Overview

The NSI Industries PTO-300 Offset Pin Terminal is a high-performance, all-aluminum compression connector engineered for terminating both aluminum and copper conductors up to 300 MCM. Designed for tight installation spaces, the offset pin design enables side-by-side terminations without interference, making it ideal for paralleling cables in industrial, commercial, and utility applications. The solid aluminum pin is tin-plated for superior corrosion resistance and low contact resistance, while the connector is pre-filled with oxide inhibitor to prevent oxidation at the connection point. A color-coded cover is included for quick identification and insulation during installation. Rated for 600 volts and a temperature range of 90°C (AL9CU), the PTO-300 meets UL486A/B standards for wire connector adapters, ensuring compliance with safety and performance requirements. The connector is compatible with standard crimp tools such as the N1240, providing a reliable and efficient termination solution. Applications include power distribution panels, motor control centers, renewable energy systems, and other high-current electrical installations where secure, long-lasting connections are critical. The PTO-300 is a dual-rated solution that eliminates the need for separate aluminum and copper terminals, reducing inventory complexity and installation time. Key specifications include a pin diameter of 0.653 inches, overall length of 2.73 inches, and a body length of 1.69 inches. The connector is supplied with a protective cover for insulation and is available in standard packaging quantities of 10 units per carton. For optimal performance, use the PTO-300 with 300 MCM conductors to ensure a secure and durable connection in demanding electrical environments.
