Burndy NSB KK3A36U-4N Power Distribution Contacts and Accessories

Burndy KK3A36U-4N is an aluminum universal terminal lug built for power distribution, designed to accept three conductors terminated to a single 1/2 in stud within a four-hole mounting pattern. It accepts aluminum or copper conductors from 2 AWG stranded up to 600 kcmil, with tin-plated, dual-rated aluminum/copper terminals that resist corrosion and maintain low contact resistance. The lug body is crafted from a high-strength aluminum alloy and features 1.75 inch stud-hole spacing and four mounting holes, with parallel set-screw terminations for a secure clamp on each conductor. Six screws are included with the assembly to facilitate mounting in panels, distribution blocks, or switchgear enclosures. A recommended installation torque of 375 in-lbs is specified to ensure proper clamping force without over-tightening. This unit is part of Burndy’s universal mechanical lug line, designed to simplify multi-conductor connections in industrial electrical distribution while remaining compatible with both aluminum and copper wiring. Typical applications include panelboard and bus assembly connections, machine power distribution, and other settings where a compact, reliable lug termination is required.
