Overview

NSI Industries 4T 1 Port Aluminum Lug is a reusable set-screw connector engineered for secure, low-resistance connections in industrial and commercial electrical systems. Constructed from high-strength 6061T-6 aluminum alloy, this lug delivers superior mechanical durability and corrosion resistance while maintaining excellent electrical conductivity. The electro-tin plating ensures minimal contact resistance, critical for maintaining system efficiency and preventing heat buildup in high-current applications. Designed for dual-rated compatibility with both copper and aluminum conductors (4-14 AWG), the 4T eliminates the need for separate copper-only or aluminum-only connectors, reducing inventory complexity and installation time. With a temperature rating of 90°C and voltage rating of 600V (2200V max per UL486B), this lug meets the demands of modern electrical distribution systems where reliability and safety are paramount. The UL 486A/B listing confirms compliance with North American safety standards, making it suitable for use in panelboards, transformers, switchgear, and other critical applications. Key features include reusable set-screw design for easy installation and maintenance, electro-tin plating for enhanced conductivity and corrosion resistance, and compatibility with both copper and aluminum conductors without the need for special compounds or treatments. The compact design optimizes space in crowded electrical enclosures while providing a secure mechanical connection that resists vibration and thermal cycling. Ideal for panelboard terminations, transformer lugs, and industrial control panels, the 4T combines performance, versatility, and compliance in a single, cost-effective solution. Backed by NSI Industries' reputation for quality and reliability, the 4T is manufactured in the USA and designed to deliver consistent performance across a wide range of operating conditions. Whether used in new installations or retrofit projects, this lug provides a dependable connection that meets or exceeds industry standards for safety and performance.
