Product Description
Overview
The KUPO K-LOK 400 A Female Panel Mount Receptacle (Thread-Stud Type) is engineered for secure, permanent installation in high-current power distribution enclosures, distro boxes, and panel assemblies. Featuring a Santoprene TPV (Thermoplastic Vulcanizate) housing rated to 105 °C, brass contacts for superior conductivity, and a threaded-stud conductor termination and separate mounting holes for enclosure attachment, 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.
Key Features
- Dedicated mounting holes secure the connector to the panel; the threaded stud is the conductor termination
- Santoprene TPV housing rated to 105 °C withstands demanding conditions in permanent installations
- Brass contacts deliver reliable, low-resistance electrical connections for sustained high-current loads up to 400 A
- Threaded stud connection provides strong, vibration-resistant termination for panel-through wiring accommodating #6 AWG to 4/0 AWG conductors
- Universal CAM-type compatibility integrates seamlessly with existing inline connectors from multiple manufacturers
- UL / cUL Listed ensures compliance with North American safety standards
Standards
UL / cUL Listed -File Number E332947; UL 1691 - Standard for Safety for Cam-Type, Locking-Type Separable Connectors; Environment Rating: UL Enclosure Types 3R; Flame Class: HB / UL94; RoHS (Restriction of Hazardous Substances) Compliant. Match standards and compliance requirements to the local electrical code before installation.
Applications
Suitable for concert touring and live event production, film, television, and studio power distribution, temporary construction site power, theme park and entertainment venue installations, trade shows and exhibition power systems, industrial temporary power connections, and broadcast and outside broadcast (OB) van power.
Compatibility
The K-LOK 400 A Female Panel Mount Receptacle intermates with standard CAM-type single-pole connectors from all major manufacturers, enabling seamless integration into existing power distribution systems without requiring a full infrastructure change.

Frequently Asked Questions
What is KL-400SFGY and what is it designed for?
KL-400SFGY is a KUPO K-LOK 400 A single-pole female panel mount receptacle (Thread-Stud Type) with a grey 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 grey color coding aids rapid phase identification on the job site.
What wire sizes does KL-400SFGY accept?
KL-400SFGY accommodates conductors ranging from #6 to 4/0 AWG. Maximum connector rating: 400 A, 600 V AC/DC.
Which electrical phase does the grey color represent on KL-400SFGY?
Grey identifies L3 in the IEC UK/EU color scheme and neutral in the North American 277/480 V color scheme. Follow the color scheme specified for the installation. Adding grey to the connector inventory ensures full IEC three-phase coverage alongside brown and black. Having a dedicated grey connector in your inventory means the housing provides a visual identification aid.
How does KL-400SFGY protect against electrical hazards?
KL-400SFGY 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 / cUL Listed E332947. The UL Enclosure Types 3R rating also provides protection in wet or outdoor conditions.
Is KL-400SFGY compatible with other CAM-type connectors?
Yes. KL-400SFGY 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 makes KL-400SFGY suitable for permanent installations?
Unlike inline connectors designed for repeated connection and disconnection, KL-400SFGY is engineered for fixed mounting. The mounting holes secure the connector to the enclosure. The threaded stud is the conductor termination, not the panel fixing.
