Frequently Asked Questions
KL-400SMBN FAQ
What is KL-400SMBN and what is it designed for?
KL-400SMBN is a KUPO K-LOK 400A single-pole male panel mount receptacle (Thread-Stud Type) with a brown housing, rated for 600V AC/DC maximum. It is engineered for heavy-duty temporary power distribution in entertainment, industrial, and event production settings. The brown color coding aids rapid phase identification on the job site.
What wire sizes does KL-400SMBN accept?
KL-400SMBN accommodates conductors ranging from #6 to 4/0 AWG. The brass contact assembly ensures reliable electrical performance across this full conductor range, supporting up to 400A at 600V AC/DC.
Which electrical phase does the brown color represent on KL-400SMBN?
Brown designates Phase A (L1) under IEC 60446 conventions used across Europe, the UK, Asia, and Australia. For productions touring internationally or venues hosting global acts, brown connectors ensure IEC-standard phase identification is always available. Having a dedicated brown connector in your inventory means phase assignments are physically enforced, minimizing the chance of cross-phase connection errors.
How does KL-400SMBN protect against electrical hazards?
KL-400SMBN incorporates multiple safety features: 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 cRUus listing E332947. The UL Enclosure Types 3R rating also provides protection in wet or outdoor conditions.
Is KL-400SMBN compatible with other CAM-type connectors?
Yes. KL-400SMBN 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.
