Overview

The NSI Industries AL500N is a high-conductivity aluminum compression lug designed for reliable electrical connections. Manufactured from premium aluminum tubing, this standard barrel lug ensures excellent conductivity and durability. It features a center stop to guarantee proper cable installation, preventing over-insertion and ensuring a secure termination. For enhanced corrosion resistance, the AL500N is electro-tin plated, making it suitable for demanding environments. Each lug is clearly marked with its die index and color-coded for quick and easy identification, streamlining inventory management and installation processes. This lug is listed for 35kV maximum when properly installed according to cable manufacturer specifications, offering robust performance for high-voltage applications. It is rated for 90°C temperature and 600V maximum (2000V maximum per UL486B). The AL500N is cULus Listed and UL486A/B Listed for wire connectors. It is designed for use with 500 MCM aluminum conductors and features two 1/2" bolt mounting holes with a 1.750" spacing, adhering to NEMA standards. The barrel has an outer diameter of 1.320" and an inner diameter of 0.840", with a barrel length of 1.787". The tang length is 0.500" (A) and 0.700" (B), with a tang thickness of 0.060" and a mounting hole diameter of 0.508". The overall length of the lug is 4.690". The AL500N is pre-filled with an oxide inhibitor and capped with a color-coded cap for immediate, corrosion-protected installation. Compatible crimp tools include NSI N1240 and N121D. This lug is a critical component for power distribution, utility, and industrial electrical systems requiring secure and long-lasting aluminum conductor terminations. SKU: AL500N.
