Overview

The ABB U5 Series Aluminum Compression Pin Terminals, SKU U 5 U 4-2 1/2, are engineered for reliable electrical connections in aluminum conductor applications. Manufactured by ABB - Installation Products, these terminals are designed for use with aluminum conductors ranging from 2 AWG Solid to 3 and 4 AWG Stranded, as well as 4 AWG ACSR (Aluminum Conductor Steel Reinforced). The pin terminal features a solid copper pin with a length of 2-1/2 inches, providing a secure and durable connection point. Installation is facilitated using specific installing dies, including 5/8, BG, and TU options, ensuring proper crimping for optimal conductivity and mechanical strength. Each terminal is pre-filled with an oxide inhibiting compound, which is crucial for preventing corrosion and maintaining low resistance over the lifespan of the connection, especially in aluminum conductor systems prone to oxidation. The U5 Series is a testament to ABB's commitment to providing robust and efficient connection solutions for electrical infrastructure and industrial applications. These terminals are ideal for use in power distribution, transmission, and industrial wiring where dependable aluminum conductor termination is paramount. The compression connection method ensures a permanent, low-resistance joint that can withstand mechanical stress and environmental factors. The material composition of aluminum for the barrel and solid copper for the pin is selected for its conductivity and compatibility with aluminum conductors, minimizing galvanic corrosion potential. Verify compatibility with your specific conductor size and installation tooling before application. The UNSPSC code for this product is 39121409.
