Overview

The ABB 2B40X is a one-piece, two-bolt copper connector engineered for high-reliability electrical connections in utility, industrial, and commercial applications. This Type 2BX connector is specifically designed for joining conductors within precise AWG ranges, eliminating the need for spacers to ensure direct metal-to-metal contact. It supports a main wire range of 1/0 to 4/0 AWG stranded copper, making it suitable for heavy-duty power distribution and feeder circuits. The tap wire range spans from 6 AWG solid to 4/0 AWG stranded copper, accommodating branch circuits and secondary connections. The robust two-bolt fastening system, secured with 9/16-inch bolts, delivers consistent clamping force for long-term stability and low-resistance joints. Manufactured from high-conductivity copper, the 2B40X meets stringent electrical performance standards while simplifying installation with its single-piece design. Part of ABB’s Installation Products portfolio, this connector is identified by SKU 2B40X and carries the UNSPSC code 39121408, classifying it under electrical connectors for overhead and underground distribution systems. Its compact form factor and durable construction make it ideal for applications requiring durable, maintenance-free terminations in harsh environments.
