Overview

The NSI Industries AL400N is a high-conductivity aluminum compression lug designed for 400 MCM conductors, offering reliable performance in medium-voltage applications up to 35 kV. Engineered from 6061T-6 aluminum alloy with electro-tin plating, this lug ensures low contact resistance and superior corrosion resistance in harsh environments. The 2-hole standard barrel design provides secure mechanical fastening with 1/2" bolt compatibility, while the center stop ensures proper cable installation depth for consistent crimping results. UL486A/B and cULus listed to 35 kV when installed per cable manufacturer specifications, this lug meets stringent safety and performance standards. The color-coded die index markings simplify tool selection and crimp verification, reducing installation errors. Ideal for utility, industrial, and commercial electrical systems requiring durable, high-ampacity terminations. Compatible with both copper and aluminum conductors, the AL400N delivers long-term reliability with a 90°C temperature rating and UL-listed voltage handling up to 600V (2000V max per UL486B). For applications exceeding 2000V, consult cable manufacturer voltage stress relief instructions. NSI Industries' compression lugs are trusted in power distribution, substations, and renewable energy installations where performance and safety cannot be compromised.
