FAQs
Installing AH3523BK with #16-12 AWG conductors involves preparing the wire ends, stripping to the correct length, and inserting them into the back-wiring terminals per Eaton's datasheet. Ensure the conductors are fully seated to engage the Ultra grip lock. Verify the connection with a simple pull test and check that the assembly fits within the device’s approved cord diameter range (0.38–1.16 in). Use appropriate strain relief where required and follow safe lock-out/tag-out procedures during installation.
The AH3523BK supports 10 A and 20 A ratings with a voltage range of 600/250 V. This combination makes it suitable for industrial power distribution and control wiring, including higher voltage equipment in non-NEMA configurations. When selecting wiring, ensure your equipment and upstream supply conform to these ratings and maintain proper insulation, calipers, and torque for reliable terminations.
Yes. The four-pole locking design, back-wiring capability, and nylon Ultra grip housing make it well-suited for control panels and industrial machinery where a secure, vibration‑resistant connection is critical. It supports rigid mounting in harsh environments and is non-NEMA, expanding its applicability to specialized panel configurations beyond standard NEMA setups.
AH3523BK is RoHS compliant and cULus Listed, indicating restricted hazardous substances and recognized safety for North American markets. These certifications help ensure regulatory alignment for machine builders, reduce compliance risk in procurement, and simplify integration into certified systems without compromising performance or reliability.
Ultra Grip provides a secure, high‑reliability locking mechanism that resists loosening from vibration and thermal cycling. This reduces connection-related faults and maintenance intervals in dynamic applications. For lifecycle planning, select AH3523BK in environments with frequent mechanical movement or heavy equipment where stable power connections translate into lower downtime and longer service life.
