Overview

This connector features a tin-plated finish for superior corrosion resistance, ensuring extended service life in harsh environments such as locomotives, welding, mining, and diesel systems. The insulated throat is rated for 105°C and 600V, meeting NEC and industry safety standards for damp or wet locations. Designed with flared openings at both ends, the 255-SRTI simplifies cable insertion for flexible and extra-flexible conductors while reducing pressure on cable strands post-installation. This design minimizes chafing and breakage from cable movement. The positive center stop ensures proper alignment during installation, and NEMA-spaced mounting holes (1¾") allow secure attachment with standard tools. Compatible with copper cables only, this connector supports Class B or C building wire applications. When installed with the NSI N12ID dieless compression tool, it offers an expanded wire range. The 255-SRTI is distributed by Gross Automation and listed under UL486A with a temperature rating of 90°C and voltage rating of 600V.
