Product Description
The KUPO K-LOK 400A Male Panel Mount Inlet (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 kind of connector is KL-400SSMBK?
KL-400SSMBK is a 400-ampere, 600V AC / 250V DC single-pole male panel mount inlet (Double Set Screw Type) from the KUPO K-LOK series. Finished in black, it belongs to the CAM-type connector family widely used across live events, film production, and temporary industrial power systems.
How much current can KL-400SSMBK safely carry?
KL-400SSMBK is designed for a maximum continuous load of 400 amperes at up to 600V AC / 250V DC. The brass contacts and Santoprene TPV (Thermoplastic Vulcanizate) housing rated to 105 degrees Celsius work together to maintain safe operating temperatures even under sustained full-load conditions.
How does the black color coding on KL-400SSMBK help on a busy job site?
On a crowded set or event site, identifying conductors quickly is a safety essential. 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). The black KL-400SSMBK connector lets technicians trace circuits visually without needing to check labels or test equipment.
What safety certifications does KL-400SSMBK hold?
KL-400SSMBK is UL Listed under UL File Number E332947, certified to UL 1691, the standard for single-pole locking-type separable connectors, and rain tested to UL 50E. It carries a UL Enclosure Type 3R (when mated) environment rating, UL94 HB flame classification, and full RoHS (Restriction of Hazardous Substances) compliance.
Can KL-400SSMBK work with connectors from other brands?
Absolutely. The K-LOK 400A series uses the industry-standard CAM-type interface, so KL-400SSMBK mates directly with compatible single-pole connectors regardless of manufacturer. This makes it easy to expand or upgrade your connector stock incrementally.
What is the advantage of the double set screw design on KL-400SSMBK?
The double set screw termination on KL-400SSMBK 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.
