Frequently Asked Questions
Who should use KL-150SMR and why?
Lighting technicians, electricians, and power distribution professionals working with 150A temporary power systems will benefit from KL-150SMR. Its red housing provides instant visual phase identification, while the Santoprene TPV (Thermoplastic Vulcanizate) housing rated to 105 degrees Celsius ensures durability in demanding field conditions.
What voltage and amperage is KL-150SMR rated for?
KL-150SMR carries a maximum rating of 150A and 600V AC/DC. It accepts wire gauges from #8 to #2 AWG, making it suitable for the conductor sizes typically used in 150-amp power distribution circuits.
Why choose the red version of the K-LOK 150A male panel mount receptacle?
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. Choosing KL-150SMR in red ensures your power distribution system follows established color conventions, speeding up setup and reducing wiring errors.
Is KL-150SMR UL listed and what does that mean?
Yes. KL-150SMR is cUL Listed under File Number E332947, meaning it has been independently tested and certified to UL 1691 safety standards by a Nationally Recognized Testing Laboratory. This certification is required for professional power distribution in most North American jurisdictions.
What industries commonly use KL-150SMR?
KL-150SMR is widely used in rental house and staging company inventories serving diverse entertainment clients. Its 150A / 600V AC/DC rating, combined with CAM-type universal compatibility and red phase coding, makes it a versatile choice across the entertainment, construction, and industrial sectors.
What makes KL-150SMR suitable for permanent installations?
Unlike inline connectors designed for repeated connection and disconnection, KL-150SMR 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.
