FAQs
To install AH5666Y, remove the panel cover, strip conductors to the recommended length, insert each conductor into the back-wire terminal under the clamp, and tighten the screw to the specified torque range of 12-14 lbf-in. Verify conductor seating and perform a continuity check. This method reduces field termination time and ensures a secure, vibration-resistant connection.
AH5666Y uses a 6-15P NEMA configuration rated for 15A at 250V, with two-pole, three-wire grounding. This matches common industrial power circuits, simplifies wiring schemes, and minimizes the need for adapters. Its back-wire option and rigid nylon housing support reliable panel wiring in manufacturing environments.
Yes. AH5666Y is RoHS compliant and carries UL/NOM and Federal Specification 6221-02 listings, confirming safety, material restrictions, and regulatory compliance. These certifications simplify cross-border procurement and support audits for OEMs and integrators deploying equipment across multiple regions.
Absolutely. AH5666Y is designed for #16-12 AWG conductors with back-wire termination and a screw connection. This enables secure, repeatable terminations, reduces the chance of conductor damage during installation, and supports quick field terminations in busy control panels.
The Quick Grip design delivers faster terminations, consistent torque, and reduced maintenance due to a robust nylon body and brass contacts. Over the lifecycle, this translates to lower labor costs, fewer unscheduled outages, and improved reliability in high-vibration industrial environments.
