Overview

The ABB 755L3 600 Series Deadbreak 3-Way L-Kit is a high-capacity, medium-voltage termination solution designed for 35kV systems with a continuous current rating of 600 Amps. This deadbreak kit provides a reliable, insulated interface for branching three cables in a compact L-configuration, ideal for pad-mounted switchgear, transformers, and underground distribution systems. The kit includes all necessary components for deadbreak operation except cable adapters and compression lugs, which must be ordered separately to match specific cable diameters and termination requirements. Rated for 35kV phase-to-phase and 20kV phase-to-ground, the 755L3 supports applications in utility substations, industrial power systems, and commercial facilities where safe, insulated cable branching is required. The deadbreak design allows for load-break operations without de-energizing the system, reducing downtime during maintenance or reconfiguration. Compatible with 600 Series accessories, this kit ensures consistent performance in harsh environments, with materials engineered for UV resistance and thermal stability up to 105°C. The 3-way L-configuration optimizes space in crowded enclosures while maintaining clear phase separation. Order cable adapters (e.g., 755A series) and compression lugs (e.g., 755L series) separately based on cable size and application needs.

How to Install the 600/900 Series Deadbreak Connecting Plug

A guide for the safe and proper installation of the 600/900 series deadbreak connecting plug, including stud installation, lubrication, connection, and grounding.

Tools needed:

Torque wrench, 3/8” hex bit socket

Supplies needed:

Connecting Plug, Lubricant (supplied), No. 14 AWG (2.5mm) copper wire

  1. Prepare for Installation and Safety Check

    DANGER: Ensure all apparatus is de-energized before beginning installation. Do not touch or move energized products. Inspect all parts for damage, correct rating, and compatibility with mating parts. If supplied, remove protective shipping covers and replace with appropriate HV insulated caps or connectors before energizing.

  2. Install the Mating Stud

    If the mating plug device is not equipped with a stud, hand tighten the stud into the mating plug device. Thread the stud until the start of the flats are below the contact surface.

  3. Clean and Lubricate Components

    Clean both the connecting plug and its mating part as indicated in the diagrams. Lubricate both parts thoroughly with the supplied lubricant. DO NOT SUBSTITUTE the lubricant, as other lubricants may be harmful to the products. Ensure all surfaces remain clean during this process.

  4. Connect and Torque the Connecting Plug

    Push the connecting plug firmly into the elbow, bushing extender, vault stretcher, or elbow end module, and engage the threads. Hold the contact of the connecting plug against the contact surface of the mating part. Use a torque wrench with a 3/8” hex bit socket and tighten to 50 to 60 foot-pounds (68 to 81 newton-meters) of torque.

  5. Ground the Connecting Plug

    (If applicable) Insert one end of a No. 14 AWG (2.5mm) copper wire or equivalent through the grounding eye on the connecting plug. Twist the wire tightly, taking care not to damage the eye. Connect the other end of the wire securely to ground.
