Overview

The ABB L 750 NB Tin Plated Copper Two-Hole Belled-End NEMA Lugs are precision-engineered connectors designed for terminating 750 kcmil copper wire in industrial electrical systems. These lugs feature a tin-plated copper construction for superior corrosion resistance and long-term conductivity, meeting NEMA standards for reliability. The two-hole design with 9/16-inch holes on a 1-3/4-inch center ensures secure mechanical fastening using standard hardware. The belled-end design simplifies wire insertion, reducing installation time and minimizing the risk of conductor damage. With a 7-inch length and a 2-13/16-inch barrel, these lugs accommodate large conductors while maintaining optimal electrical contact. The 1-3/4-inch wide x 3-1/8-inch long x 9/32-inch thick pad provides a stable mounting surface for secure attachment to bus bars or panels. Compatible with installing dies 106, 24, and 1 5/16, these lugs are ideal for high-current applications in power distribution, motor control centers, and industrial machinery where robust, low-resistance connections are critical. The tin plating enhances durability in harsh environments, ensuring consistent performance over extended service life.
