Locking plug
Watertight locking plug with a nylon body and Santoprene elastomeric seal provides a moisture-resistant interface, reducing corrosion and downtime. This design translates to less frequent maintenance and longer service life in wet or dusty environments, especially in outdoor installations and washdown areas. The 30A, 120/208V, four-pole, non-grounding configuration supports standard industrial three-phase power distribution while enabling clean, organized panel layouts and safer wiring practices. Back-wiring for #14-10 AWG conductors speeds field terminations and minimizes wiring errors, directly cutting installation time and labor costs. Nickel-plated brass contacts deliver reliable conductivity and wear resistance, enhancing performance during high-cycle operations and frequent mating/demating cycles. Environmental protection ratings NEMA 4X, 4, 6, 6P and IP67 ensure rugged sealing, reducing inadvertent ingress in challenging environments. The 20 lbf-inch torque rating stabilizes connections without over-tightening, improving consistency across assemblies in production lines and field repairs. This combination supports easier compliance with installation standards and reduces rework caused by loose or moisture-affected connections.

FAQs
The back-wiring method accepts #14-10 AWG conductors, simplifying field terminations. Ensure the mating receptacle is aligned, strip insulation to the recommended depth, insert conductors into the correct terminals, and torque to 20 lbf-in as specified. Use the nickel-plated brass contacts for reliable conductivity and secure the strain-relief to prevent conductor movement, then verify continuity and insulation resistance before commissioning.
This model is designed for 3ØY 120/208V, featuring a four-pole, non-grounding, four-wire configuration rated at 30A. It supports back-wiring for #14-10 AWG conductors, enabling clean, safe terminations in control panels and machine enclosures. Its design maintains voltage integrity and reduces impedance in typical industrial three-phase applications, improving start-up reliability and overall system performance.
Yes. The connector is cULus Listed and built for harsh environments, delivering IP67 protection and NEMA 4X/4/6/6P ratings. These certifications and ratings translate to dependable moisture sealing, dust exclusion, and water ingress resistance, making it suitable for outdoor, washdown, and high-humidity installations in accordance with industry guidelines.
Key advantages include a watertight seal, back-wiring compatibility with #14-10 AWG conductors, and a torque rating of 20 lbf-in that prevents over-tightening. The nylon body with a Santoprene elastomeric seal provides robust sealing, while nickel-plated contacts reduce wear and maintain low contact resistance. These features collectively speed up installation, reduce maintenance, and enhance reliability in outdoor or washdown settings.
Installing the 3433CWBK can lower total cost of ownership by reducing maintenance cycles due to improved sealing and contact durability. Its back-wiring capability speeds field terminations, cutting labor hours during panel assembly. The combination of robust environmental ratings and reliable electrical performance minimizes downtime, supports longer service intervals, and improves overall equipment availability in demanding industrial environments.
