Eaton Specification Sheet - AH420C7W
AH420C7W pin and sleeve connector is built to endure demanding industrial environments. The IP69K/IP67 environmental resistance protects against washdown and incidental moisture exposure, reducing unplanned downtime and maintenance costs in food and beverage and wastewater facilities. The 20A, 480V, three-phase rating supports higher load motor drives and equipment, improving overall line efficiency and reducing panel wiring complexity in automation cells. Nickel-plated brass contacts offer corrosion resistance and reliable conductivity, extending service life in challenging environments and lowering replacement costs. A nylon body with back-wire termination simplifies installation, enabling faster commissioning and safer terminations, while the compact form factor optimizes panel density for modern control enclosures. Compatibility with standard Eaton pin and sleeve devices ensures scalable, cost-effective expansion of power-distribution networks across facilities.

FAQs
AH420C7W uses a back-wire termination design that accepts #12-10 AWG conductors, enabling fast, secure field terminations. The four-wire configuration includes a dedicated grounding path and a three-pole arrangement for robust three-phase power. Torque specifications and contact geometry are optimized to maintain low-resistance connections while reducing installer effort and potential wiring errors.
The connector is rated for 20A at 480V in a three-phase, four-wire setup. It features nickel-plated brass contacts and a nylon housing designed for reliability in demanding environments. Cord diameter compatibility is 0.333-0.775 inches, supporting a range of field Equipment wiring while maintaining secure mating and high current handling.
Yes. AH420C7W carries IP69K and IP67 environmental protection, making it well-suited for washdown-heavy industries like food & beverage and wastewater treatment. Its nylon housing and corrosion-resistant contacts help withstand cleaning agents and moisture exposure, while maintaining electrical integrity and safe operation in demanding production environments.
The AH420C7W is certified cRUus, indicating compliance with North American safety standards. IP69K and IP67 ratings confirm watertight performance in high-pressure washdown scenarios. These certifications support regulatory compliance, reduce the need for site-specific testing, and enable faster project approvals in industrial facilities.
The combination of IP-rated sealing, durable nickel-plated contacts, and a robust nylon body lowers maintenance frequency by minimizing moisture ingress and contact wear. Back-wire terminations speed up serviceability, reducing downtime during inspections or after equipment upgrades. Over time, these factors contribute to lower total cost of ownership and improved uptime for motor drives and three-phase power systems.
