Overview

This ABB Aluminum Tapered Reducing Splice, SKU ATC 2 R 4, is engineered for reliable electrical connections between conductors of different sizes. It is specifically designed to join #2 stranded aluminum conductors to #4 stranded aluminum conductors. The splice features a tapered design, facilitating a secure and efficient transition. Installation requires specific dies, with this model utilizing 1/2 inch dies. The overall length of the splice is 2-15/16 inches, and its outside diameter measures 17/32 inches. Key features include an oil stop to prevent conductor contamination and an oxide inhibitor to ensure long-term conductivity and prevent corrosion. The splice is identified by a red cap and an orange cap, indicating its specific application or type. This component is suitable for applications requiring a durable and dependable splice for aluminum conductors. The UNSPSC code for this product is 39121449. The construction material is aluminum, and the splice is tapered. It is designed for reducing from a #2 stranded conductor to a #4 stranded conductor. The oil stop feature is integral to the design, as is the oxide inhibitor. The red cap and orange cap are distinct identifiers for this specific splice.
