Overview

NSI Industries STL350-8 is an 8-port aluminum dual-rated transformer connector engineered for secure, low-resistance connections in transformer applications. Constructed from 6061T-6 aluminum alloy, this connector delivers superior mechanical strength and electrical conductivity while resisting corrosion. The electro-tin plating ensures minimal contact resistance, optimizing performance in high-current transformer installations. Designed for versatility, the STL350-8 accommodates conductor sizes from 350 MCM down to 6 AWG, making it ideal for both primary and secondary transformer connections. The connector features two NEMA 1/2" mounting holes for straightforward attachment to transformer studs or panels, with a mounting hole spacing of 1.75 inches. Rated for 600 volts maximum and a temperature rating of 90°C, it meets ANSI C119.4 Class A standards for reliability in industrial environments. The STL350-8 is optimized for use with copper or aluminum conductors, providing a reusable, set-screw design that ensures consistent performance over multiple installations. Its compact dimensions (11.16 inches in length, 1.00 inch in width, and 1.44 inches in height) allow for efficient use of space in tight enclosures. With a maximum torque value of 400 inch-pounds, this connector delivers a secure, vibration-resistant connection critical for transformer applications. Common applications include utility transformers, pad-mounted transformers, and secondary distribution systems where reliable, high-current terminations are required. The STL350-8 is distributed by Gross Automation and is backed by NSI Industries' commitment to quality and performance in electrical connector solutions.
