Overview

The NSI Industries PTO-250 Offset Pin Terminal (SKU: PTO-250) is a high-performance, all-aluminum pin terminal engineered for reliable termination of both aluminum and copper conductors up to 250 MCM. This model features a strategically offset pin, designed to optimize space utilization in tight electrical enclosures and simplify installation, particularly in side-by-side termination configurations. The offset design is ideal for paralleling cable applications where precise conductor placement is critical, reducing installation time and improving reliability in high-density panels. The solid aluminum pin is tin-plated, providing excellent low contact resistance and superior oxidation protection. To further enhance longevity and performance, the terminal is pre-filled with an oxide inhibitor, safeguarding against environmental degradation. A convenient cover is included for rapid and secure installation, streamlining the assembly process. Key specifications include a maximum voltage rating of 600 Volts and a temperature rating of 90°C (AL9CU). It is designed for use with the N1240 crimp tool. The pin size is 3/0 AWG, with an outer diameter (O.D.) of 1.090 inches and an inner diameter (I.D.) of 0.594 inches. The overall pin length (L) is 2.620 inches, with the pin itself measuring 1.220 inches (L1) and the body length (L2) at 1.400 inches. Each standard carton contains 10 units. Choose the NSI PTO-250 for robust, space-saving terminations in demanding electrical applications where both aluminum and copper conductors need to be connected securely and efficiently.
