Overview

The NSI Industries PT4 Stranded Bi-Metallic Pin Terminal (SKU: PT4) is a high-reliability compression connector engineered for terminating 4 AWG stranded aluminum conductors in industrial electrical systems. This terminal features a tin-plated stranded copper pin that ensures low contact resistance and superior corrosion resistance when connecting dissimilar metals like aluminum and copper. The connector bores are pre-coated with an oxide inhibitor to prevent oxidation and maintain stable electrical performance over time. Supplied with a durable EPDM insulating cover, the PT4 provides essential protection against environmental contaminants and mechanical stress during installation and operation. The PT4 is compatible with the N1240 crimp tool, ensuring consistent and secure terminations. With a pin diameter of 0.236 inches (6 mm), overall diameter of 0.630 inches (16 mm), and total length of 2.450 inches (62.2 mm), this terminal is designed for use in panelboards, motor control centers, and other industrial electrical enclosures. The tan color-coded cap indicates the #6 die size required for crimping, simplifying installation and reducing the risk of misapplication. Ideal for applications requiring reliable aluminum conductor termination, the PT4 delivers long-term performance in harsh industrial environments.
