Overview

The NSi Industries 258-USI Compression Connector, SKU 258-USI, is a robust electrical connector designed for reliable connections in industrial applications. Manufactured in the USA, this connector features a substantial 3 1/2-inch size, accommodating larger gauge copper cables. Its insulated throat is rated to 105°C, ensuring safe operation in elevated temperature environments. The compression connection type provides a secure and efficient termination, minimizing installation time and ensuring long-term electrical integrity. Constructed from high conductivity copper tubing and tin-plated for corrosion resistance, the 258-USI meets UL486A Listed Wire Connector standards and is suitable for use at voltages up to 600V. For applications requiring flexible or extra-flexible copper cables, such as locomotive, welding, or mining cable, the flared openings at both ends facilitate easy cable insertion and reduce stress on cable strands after installation. This connector is ideal for electrical systems where precision, durability, and consistent performance are critical.
