Eaton L820RWBK Watertight locking receptacle - cULus Listed
Part Number: L820RWBK
Quick Summary
The Eaton L820RWBK watertight locking receptacle provides reliable 480V two-pole power for industrial equipment. Moisture intrusion and harsh environments often complicate wiring, lead to corrosion, and slow installations; this receptacle is designed to combat those challenges. It carries cULus listing and RoHS compliance, while delivering IP66/NEMA 3R and NEMA 4X protection for washdown and rugged sites. By combining a durable thermoplastic body with a nickel plated bronze contact system, it supports long service life and low maintenance. In addition to core safety, the unit offers back-wiring compatibility and clear field-installation benefits, aligning with procurement goals and reducing total cost of ownership while staying compatible with Arrow Hart locking devices.

Feature → Business Impact → Application: The L820RWBK is rated for 20A at 480V in a two-pole, three-wire configuration (L8-20) with back wiring. This enables standard industrial power connections and simplifies installation, reducing project lead times on conveyors, pumps, and control panels. Application: industrial machinery and outdoor equipment where reliable 480V power is needed. Feature → Business Impact → Application: Watertight performance with NEMA 3R, IP66, NEMA 4X, NEMA 12, and NEMA 4 ratings protects against moisture, dust, and washdowns. This translates to lower maintenance costs and safer operation in washdown zones and outdoor installations. Application: food processing, water treatment, outdoor machinery. Feature → Business Impact → Application: Glass-filled nylon face/body and thermoplastic housing deliver exceptional impact resistance and chemical durability. This reduces replacement frequency and failure risk in harsh industrial environments. Application: rugged OEM enclosures and manufacturing floors. Feature → Business Impact → Application: Nickel-plated bronze contacts paired with a robust locking contact mechanism ensures secure mating and repeatable torque performance. This improves electrical reliability and reduces rework in high-vibration settings. Application: metal fabrication and heavy equipment. Feature → Business Impact → Application: Back wiring, RoHS compliance, and cULus listing simplify compliance, documentation, and on-site inspections. This supports faster commissioning and smoother maintenance cycles. Application: plant-wide installations and regulated environments.

FAQs
The L820RWBK uses the standard L8-20 two-pole, three-wire locking configuration and back-wiring method, ensuring straightforward integration with typical Eaton Arrow Hart interfaces and many third-party enclosures. Its thermoplastic, glass-filled nylon body resists impact, while the nickel-plated bronze contacts provide reliable mating performance in vibration-prone installations.
This receptacle is rated for 20A at 480V with L8-20 configuration, two poles, and three wires including a grounding conductor. These ratings support heavy-duty industrial motors, pumps, and conveyors while ensuring proper current capacity and safety margins for typical 480V power distribution systems.
Yes. With IP66 and NEMA 3R/NEMA 4X protection ratings, the receptacle is designed to withstand washdowns, dust, and moisture. This makes it appropriate for outdoor equipment, food processing, and other environments where exposure to water or cleaning agents is routine.
The L820RWBK is RoHS Compliant and cULus Listed, providing assurance for regulatory and safety standards in North America. Its environmental ratings (IP66/NEMA 3R/NEMA 4X) further support compliance in environments requiring moisture and particulate protection.
The locking design reduces accidental disconnections, improving uptime in high-vibration settings. Thermoplastic construction and corrosion-resistant contacts lower replacement costs, while back wiring speeds up installation and future servicing, delivering a lower total cost of ownership over the device lifecycle.
