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 kind of connector is KL-400SSFBN?
KL-400SSFBN is a 400-ampere, 600V AC / 250V DC single-pole female panel mount receptacle (Double Set Screw Type) from the KUPO K-LOK series. Finished in brown, 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-400SSFBN safely carry?
KL-400SSFBN 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 brown color coding on KL-400SSFBN help on a busy job site?
On a crowded set or event site, identifying conductors quickly is a safety essential. Brown designates Phase A (L1) under the IEC 60445 color code used across Europe, the UK and much of Asia. For productions touring internationally or venues hosting global acts, brown connectors ensure IEC-standard phase identification is always available. The brown KL-400SSFBN connector lets technicians trace circuits visually without needing to check labels or test equipment.
What safety certifications does KL-400SSFBN hold?
KL-400SSFBN 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-400SSFBN work with connectors from other brands?
Absolutely. The K-LOK 400A series uses the industry-standard CAM-type interface, so KL-400SSFBN mates directly with compatible single-pole connectors regardless of manufacturer. This makes it easy to expand or upgrade your connector stock incrementally.
How is KL-400SSFBN installed in a power distribution enclosure?
KL-400SSFBN 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.
