Frequently Asked Questions
What is KL-150LMR and what is it designed for?
KL-150LMR is a KUPO K-LOK 150A single-pole male inline cable connector with a red housing, rated for 600V AC/DC maximum. It is engineered for heavy-duty temporary power distribution in entertainment, industrial, and event production settings. The red color coding aids rapid phase identification on the job site.
What wire sizes does KL-150LMR accept?
KL-150LMR accommodates conductors ranging from #8 to #2 AWG. The brass contact assembly ensures reliable electrical performance across this full conductor range, supporting up to 150A at 600V AC/DC.
Which electrical phase does the red color represent on KL-150LMR?
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. Having a dedicated red connector in your inventory means phase assignments are physically enforced, minimizing the chance of cross-phase connection errors.
How does KL-150LMR protect against electrical hazards?
KL-150LMR incorporates multiple safety features: the non-conductive POM retaining screw prevents accidental current paths through the housing, the Santoprene TPV (Thermoplastic Vulcanizate) housing rated to 105 degrees Celsius resists heat and impact, brass contacts minimize resistive heating, and the design meets UL 1691 safety requirements under cUL Listed E332947. The UL Enclosure Types 3R rating also provides protection in wet or outdoor conditions.
Is KL-150LMR compatible with other CAM-type connectors?
Yes. KL-150LMR follows the universal CAM-type single-pole connector standard and intermates with CAM-type connectors from all major manufacturers. This cross-brand compatibility means you can integrate K-LOK connectors into existing power distribution systems without replacing your entire inventory.
What housing material is used in KL-150LMR and why does it matter?
KL-150LMR uses a Santoprene TPV (Thermoplastic Vulcanizate) housing rated to 105 degrees Celsius. Santoprene TPV combines the flexibility of rubber with the processing advantages of thermoplastic, delivering excellent chemical resistance, UV stability, and durability under repeated mechanical stress - exactly what professional power connectors face on tour and on set.
