Overview

The ABB 274J3-6 is a 200 Amp, 25 kV, 3-point loadbreak junction designed for reliable medium-voltage electrical distribution. This three-pole junction facilitates the connection or disconnection of loadbreak elbows under full rated current without system de-energization. Its 25 kV rating is suitable for utility, industrial, and commercial applications requiring medium-voltage power distribution. The loadbreak capability enables hot-stick operation for safe switching and maintenance without service interruption. The 3-point design ensures compatibility with standard 25 kV loadbreak elbows and bushings, providing a secure and weatherproof connection. Part of ABB’s 274J series, this junction is built for medium-voltage systems where reliability and safety are paramount. The 200 Amp rating supports continuous operation at full load in feeder circuits, transformer connections, and switchgear applications. Specifications include: Voltage Rating: 25 kV, Current Rating: 200 A, Poles: 3, Connection Type: Loadbreak, Series: 274J. Additional details from manufacturer catalog data indicate a center feed type, 4 terminals, and compatibility with line wire ranges of #6-350 MCM (line) and #8-250 MCM (load). It also features a large hub opening and is UL and utility approved.

How to Install the 274J3-6 Loadbreak Junction

Instructions for installing and connecting the 274J3-6 two, three, or four-point loadbreak junctions.

Estimated time: 45m

Tools needed:

Drill, Wrench

Supplies needed:

Mounting hardware, Grounding lug (if mounting surface is not conductive), Ground wire (14AWG minimum), Lubricant, Mating products (elbows or caps), Round yellow marker

  1. Determine mounting location and drill holes

    Select the desired location for the junction assembly. Drill holes in the mounting surface according to the dimensions provided in the diagram for J2, J3, or J4 configurations.

  2. Assemble and mount the junction

    Assemble the loadbreak junction, shield plate, and hold down brackets using the supplied fasteners. Attach the assembly to the flat mounting surface and securely tighten all fasteners to prevent movement during operation. Ensure the shield plate, hold down brackets, and conductive rubber shield are grounded. If the mounting surface is not conductive or grounded, attach a grounding lug (not provided) with one of the mounting bolts and connect a ground wire (14AWG minimum) to the lug and a ground bus.

  3. Prepare and connect mating products

    Thoroughly clean the bushing interface of any contaminants and lubricate it with the supplied lubricant. Install the mating products (insulated caps or elbow connectors) to the bushing insert, following the instructions provided with those mating products. Apply the provided round yellow marker to the mounting surface where it will be visible to the operator.

  4. Verify seating of connected products

    Confirm that the insulated cap or elbow connector is fully seated. This is indicated when no portion of the yellow band is visible when viewed from the side.
