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 does KL-400SSMGY do and where is it typically used?
KL-400SSMGY provides a safe, reliable single-pole male connection point for 400A circuits at up to 600V AC / 250V DC. As a panel mount receptacle with gray color coding, it is commonly used in professional entertainment power distribution, temporary construction feeds, and industrial installations.
What are the electrical ratings of KL-400SSMGY?
KL-400SSMGY is rated for 400 amperes maximum continuous current at 600V AC / 250V DC maximum. It accepts conductors from #6 to 4/0 AWG (American Wire Gauge; UL evaluated with 4/0 AWG), with brass contacts delivering low-resistance connections for sustained high-current loads.
What does the gray housing on KL-400SSMGY signify?
Gray represents Phase C (L3) under the IEC color code. In North America, gray is also permitted for the neutral conductor. Adding gray to the connector inventory ensures full IEC three-phase coverage alongside brown and black. Color-coded connectors like KL-400SSMGY allow crews to visually verify correct phase wiring at a glance, which is especially valuable during fast-paced load-ins and load-outs.
What safety standards apply to KL-400SSMGY?
KL-400SSMGY meets UL 1691 (Single Pole Locking-Type Separable Connectors), is UL Listed under UL File E332947, rated UL Enclosure Type 3R (when mated) for weather resistance, carries a UL94 HB flame rating, and complies with RoHS hazardous substance restrictions. These certifications collectively ensure the connector is safe for professional use in entertainment and industrial environments.
Where is KL-400SSMGY commonly deployed?
You will find KL-400SSMGY in live event and touring power, film and broadcast production, trade shows, and industrial and emergency temporary power. The gray color coding and 400-amp capacity make it particularly well suited for multi-phase power distribution in professional settings.
What is the advantage of the double set screw design on KL-400SSMGY?
The double set screw termination on KL-400SSMGY 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.
