Overview

The ABB LRT 4350 C is an Aluminum Quick Disconnect Transformer Connector from the LRT Series, engineered for high-amperage electrical connections in transformer systems. This connector accommodates a wire range from 12 to 350 AWG, providing versatility for a wide range of transformer applications. The 7-1/4-inch insulator length ensures necessary clearance and protection, while the 4-inch outlet size guarantees compatibility with standard transformer terminals. Key features include an oxide inhibitor to prevent corrosion and maintain low contact resistance in aluminum conductors, critical for long-term performance and stability in transformer systems. The robust aluminum construction ensures secure mating and disconnection, even under high-current conditions. Designed for rapid off-load connections, the LRT 4350 C uses a multicontact approach to deliver low insertion and extraction forces with minimal resistance and temperature rise. This design enables multiple connections and disconnections without degrading performance, making it ideal for applications requiring frequent maintenance or reconfiguration. The connector's unique construction includes a copper tip section and a universal aluminum crimp barrel, allowing use with both aluminum and copper conductors. This bi-metallic design ensures reliable performance across diverse conductor types, reducing the need for specialized components. Manufacturer: ABB - Installation Products. SKU: LRT 4350 C.

How to Install the LRT Series Dead Front Connector

This guide provides step-by-step instructions for installing the LRT Series Dead Front Connector, including positioning, wiring, and securing cables. Installation must be performed by trained installers in accordance with all applicable electrical codes and safety rules to prevent electric shock.

Estimated time: 30m

Tools needed:

Hex wrench, Torque wrench, Wire strippers

Supplies needed:

LRT connector body, Threaded stud, LRT insulator, Cable, Set screws

  1. Place Connector Body and Tighten Stud Set Screw

    Place the bare LRT connector body onto the threaded stud. Orient the connector to achieve proper cable training for left-hand, right-hand, or centered installation. Tighten the stud set screw to 300 in./lbs.

  2. Position the Insulator

    Position the clear LRT insulator onto the transformer bushing. Push the insulator as far back onto the bushing as possible, ensuring it is aligned for the desired left-hand, right-hand, or centered installation.

  3. Align Screw Ports

    Line up the screw ports on the insulator with the corresponding screws.

  4. Prepare for Cable Installation

    Loosen and back out the first screw to adjust the insulator's position on the bar, preparing the port for the first cable installation.

  5. Strip Cable Insulation

    Strip the cable insulation 1-1/4 to 1-1/2 inches from the end of the cable.

  6. Insert Cable

    Push the stripped cable through the cable port until the cable insulation meets the connector body.

  7. Secure Cable

    Tighten the ball bottom screw to secure the cable using a hex wrench. Apply torque according to the provided chart: 120 in./lbs (10 ft./lbs) for #12 to #4 wire, or 240 in./lbs (20 ft./lbs) for #2 to 350 MCM wire.
