Eaton 15W33 Watertight Straight Blade Connector - IP67
Part Number: 15W33
Quick Summary
Eaton 15W33 watertight straight blade connector delivers sealed power connections for industrial equipment in harsh environments. In damp or outdoor installations, moisture ingress and loose terminations disrupt uptime and increase maintenance costs. This product is cULus Listed, IP67-rated, suitable for damp/wet conditions, and supports two-pole grounding with back-wire screw terminations. For engineers and buyers, the 15W33 offers reliable compatibility with #18-10 AWG and bulk packaging, reducing field rework and warranty exposure, while improving installation efficiency in industrial control panels. With its nickel-plated brass contacts and Santoprene body, it resists corrosion and helps keep control systems energized during washdowns and rain. Across installations, its back-wire and screw-connection approach minimizes tool requirements and speeds panel assembly.

FAQs
Begin by selecting #18-10 AWG conductors and ensuring the device is de-energized. Open the back-wire terminals, insert conductors following the rated polarity, and tighten the screws to the specified torque (14 lbf-in). Verify the grounding path, close the housing, and perform a resistance and insulation check per your site standards. The back-wire design simplifies wiring, while the screw terminals provide a redundant termination method if needed.
The 15W33 is rated for 20A at 125V and accepts #18-10 AWG conductors. It is a two-pole, three-wire, grounding receptacle configured as NEMA 5-20R, designed for industrial use with back-wire and screw termination options. This combination supports reliable power delivery in demanding environments while maintaining code compliance.
Yes. The 15W33 carries IP67 environmental resistance and a damp/wet environmental condition rating, making it appropriate for outdoor installations and wash-down areas. Its Santoprene housing and nickel-plated brass contacts provide corrosion resistance, helping maintain long-term performance even in challenging industrial settings.
The connector is cULus Listed, confirming adherence to recognized safety standards in North America. It also features IP67 sealing, ensuring ingress protection against dust and water. These certifications support compliance in regulated industrial environments and assist in meeting installation and maintenance requirements for rugged equipment.
The combination of IP67 sealing, corrosion-resistant nickel-plated brass contacts, and Santoprene housing reduces moisture-related faults and maintenance needs. Quick back-wire terminations speed field wiring, lowering labor costs and downtime. Over its lifecycle, this translates to lower replacement frequency, improved uptime, and a favorable return on investment for OEMs and maintenance teams.
