Product Description
Overview
The KUPO K-LOK 400 A Male 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 does KL-400SSMGY do and where is it typically used?
KL-400SSMGY provides a safe, reliable single-pole male connection point for 400 A circuits at up to 600 V AC/DC. As a panel mount receptacle with grey color coding, it is commonly used in 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 600 V AC/DC maximum. It accepts conductors from #6 to 4/0 AWG (American Wire Gauge), with brass contacts delivering low-resistance connections for sustained high-current loads.
What does the grey housing on KL-400SSMGY signify?
Grey represents Phase C (L3) - and in some IEC applications, Neutral - under the international color code. Adding grey 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 ( Cam-Type, Locking-Type Separable Connectors), is UL / UL / cUL Listed under E332947, rated UL Enclosure Types 3R for weather resistance, carries a HB / UL94 flame class, 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 at work in studio power distribution in recording, post-production, and live broadcast environments. The grey 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.
