Quick Summary

Eaton 7411PWBK watertight locking plug provides secure, moisture-resistant connections for industrial panels and equipment. This harness-ready plug handles #18-10 AWG conductors at 20A in 120/208 V three-phase systems, delivering reliable power where downtime is costly. The back-wiring design simplifies field assembly, reducing installation time and error. In challenging environments, the unit’s NEMA 6P, NEMA 4, NEMA 4X, and IP67 ratings guard against water, dust, and washdowns. With a nylon body, nickel-plated brass contacts, and Santoprene elastomeric seals, it withstands harsh conditions while maintaining electrical integrity. For reliability-driven projects, its extra-heavy-duty industrial specification grade aligns with rigorous safety and compliance requirements, complementing Eaton Arrow Hart power distribution solutions and existing panel architectures.

Locking plug
Watertight, locking plug design provides a secure connection that resists moisture ingress and accidental disconnection. This reduces corrosion risks and unplanned downtime in washdown zones and outdoor enclosures. It supports durable automation panels across manufacturing, water treatment, and food processing environments. Torque rating of 14-16 lbf-in ensures a proper seat and long-term integrity, translating to consistent electrical contact pressure, reduced hot spots, and minimized maintenance checks on critical lines. In panel builds, back-wiring with #18-10 AWG wires speeds assembly without sacrificing reliability. Nickel-plated brass contacts and Santoprene seals deliver corrosion resistance and effective sealing, resulting in extended service life in harsh environments with moisture, oils, or washdowns. This combination supports compliance with IP67 and multiple NEMA ratings while maintaining low contact resistance. The nylon body with a robust device grade (extra heavy-duty industrial specification) provides rugged mechanical support, improving vibration resistance in automation lines and reducing failure rates in heavy-use installations. Back wiring and the back-wiring method facilitate fast field installation and easier future maintenance, helping technicians meet tight project timelines and reduce wiring errors in dense control panels. The four-pole, four-wire configuration (non-grounding) supports clean, standardized power distribution and simplifies diagnostics in complex automation architectures.

FAQs

Installation with back-wiring is straightforward: terminate #18-10 AWG conductors in the four-wire plug and tighten to 14-16 lbf-in. This back-wiring design simplifies field assembly and reduces wiring errors in dense control panels. Pair with standard Eaton Arrow Hart components to ensure correct polarity and a secure, code-compliant connection in industrial environments.
The 7411PWBK is rated for 20A at 120/208V in a four-pole, four-wire, non-grounding configuration. It uses nickel-plated brass contacts with a nylon body and Santoprene seals, designed for three-phase power. It supports IP67 and NEMA 6/4/4X environments, making it suitable for rugged industrial installations.
Yes. It is designed for washdown and outdoor environments thanks to IP67 and multiple NEMA protections (4, 4X, 6, 6P). The Santoprene seals and nylon body resist moisture and dust, maintaining electrical integrity in harsh settings. For outdoor use, ensure mating components carry compatible ratings to preserve system integrity.
The plug is cULus Listed NOM, providing safety compliance for North American installations. When paired with IP67/NEMA 4/4X/6 protections, these certifications help meet regulatory requirements for industrial equipment, support safer audits, and reduce the risk of nonconformity in controlled environments.
The watertight locking design minimizes moisture-related faults and loosening connections in vibration-heavy lines, reducing downtime. Back-wiring lowers installation labor, while durable nickel-plated brass contacts and Santoprene seals extend service intervals. Overall, this translates to improved equipment reliability, lower maintenance costs, and higher OEE in manufacturing and processing facilities.
