Product Description
The Square D A600CT is an industrial-grade mechanical terminal lug engineered for high-capacity power distribution. A staple in Square D panelboards, switchgear, and neutral assemblies, this lug is precision-machined from high-strength 6061-T6 aluminum alloy. It is specifically designed to handle massive main feeders, supporting conductors up to 600 kcmil (MCM) while maintaining a compact footprint for internal equipment mounting.
Every A600CT is electro-tin plated to ensure exceptionally low contact resistance and to provide a permanent barrier against atmospheric and galvanic corrosion. As a dual-rated (AL9CU) connector, it is UL-listed for the safe termination of both copper and aluminum conductors.
