Overview

The NSI Industries PT4/0 Stranded Bi-Metallic Pin Terminal (SKU: PT4/0) is a UL 486B-listed, 600V-rated terminal designed specifically for terminating aluminum conductors in industrial and commercial electrical systems. This terminal features a tin-plated stranded copper pin for superior conductivity and corrosion resistance, ensuring reliable electrical connections in high-vibration or harsh environments. The connector bores are pre-coated with an oxide inhibitor to prevent oxidation and maintain low contact resistance over time, critical for aluminum conductor applications where oxidation is a common failure point. Supplied with an EPDM insulating cover, the PT4/0 provides strain relief and additional protection against environmental factors such as moisture and dust. The terminal is rated for 4/0 AWG stranded aluminum conductors and is compatible with standard pin-type terminal blocks, making it ideal for use in motor control centers, switchgear, and other high-current applications. With a temperature rating of 90°C (AL9) and a maximum voltage of 600V, this terminal meets the stringent requirements of UL 486A/B standards. The PT4/0 is part of NSI Industries' PT Series, which is known for its robust construction and ease of installation. The terminal is designed for use with the N1240 crimp tool, ensuring consistent and secure terminations every time. Whether you're working on a new installation or retrofitting existing systems, the PT4/0 provides a dependable solution for aluminum conductor termination.
