Product Description
Overview
The KUPO K-LOK 400 A 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 °C, 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 400 A single-pole female panel mount receptacle (Double Set Screw Type) with a black housing, rated for 600 V AC/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. The brass contact assembly ensures reliable electrical performance across this full conductor range, supporting up to 400 A at 600 V AC/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 °C resists heat and impact, brass contacts minimize resistive heating, and the design meets UL 1691 safety requirements under UL / UL / cUL Listed E332947. The UL Enclosure Types 3R rating also provides protection in wet or outdoor conditions.
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.
