Eaton AH5666BK Quick Grip Plug - UL NOM Industrial Grade

Back-wire design enables fast, secure terminations with controlled torque, reducing installation time and the risk of loose contacts in vibration-heavy equipment. The AH5666BK supports 16-12 AWG conductors and is engineered for heavy-duty industrial use, making it ideal for control panels, motor starters, and power distribution enclosures where reliability directly drives uptime. Cord-range flexibility matters in retrofit projects and OEM integrations. With a 0.22 to 0.66 inch diameter range and back-wire compatibility, technicians can terminate wires quickly without multiple ferrules or adapters. This also supports standardized wiring practices across sites, lowering training needs and accelerating field service. Durability comes from brass contact materials and a nylon body designed for harsh environments. The combination minimizes wear, resists corrosion, and maintains low contact resistance even in dusty or humid plants. These qualities help sustain electrical performance over the life of the equipment. With a 15A, 250V rating and a torque specification of 12-14 lbf-in, secure screw connections reduce thermal issues and arcing, while the two-pole, three-wire grounding (6-15P) configuration aligns with common industrial circuits and improves safety in panel assemblies. Regulatory and compliance benefits are clear. RoHS compliance, UL NOM listing, and Federal Specification Classification 6221 02 simplify procurement and audit processes. The device is designed for industrial-grade service, delivering rugged performance without compromising conformance or traceability across multi-site deployments. Packaging as core pack supports streamlined stocking and bulk orders, minimizing handling and waste. When combined with Eaton's engineering support and compatible connectors, the AH5666BK offers a compelling total-cost-of- ownership advantage for OEMs and maintenance teams seeking reliable, long-life power connections.
