Industrial AQ-4 Aluminum Mechanical Step Lug 600MCM-2 4 Barrel

The AQ 4-600 Aluminum PanelBoard Lug is a four-barrel, dual-rated mechanical lug for copper or aluminum conductors, capable of terminating from #2 AWG up to 600 kcmil and rated for 90°C service, making it suitable for high-current panelboard connections in electrical distribution equipment. Manufactured in aluminum, it provides four parallel termination paths with a four-barrel arrangement that supports reliable, organized terminations within compact panelboard footprints. The lug uses a 3/8 inch bolt hole for mounting and is designed to fit in standard panelboard assemblies, enabling straightforward installation alongside other AQ family components. Its overall dimensions are 3 in. long by 2-1/2 in. wide by 4-15/16 in. high, delivering a balance of capacity and space efficiency for equipment bays. As part of ABB's AQ family of dual-rated mechanical lugs, the AQ 4-600 supports copper or aluminum conductors across the specified range in distribution panels and switchgear installations.
