Overview

NSI Industries AL350-48 Aluminum Compression Lug is a high-conductivity, tin-plated connector engineered for reliable 350 MCM aluminum conductor terminations in industrial and utility applications. Manufactured from 6061T-6 aluminum alloy with electro-tin plating for corrosion resistance and low contact resistance, this lug ensures durable performance in harsh environments. The center stop design guarantees proper cable installation depth, while the color-coded barrel with die index markings simplifies crimp tool selection and ensures consistent, code-compliant installations. Key specifications include a 35KV maximum voltage rating (when properly installed per cable manufacturer instructions), 90°C temperature rating, and compatibility with both copper and aluminum conductors. The 1/2" bolt hole size and standard barrel design make it ideal for panelboard, switchgear, and transformer connections where space efficiency and reliability are critical. UL486A/B and cULus listed for wire connectors, this lug meets NEC requirements for grounding and bonding applications. Available in standard packaging, the AL350-48 supports expanded wire ranges when used with NSI N12ID dieless compression tools, offering versatility for field installations. The pre-filled oxide inhibitor and sealed end plug provide built-in corrosion protection, reducing installation time and eliminating the need for additional sealing compounds. For applications exceeding 2000V, always consult the cable manufacturer's voltage stress relief instructions to ensure long-term reliability.
