Overview
The NSI Industries PTO-400 is a dual-rated, all-aluminum offset pin terminal engineered for the termination of 400 MCM aluminum or copper conductors. The offset pin design provides exceptional versatility in tight spaces and simplifies side-by-side parallel cable installations. The tin-plated aluminum body delivers low contact resistance and long-term oxidation protection, while the factory-applied oxide inhibitor ensures a reliable, maintenance-free connection. Pink color coding corresponds to a 300-size crimp die (CD20-2CR), eliminating guesswork during installation.
