FAQs
AH420C12W uses back-wire termination for four conductors rated #12-10 AWG. For proper installation, strip conductors to the specified length (0.333-0.775 in), insert into the terminals, and tighten to the recommended 10 lbf-in torque. Ensure correct polarity and grounding in a three-pole, four-wire configuration for a secure, low-resistance connection.
Yes. The connector carries IP69K and IP67 ratings, making it suitable for high-pressure washdowns and damp environments common in food and beverage processing and wastewater treatment. Its nylon body and gasketed interfaces maintain a watertight seal even after repeated cleaning cycles, reducing ingress-related failures.
The device is rated for 20A at 125/250V, with three-pole, four-wire grounding and back-wire termination for #12-10 AWG conductors. Cord diameter compatibility ranges from 0.333 to 0.775 inches. Torque rating is 10 lbf-in, and the connector uses a nickel-plated brass contact set inside a nylon housings for durable, reliable mating.
AH420C12W carries cRUus recognition for North American safety. Its environmental ratings include IP67 and IP69K, aligning with stringent washdown and enclosure requirements in industrial settings. While it is compatible with Eaton Arrow Hart components, always verify specific project standards and local electrical codes during design.
The combination of a durable nylon body, nickel-plated brass contacts, and sealed IP ratings translates to extended service life and reduced replacement costs in harsh environments. Easy back-wire termination speeds installation, lowers labor time, and minimizes downtime, delivering a favorable total cost of ownership in automated systems and high-mix production environments.
