Overview

The ABB Installation Products A 125-406 V5 is a tin-plated aluminum mechanical lug designed for secure, dual-rated connections in electrical installations. Rated for copper and aluminum conductors from #14 AWG to 1/0 AWG, this lug ensures reliable performance in branch circuits, panelboards, and equipment wiring. The 90°C temperature rating meets NEC requirements for standard installations, while the 3/8" bolt provides a robust mechanical connection. The left-side set screw (7/16-20 UNF-2A x 3/8") allows for tool-free tightening, reducing installation time. With a pad thickness of 3/16" and a 13/32" diameter hole, it accommodates standard mounting hardware. The 1-1/2" length and 13/16" width/height dimensions ensure compatibility with tight panel spaces. CSA/UL listed for safety and reliability, this lug is ideal for commercial, industrial, and residential applications where durable, code-compliant connections are required. The tin plating enhances corrosion resistance, extending service life in harsh environments.
