Overview

The ABB K651CPSP is a 15/25kV, 600 Amp deadbreak connecting plug engineered for medium-voltage cable systems. This factory-assembled unit features a non-removable stud, eliminating field assembly errors and ensuring consistent performance. The deadbreak design enables safe, de-energized connections, making it ideal for underground distribution networks, switchgear connections, and transformer terminations. With a 600 Amp continuous rating, it supports high-current applications in utility, industrial, and commercial power systems. Compatible with ABB's 600ATM assembly tool, the K651CPSP guarantees proper installation and long-term reliability. The plug meets ANSI/IEEE Standard 386 and is designed for 15/25kV class equipment, providing a secure, moisture-resistant connection. Use it in vaults, manholes, and pad-mounted transformers where space and safety are critical. The factory-assembled stud reduces installation time and minimizes human error, while the deadbreak feature allows maintenance without de-energizing the system. The K651CPSP is constructed with 100% peroxide-cured EPDM materials for durability in outdoor and indoor environments. It supports 8.3kV phase-to-ground and 14.4kV phase-to-phase operating voltages for 15kV class, with a 95kV BIL impulse withstand rating. For 25kV class, it supports 16.2kV phase-to-ground and 28kV phase-to-phase, with a 140kV BIL rating. The plug is rated for 25kA symmetrical momentary current for 10 cycles.

How to Install the 600/900 Series Deadbreak Connecting Plug

This guide provides step-by-step instructions for the safe installation and connection of the 600/900 Series Deadbreak Connecting Plug, an accessory for power distribution systems.

Estimated time: 30m

Tools needed:

Torque wrench, 600ATM or 3/8” hex bit socket

Supplies needed:

Connecting Plug, Lubricant (supplied, DO NOT SUBSTITUTE), No. 14 AWG (2.5mm) copper wire or equivalent, Mating plug device

  1. Prepare for Installation and Inspect Parts

    DANGER: Ensure all apparatus is de-energized before beginning installation or removal of parts. This product must be installed only by competent personnel trained in high voltage electrical equipment. Inspect the connecting plug and its mating part for any damage, verify their ratings, and confirm compatibility. Check that all package contents are complete and undamaged.

  2. Install Stud into Mating Device (If Required)

    If the mating plug device (e.g., elbow, bushing extender, vault stretcher, or elbow end module) is not equipped with a stud, hand tighten the stud into the mating plug device. Thread the stud in 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 thoroughly. Apply the supplied lubricant to both parts as indicated in the diagram. WARNING: DO NOT SUBSTITUTE the supplied lubricant, as other lubricants may be harmful to the product.

  4. Connect and Torque the Connecting Plug

    Push the connecting plug firmly into the mating part (elbow, bushing extender, vault stretcher, or elbow end module) and engage the threads. Ensure the contact of the connecting plug is held against the contact surface of the mating part. Using a 600ATM or a 3/8” hex bit socket with a torque wrench, tighten the connection to 50 to 60 foot-pounds (68 to 81 newton-meters) of torque.

  5. Install Grounding Wire (If Applicable)

    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.
