Frequently Asked Questions
Who should use KL-400SSMBN and why?
Lighting technicians, electricians, and power distribution professionals working with 400 A temporary power systems will benefit from KL-400SSMBN. Its brown 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-400SSMBN rated for?
KL-400SSMBN 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 brown version of the K-LOK 400 A male panel mount receptacle?
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. Choosing KL-400SSMBN in brown ensures your power distribution system follows established color conventions, speeding up setup and reducing wiring errors.
Is KL-400SSMBN UL / UL / UL / cUL Listed and what does that mean?
Yes. KL-400SSMBN 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-400SSMBN?
KL-400SSMBN is widely used in industrial temporary power connections for manufacturing and processing facilities. Its 400 A / 600 V AC/DC rating, combined with CAM-type universal compatibility and brown phase coding, makes it a versatile choice across the entertainment, construction, and industrial sectors.
How is KL-400SSMBN installed in a power distribution enclosure?
KL-400SSMBN uses a double set screw panel-mount design with dedicated mounting holes for secure attachment to enclosures and distro boxes. The double set screw termination provides redundant cable retention - two independent screws clamp the conductor, so even if one loosens under vibration, the connection remains intact.
