Overview

The NSI Industries 350L2 is a single-port panelboard lug engineered for secure, high-capacity terminations in electrical distribution systems, switchgear, and industrial panelboards. Constructed from 6061-T6 aluminum alloy, it delivers superior mechanical strength and corrosion resistance while maintaining low contact resistance through electro-tin plating. This dual-rated lug accommodates copper or aluminum conductors ranging from 350 MCM down to 6 AWG, reducing inventory requirements for contractors and maintenance teams. The NEMA-standard 1.750-inch mounting hole spacing prevents rotation and ensures a stable, vibration-resistant connection. Rated for 600V (2000V max per UL486B) and operating reliably at 90°C, the 350L2 meets stringent performance demands in high-current applications. Its panelboard-style design integrates seamlessly with standard NEMA mounting configurations, making it ideal for panelboard lug applications where secure, long-term terminations are critical. The electro-tin plating minimizes heat buildup and oxidation, enhancing electrical efficiency and service life. With UL 486A/B listing, this lug is a dependable choice for industrial and commercial electrical installations requiring durable, high-capacity conductor terminations.
