Product Description
The KUPO K-LOK 400A Female Panel Mount Receptacle (Double Set Screw Type) is engineered for secure, permanent installation in high-current power distribution enclosures and panel assemblies where double set screw termination is preferred. Featuring a Santoprene TPV (Thermoplastic Vulcanizate) housing rated to 105 degrees Celsius, brass contacts for superior conductivity, and a double set screw connection for robust cable retention, this connector delivers the structural integrity and electrical performance required by large-scale entertainment productions and industrial power systems handling up to 400 amperes. Full interoperability with standard CAM-type connectors ensures seamless integration into existing power distribution infrastructure.

Frequently Asked Questions
What is KL-400SSFBK and what is it designed for?
KL-400SSFBK is a KUPO K-LOK 400A single-pole female panel mount receptacle (Double Set Screw Type) with a black housing, rated for 600V AC / 250V DC maximum. It is engineered for heavy-duty temporary power distribution in entertainment, industrial, and event production settings. The black color coding aids rapid phase identification on the job site.
What wire sizes does KL-400SSFBK accept?
KL-400SSFBK accommodates conductors ranging from #6 to 4/0 AWG (UL evaluated with 4/0 AWG). The brass contact assembly ensures reliable electrical performance across this full conductor range, supporting up to 400A at 600V AC / 250V DC.
Which electrical phase does the black color represent on KL-400SSFBK?
Under North American NEMA/NEC conventions, black identifies Phase A (L1), making it the go-to choice for single-phase circuits and the default lead in three-phase systems. In IEC regions, black denotes Phase B (L2). Having a dedicated black connector in your inventory means phase assignments are physically enforced, minimizing the chance of cross-phase connection errors.
How does KL-400SSFBK protect against electrical hazards?
KL-400SSFBK 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, UL Listed under UL File E332947. The Type 3R rating (when mated) means the connector is suitable for outdoor use, with a degree of protection against rain, sleet and external ice formation.
Is KL-400SSFBK compatible with other CAM-type connectors?
Yes. KL-400SSFBK 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.
What is the advantage of the double set screw design on KL-400SSFBK?
The double set screw termination on KL-400SSFBK provides redundant cable clamping - each screw independently secures the conductor, adding a layer of safety against vibration-induced loosening. This is particularly valuable in touring rigs and mobile power systems where connectors experience constant mechanical stress.
