Overview

NSI Industries 3/0T Aluminum Dual-Rated Single Lug (SKU: 3/0T) is a high-performance, reusable set-screw connector engineered for secure, low-resistance connections in industrial and commercial electrical systems. Constructed from 6061T-6 aluminum alloy and electro-tin plated, this lug ensures optimal conductivity and corrosion resistance when used with copper or aluminum conductors (3/0-6 AWG). The 1/4" mounting bolt provides a robust mechanical interface, while the UL 486A/B listing and 90°C temperature rating confirm compliance with stringent safety standards for 600V systems (2000V max per UL486B). Designed for versatility, the 3/0T accommodates both copper and aluminum wiring, eliminating the need for separate lugs and reducing inventory complexity. Its reusable set-screw design allows for easy installation, adjustments, and reconfiguration without compromising performance. The electro-tin plating minimizes contact resistance, ensuring stable electrical performance over time, even in high-vibration environments. With a compact footprint and durable construction, this lug is ideal for panelboard applications, motor controls, transformers, and renewable energy systems where reliability and compliance are critical. Key specifications include a 600V voltage rating (2000V transient rating), 90°C continuous operating temperature, and compatibility with 3/0-6 AWG conductors. The UL 486A/B certification (AL9CU) guarantees adherence to North American safety standards, making it a trusted choice for OEMs, electrical contractors, and maintenance teams. NSI Industries’ 3/0T lug is distributed by Gross Automation and NSI Industries, with technical support available for integration into complex systems.
