Overview

The ABB 60278N is a high-conductivity aluminum two-hole range-taking narrow tongue lug (SKU: 60278N) designed for demanding high-voltage electrical connections. Engineered by ABB Installation Products, this lug features a long barrel design with a 7.40-inch overall length and 3.25-inch barrel length, optimized for 500-750 kcmil conductors. The 1/2-inch bolt size and 1-3/4-inch hole spacing ensure compatibility with standard mounting hardware in panel layouts. Key specifications include a maximum voltage rating of 35kV, making it suitable for power distribution and transmission systems. The narrow 1-1/2-inch tongue width maximizes space efficiency in compact enclosures while maintaining robust mechanical strength. The barrel is factory pre-filled with an oxide-inhibiting compound to prevent corrosion and ensure long-term reliability in harsh environments. Constructed from high-conductivity wrought aluminum with an electro-tin plated finish, the 60278N provides excellent corrosion resistance and superior electrical conductivity. The yellow color-coded cap (Die Code 115H) enables quick identification and proper die selection during installation. Chamfered barrel design eliminates wire hang-ups and maximizes crimp surface area for enhanced pull-out strength. Compatible with hydraulic tools such as the TBM6H, TBM12, 13100A, TBM15I, and 21940, as well as battery-operated tools including the TBM6PCR-LI and TBM8-750 series, this lug meets UL 486 A and UL 486 B standards. The 60278N is part of ABB's range-taking narrow tongue series, designed for 90°C applications from 600V to 35kV. Consult cable manufacturer for voltage stress relief instructions with applications exceeding 2000V.

How to Install the 60278N Aluminum Lugs

This guide provides step-by-step instructions for installing and wiring the 60278N aluminum lugs for optimal electrical connections.

Estimated time: 45m

Tools needed:

Screwdriver, Wire strippers, Multimeter

Supplies needed:

Mounting screws, Terminal connectors, Joint compound, Belleville compression washers

  1. Prepare the cable

    Strip the insulation from the cable to a length of 3-3/8 inches as specified for the 60278N. Be careful not to nick the cable strands.

  2. Apply joint compound

    Smear a thin layer of joint compound onto the stripped end of the cable. Use a wire brush or emery cloth to clean the cable before inserting it into the connector.

  3. Insert and compress the connector

    Insert the cable into the connector until it stops, ensuring the insertion length matches the stripped cable length. Use the appropriate die and compress the connector on the colored bands, starting near the tongue. Ensure to perform four compressions as required.

  4. Secure the connection

    Bolt the lug to a pad using a Belleville compression washer to maintain tension. Ensure the connection is secure and free from sharp edges or burrs.

  5. Verify the installation

    Use a multimeter to check the continuity and resistance of the connection. Ensure that the connection meets electrical standards.
