Product Description
The Ilsco PB4-600 is a high-capacity mechanical terminal lug from the renowned ClearChoice® series, specifically engineered for space-constrained panelboard and switchgear applications. Its innovative stacked, four-port design allows for the termination of up to four separate large conductors while occupying significantly less horizontal space than traditional side-by-side lugs.
Precision-machined from high-strength 6061-T6 aluminum alloy and electro-tin plated, this lug provides maximum conductivity and superior resistance to oxidation. The PB4-600 is AL9CU dual-rated, making it a versatile and reliable choice for both copper and aluminum conductors in heavy-duty commercial and industrial power systems.
