Overview

The ABB Bi-Metal Pin Connector (SKU: 61955) is a high-integrity termination solution engineered for reliable aluminum-to-copper conductor transitions in 600V electrical systems. Designed to convert a 300 kcmil aluminum cable into a 4/0 AWG copper pigtail, this connector eliminates the need for oversized aluminum terminations while ensuring long-term electrical integrity. The bi-metal construction—aluminum body with copper wire—mitigates cold flow and oxidation risks inherent to aluminum conductors, providing a stable, low-resistance connection critical for industrial, commercial, and utility applications. Key specifications include a pin diameter of 0.523 inches (13.28 mm) and a pin length of 1.464 inches (37.19 mm), with an overall body length of 2.050 inches (52.07 mm). The connector features a die code of 71H (red color-coded) for tooling compatibility and a tin-plated finish for enhanced conductivity and corrosion resistance. The barrel is prefilled with joint compound to prevent oxidation and ensure consistent performance over time. This connector is ideal for applications requiring aluminum cable termination into copper-only lugs, such as motor control centers, panelboards, and distribution equipment. Its compact design and color-keyed system simplify inventory management and tooling selection. Trust ABB Installation Products for precision-engineered termination solutions that deliver durability and performance in demanding electrical systems.
