Overview

The NSI Industries 350TP Dual Rated Turn Prevent Lug is a high-integrity electrical connector engineered for secure, low-resistance connections in industrial and commercial wiring systems. Constructed from 6061T-6 aluminum alloy, this lug delivers superior mechanical strength and corrosion resistance while maintaining excellent electrical conductivity. Its electro-tin plating minimizes contact resistance, ensuring efficient current transfer and reduced heat generation during operation. Designed for dual-rated compatibility, the 350TP accommodates both copper and aluminum conductors from 350 MCM down to 6 AWG, eliminating the need for separate inventory SKUs. The integrated turn-prevent feature on the lug's base prevents rotation during installation and under load, maintaining torque integrity and preventing loosening over time. This design element is critical in vibration-prone environments such as motor control centers, switchgear, and industrial machinery. Rated for 600V operation with a maximum of 2000V per UL486B standards, the 350TP meets stringent electrical safety requirements. Its 90°C temperature rating ensures reliable performance in demanding thermal conditions. The lug features a compact footprint with dimensions of 2.250 inches in length, 0.990 inches in width, and 1.130 inches in height, optimized for space-constrained panel layouts. Installation is straightforward with a 5/16-inch threaded mounting hole requiring 400 in./lbs. of torque, secured using a standard 5/16-inch hex wrench. The stacked wire hole design minimizes overall width while maintaining proper conductor separation. Each standard carton contains 20 units for efficient bulk handling in warehouse and procurement operations. Applications include motor starters, panelboards, transformers, and other high-current electrical assemblies where secure, maintenance-free connections are essential.
