Overview

The NSi Industries 256-I is a 2-1/2 inch steel compression connector designed for secure, high-performance connections in industrial electrical systems. Engineered for copper cables only, this UL486A-listed connector operates at 600V and 90°C, meeting rigorous safety and performance standards. Its insulated throat provides electrical hazard protection, while the continuous flare on the connector end ensures smooth cable insertion for flexible and extra-flexible cables such as locomotive, welding, and mining cables. The tin-plated steel construction delivers corrosion resistance, extending service life in harsh environments. With NEMA-spaced mounting holes (1¾"), the 256-I integrates seamlessly into industrial machinery, conduit systems, and power distribution networks. Compatible with NSI N12ID dieless compression tools, it supports expanded wire ranges for versatility. Trust NSi Industries for reliable, code-compliant connectors that reduce installation time and maintenance costs.
