ABB ATL402 Wire Lug

ABB ATL402 Blackburn AL COMP LUG is a color-keyed, two-hole compression lug built for high-voltage power terminations in distribution systems. It accepts 4/0 AWG stranded conductors, aluminum or copper, and, according to ABB/Blackburn catalogs, supports up to 300 kcmil size with a 1/2 in bolt hole, making it suitable for large-diameter terminations. The lug is tin-plated and finished with a white die color code to simplify identification in color-keyed installations. As part of ABB’s Blackburn Color-Keyed family, the ATL402 is designed for reliable compression connections using standard tools and dies; its aluminum construction provides corrosion resistance in outdoor or industrial environments. This 2HL lug is commonly used where a secure, easily identifiable connection is required between cables and equipment such as bus bars, transformers, or switchgear terminations in utility and industrial applications.
