Overview

The NSI Industries SL40N is a 2-hole long barrel copper stacked compression lug designed for heavy-duty electrical terminations. Engineered from high-conductivity copper tubing, this lug delivers superior electrical performance and durability for demanding applications. The SL40N is specifically designed for use with the NSI L-N Series, providing a reliable connection point for 4/0 AWG copper conductors with an expanded wire range of 4/0 to 1 AWG when used with the NSI N12ID dieless compression tool. Key features include a tin-plated finish for enhanced corrosion resistance and low contact resistance, ensuring long-term connection integrity. Each lug is marked with a die index and color-coded (Purple for SL40N) for quick identification during installation and maintenance. The SL40N is UL486A listed for 600V applications with a 90°C temperature rating, and is rated for 35KV maximum when properly installed. For applications exceeding 2000V, follow the cable manufacturer's voltage stress relief instructions. Mechanical specifications include a 1/2" bolt size, 1.75" mounting hole spacing, and a barrel length of 2.863". The lug features a 45° deep chamfer for improved wire insertion and a 9CU copper construction. Standard packaging includes 25 units per carton. Ideal for industrial electrical panels, motor control centers, and high-voltage distribution systems where reliable, corrosion-resistant terminations are critical. The SL40N's robust design and UL486A listing make it suitable for grounding and bonding applications in Class B or C building wire copper cable systems.
