FAQs
The 3431PW supports back wiring with allowable conductors sized #18 to #10 AWG. This enables clean terminations in compact panels while preserving conductor integrity. The design pairs with nickel-plated brass contacts to maintain a reliable connection under vibration and rough handling commonly seen in industrial environments.
This plug is rated for 30A at 120/208V (3ØY) and features four poles with a non-grounding configuration. It offers IP67 environmental protection and is listed under cULus, with additional NEMA protections including 4, 4X, 6, and 6P, ensuring dependable performance in harsh, washdown, and outdoor settings.
Yes. The combination of IP67 sealing, NEMA 4/6/4X/6P protection, and a durable yellow nylon body makes the 3431PW well-suited for outdoor, wet, dusty, and vibration-prone applications. It provides reliable locking engagement to prevent accidental disconnection in demanding production environments.
The 3431PW is cULus Listed, which supports compliance with North American electrical safety standards. IP67 and the associated NEMA ratings further verify protection against ingress and environmental hazards. These certifications help satisfy regulatory requirements and support safer procurement decisions for industrial systems.
Back wiring reduces termination time and simplifies field assembly, cutting labor costs and downtime. The locking connector design provides a secure, vibration-resistant connection, minimizing maintenance interventions. Durable materials like nylon and nickel-plated brass extend service life, improving total cost of ownership in automated facilities.
