Eaton Specification Sheet - CS8464EX
Feature → Business Impact → Application: Locking mechanism and Pro Grip design provide vibration resistance and secure terminations, reducing field rework and warranty claims in noisy industrial environments. The result is increased uptime on packaging lines and stamping presses where panels experience constant motion or shocks. Feature → Business Impact → Application: 50 A at 480 V ratings support high-power devices without overfusing, enabling simpler wire management in motor starters and feeder circuits. This translates to fewer components, faster installations, and improved energy efficiency in automated lines. Feature → Business Impact → Application: Back wiring compatibility with #10-4 AWG conductors streamlines field terminations, lowering installation time and training needs for electricians and apprentices in machine builds and retrofit projects. Feature → Business Impact → Application: Glass-filled nylon body and zinc-plated brass contacts deliver durable, corrosion-resistant performance in humid or dusty environments, extending product life and reducing maintenance costs in outdoor enclosures and process plants. Feature → Business Impact → Application: -40 to 105 °C operating range supports aerospace, food & beverage, and chemical environments where ambient temps swing, ensuring reliable operation and regulatory compliance. Feature → Business Impact → Application: cULus Listed and California standard compliance reduce risk during audits and line-change approvals, helping OEMs meet local electrical codes while maintaining supply chain resilience. The combination of compact dimensions (6.94 in length, 3.38 in height, 3.61 in width) and integrated locking reduces panel footprint and simplifies panel design for single- or multi-connector configurations.

FAQs
CS8464EX uses back wiring with a 50 A amperage rating, making it suitable for high-load industrial applications where secure terminations are essential. The back-wiring design simplifies field terminations and reduces the risk of loose connections in equipment panels, feeders, and motor control centers.
Yes, CS8464EX is designed to meet California standard requirements and is compatible with systems that require California standard locking connectivity. It supports cord diameters from 0.44 to 1.06 inches (11.1–26.0 mm), enabling use with a wide range of #10–4 AWG conductors depending on configuration.
CS8464EX carries cULus Listed certification and adheres to California standard practices. It operates from -40 to 105 °C and uses a glass-filled nylon body with zinc-plated brass contacts, providing durability in harsh environments typical of industrial facilities and manufacturing floors.
The Pro Grip locking design ensures a secure, vibration-resistant connection that resists inadvertent disconnections in equipment subject to shocks, vibrations, and frequent door openings. This reduces downtime, minimizes maintenance, and improves overall system reliability in control panels and heavy machinery.
Ensure the correct wire size within the allowable range (#10–4 AWG) and proper torque (45 lbf-in) to achieve a reliable seal and engagement. Use the locking connector in back-wired configurations for non-NEMA, two-pole, three-wire applications, and verify cULus and California standard compliance during audits to minimize regulatory exposure.
