Burndy K3A36U-2N Mechanical Lug Terminal Block

The Burndy K3A36U-2N is a dual‑rated aluminum universal mechanical lug (KA‑U series) that accepts 2 AWG through 600 kcmil aluminum or copper conductors in a three‑conductor, two‑hole termination to a 1/2 in stud. It is constructed from high‑strength aluminum alloy and electro tin‑plated to minimize contact resistance, with three screws to secure each conductor and an Al/Cu rating for mixed‑metal terminations. The lug features 1.75 in (1 3/4 in) stud‑hole spacing and a 1/2 in stud size, enabling mounting on standard distribution hardware with two bolt holes for bolted connections. UL and CSA listings accompany this model, and it weighs about 1.1 lb, making it a suitable choice for large‑conductor terminations in power‑distribution equipment.
