V AC/DC single-pole male inline cable connector from the KUPO K-LOK series. Finished in yellow, 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-400LMY safely carry?
KL-400LMY 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 yellow color coding on KL-400LMY help on a busy job site?
On a crowded set or event site, identifying conductors quickly is a safety essential. 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. The yellow KL-400LMY connector lets technicians trace circuits visually without needing to check labels or test equipment.
What safety certifications does KL-400LMY hold?
KL-400LMY 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-400LMY work with connectors from other brands?
Absolutely. The K-LOK 400A series uses the industry-standard CAM-type interface, so KL-400LMY mates directly with compatible single-pole connectors regardless of manufacturer. This makes it easy to expand or upgrade your connector stock incrementally.
