Frequently Asked Questions
Who should use KL-400SSFB and why?
Lighting technicians, electricians, and power distribution professionals working with 400A temporary power systems will benefit from KL-400SSFB. Its blue 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-400SSFB rated for?
KL-400SSFB carries a maximum rating of 400A and 600V AC / 250V DC. It accepts wire gauges from #6 to 4/0 AWG (UL evaluated with 4/0 AWG), making it suitable for the conductor sizes typically used in 400-amp power distribution circuits.
Why choose the blue version of the K-LOK 400A female panel mount receptacle?
In North America, blue designates Phase C (L3), completing the three-phase color set. Under IEC 60445, blue is reserved for the Neutral conductor - making this color essential for international projects and cross-border equipment pools. Choosing KL-400SSFB in blue ensures your power distribution system follows established color conventions, speeding up setup and reducing wiring errors.
Is KL-400SSFB UL listed and what does that mean?
Yes. KL-400SSFB is UL Listed under UL File Number E332947, meaning UL has independently tested and certified it to UL 1691 for the United States. The listing covers the United States.
What industries commonly use KL-400SSFB?
KL-400SSFB is used across live events and touring, film and broadcast, rental and staging inventories, and industrial temporary power. Its 400A / 600V AC / 250V DC rating, combined with CAM-type universal compatibility and blue phase coding, makes it a versatile choice across the entertainment, construction, and industrial sectors.
How is KL-400SSFB installed in a power distribution enclosure?
KL-400SSFB 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.
