Eaton CS8364EX Locking Connector - California Standard
Part Number: CS8364EX
Quick Summary
The Eaton CS8364EX locking connector provides a reliable industrial power link for control panels. Users often grapple with accidental unplugging in harsh environments, which disrupts uptime and safety. It is cULus Listed, rated for -40 to 105 C, and built to California standard specs with a glass-filled nylon body for durability. With a 50 A, 250 V, three-pole, four-wire configuration and back-wiring capability, it supports #10-4 AWG conductors and a 0.44–1.06 in cord diameter. The locking Pro Grip design reduces vibration-induced disengagement in machinery, and the rugged zinc-plated brass contacts ensure long life in industrial settings. These features translate into improved reliability, safer maintenance windows, and lower total cost of ownership.

FAQs
CS8364EX supports back wiring for quick terminations and accepts #10-4 AWG conductors, enabling fast, secure connections in control panels and industrial enclosures. This method reduces field termination time and improves reliability in vibrating equipment.
CS8364EX is rated for 50 A and 250 V three-pole operation with four wires, making it suitable for industrial motors, feeders, and robust control circuits while maintaining safety margins in demanding environments.
Yes. The CS8364EX provides a 3Ø 250 V configuration with a non-NEMA footprint, designed for California standard installations and industrial equipment that requires a secure locking interlock rather than a conventional NEMA plug.
CS8364EX is cULus Listed and built to California standard specs, offering regulatory confidence for installations in regulated facilities and improving supplier qualification during procurement.
Plan for back-wiring termination with #10-4 AWG conductors, ensure torque is applied to 45 in-lbf for secure connections, and verify the -40 to 105 C operating range to prevent insulation or contact degradation in extreme environments.
