Overview

The ABB CAL 750 NTN is a tin-plated aluminum compression lug designed for terminating 700-750 kcmil aluminum-copper (AL-CU) conductors, including 636 (26/7) ACSR cables. This lug features a 7-7/8 inch barrel length and a NEMA Pad footprint of 1-3/4 inch width x 3 inch length x 1/2 inch thickness, ensuring compatibility with standard terminal configurations. The barrel measures 3-9/16 inches long, providing sufficient wire insertion depth for secure compression. Two 9/16 inch holes are positioned on 1-3/4 inch centers for bolted connections, enabling reliable electrical continuity in high-current applications. This lug is optimized for overhead distribution, substation connections, and industrial power systems where aluminum conductors are prevalent. The tin plating enhances corrosion resistance, particularly in outdoor or high-humidity environments, while the compression design ensures long-term mechanical integrity. The AL-CU compatibility allows for direct termination of aluminum conductors to copper busbars or equipment terminals without additional adapters. Installation requires industry-standard compression tools and dies, ensuring consistent crimp quality across applications. The CAL 750 NTN meets NEMA standards for pad dimensions and hole spacing, making it a drop-in replacement for existing terminal configurations.
