Overview

The ABB 2RF4 (SKU: 2RF4) is a high-quality nylon-insulated butt splice engineered for reliable electrical connections in industrial, commercial, and residential applications. Designed by ABB Installation Products, this splice joins two solid or stranded wires with a secure, low-profile connection, making it ideal for repairing or extending existing circuits where space is limited. The 2RF4 accommodates #4 AWG wire, with a maximum insulation diameter of 0.510 inches, and features a durable tin-plated copper construction for excellent conductivity and corrosion resistance. Key features include a brazed seam that prevents terminal barrel splitting during crimping, ensuring a consistent and secure connection. An internal wire stop guarantees proper insertion depth, eliminating the risk of over-insertion and maintaining performance integrity. The bright yellow color coding enhances visibility for easy identification and visual inspection during installation and maintenance. Its compact dimensions (1.85 inches in length and 0.52 inches in width) make it suitable for tight spaces, while the nylon insulation provides thermal stability up to 221°F (105°C). Compatible with industry-standard crimping tools such as the TBM6S, the 2RF4 ensures efficient and repeatable installations. Standard packaging includes 15 units per carton, optimized for both small projects and bulk applications.
