Overview

The NSI Industries LK-3 Transformer Lug Kit (SKU: LK-3) is a high-performance mechanical set-screw terminal lug kit designed for 100-167 KVA single-phase and 150-300 KVA three-phase transformers. Engineered for reliability and versatility, this kit includes terminal lugs dual-rated for both copper and aluminum cables, ensuring compatibility with a wide range of conductor sizes. The lugs are constructed from high-strength 6061-T6 aluminum alloy, providing superior electrical and mechanical performance with electro-tin plating for low contact resistance. Key specifications include a temperature rating of 90°C and a maximum voltage rating of 600V, meeting or exceeding ANSI C119.4 Class A standards. The LK-3 kit includes 3 terminal lugs for three-phase applications (2x 250 MCM-600 MCM and 1x 600 MCM-2/0) and 3 sets of hardware (3/8-16 x 2" bolts). Mounting hole spacing is NEMA 1 3/4" for standardized compatibility with transformer terminal boxes. Ideal for industrial, commercial, and utility transformer installations, the LK-3 kit simplifies wiring by eliminating the need for separate copper and aluminum lugs. The set-screw design allows for easy installation and reusability, while the dual-rated capability reduces inventory requirements and streamlines procurement. NSI Industries, a trusted US manufacturer, ensures compliance with UL486B for wire connectors, guaranteeing safety and performance in demanding electrical environments.
