Frequently Asked Questions
Who should use KL-400SSMR and why?
Lighting technicians, electricians, and power distribution professionals working with 400 A temporary power systems will benefit from KL-400SSMR. Its red housing provides instant visual phase identification, while the Santoprene TPV (Thermoplastic Vulcanizate) housing rated to 105 °C ensures durability in demanding field conditions.
What voltage and amperage is KL-400SSMR rated for?
KL-400SSMR carries a maximum rating of 400 A and 600 V AC/DC. It accepts wire gauges from #6 to 4/0 AWG, making it suitable for the conductor sizes typically used in 400-amp power distribution circuits.
Why choose the red version of the K-LOK 400 A 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-400SSMR in red ensures your power distribution system follows established color conventions, speeding up setup and reducing wiring errors.
Is KL-400SSMR UL / UL / UL / cUL Listed and what does that mean?
Yes. KL-400SSMR is UL / UL / 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-400SSMR?
KL-400SSMR is widely used in broadcast operations and outside broadcast (OB) van power distribution. Its 400 A / 600 V 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 housing material is used in KL-400SSMR and why does it matter?
KL-400SSMR uses a Santoprene TPV (Thermoplastic Vulcanizate) housing rated to 105 °C. Santoprene TPV is chosen for its combination of rubber-like flexibility, heat resistance up to 105 °C, and resistance to oils, chemicals, and weathering - ideal for panel mount receptacles that remain permanently installed in demanding environments.
