Overview

The ABB SL 350 NK is a tin-plated copper compression lug kit designed for reliable copper wire terminations up to 350 kcmil. The kit includes one straight NEMA lug (L 350 N) and one stacking NEMA lug (SL 350 N), each featuring two 9/16" holes on a 1-3/4" center for secure bolted connections. The straight lug measures 5-3/4" in length with a 1-53/64" barrel and a pad size of 1-5/16" x 3-1/8" x 5/32". The stacking lug is 5-59/64" long with a 1-15/16" barrel and a pad size of 1-5/16" x 2-13/16" x 5/32". Both lugs are UL listed and CSA certified for compliance in industrial and electrical applications. The kit also includes two 1/2" stainless steel flat washers for enhanced conductivity and corrosion resistance. Compatible with installing dies 71, 840, 18, and TX, these lugs are engineered for high-current terminations in power distribution, switchgear, and motor control centers. The tin plating ensures long-term protection against oxidation, while the compression design guarantees a low-resistance, vibration-resistant connection. Ideal for terminating stranded copper conductors in harsh environments where reliability and safety are critical.
