Eaton L820CW Watertight Locking Connector - IP67
Part Number: L820CW
Quick Summary
The Eaton L820CW watertight locking connector is designed for robust industrial power connections in harsh environments. It delivers reliable, moisture- and dust-resistant performance essential for wet plant floors, outdoor equipment, and heavy machinery. Engineers often wrestle with moisture intrusion, electrical arcing, and connectors that loosen under vibration, leading to downtime. The L820CW carries IP67 protection and NEMA 6P/4X compatibility, along with RoHS compliance and cULus listing, ensuring safety and regulatory alignment across global projects. This solution also supports back wiring with #18-10 AWG conductors, enabling faster terminations and cleaner panels. For procurement and maintenance teams, the combination of rugged durability, standardized wiring, and a compact footprint translates to lower installation costs and longer service intervals in demanding environments.

FAQs
Yes. The L820CW is designed for L8-20 two-pole, three-wire circuits and supports back wiring with #18-10 AWG conductors. It uses a nylon body with nickel-plated brass contacts and a torque range of 14-16 lbf-in to ensure a secure, vibration-resistant connection in industrial panels.
The connector is rated for 20A at 480V, features IP67 protection, and corresponds to NEMA L8-20 configurations. It supports two poles with three wires (one grounding) and relies on a locking mechanism to resist vibration, with a torque rating of 14-16 lbf-in to maintain a reliable connection.
Best suited for wet, dusty, or outdoor industrial environments, including washdown areas and rugged manufacturing floors. IP67 and NEMA 6P/4X compatibility ensure protection against water, dust, and corrosion. The locking design minimizes accidental disconnections during operation, even in harsh conditions.
The L820CW is RoHS compliant and cULus-listed, aligning with global safety and environmental standards. These certifications support regulatory compliance for widespread industrial deployments and help simplify supplier qualification and audits in regulated industries.
By combining watertight performance, reliable back wiring, and a robust locking mechanism, the L820CW reduces maintenance frequency and downtime caused by ingress, loosening connections, or wiring faults. Its durable materials and standardized dimensions enable faster installs, fewer part replacements, and predictable long-term operating costs for industrial facilities.
