Overview

The NSI Industries 3-350L4 3 Port Aluminum Dual Rated Transformer Lug is a high-strength, reusable set-screw connector engineered for superior electrical and mechanical performance in industrial and commercial transformer applications. Constructed from 6061-T6 aluminum alloy, this lug delivers exceptional durability and corrosion resistance while maintaining low contact resistance thanks to its electro-tin plating. Designed for versatility, the 3-350L4 accommodates both copper and aluminum conductors ranging from 350 MCM to 6 AWG, making it ideal for transformer terminations, panelboard connections, and heavy-duty electrical installations. Key specifications include a maximum voltage rating of 600V, a temperature rating of 90°C, and compliance with ANSI C119.4 Class A standards. The lug features two set screws per wire hole for a secure, vibration-resistant connection, and four mounting holes with NEMA 1-3/4" spacing for standardized installation. With a maximum torque value of 40 in-lbs, this lug ensures reliable performance under demanding conditions. Its compact dimensions (2.25" length x 1.94" width x 1.25" height) and hex wrench size of 5/16" make it easy to install in tight spaces. Applications include transformer terminations, panelboard connections, and heavy-duty electrical panels where dual-rated conductor compatibility and high mechanical strength are required. The 3-350L4 is a reusable solution that reduces inventory needs and simplifies maintenance in industrial electrical systems.
