U-Series Three Phase Recloser

This is a legacy product

This Product is Obsolete

Lightweight, solid dielectric with vacuum arc interruption solution for medium voltage electrical distribution networks. Provides the latest protection technology in a highly reliable, low-maintenance Automatic Circuit Recloser (ACR).

U-Series Three Phase Recloser
  • Features

    The U-Series 3 phase pole mounted auto recloser (or circuit breaker) uses the latest technology in solid dielectric epoxies, vacuum interruption, and other materials. This device does not use any gas or oil insulation. Instead, cyclo-aliphatic epoxy bushings are used to insulate the vacuum interrupters. This type of construction results in a more lightweight unit. The design has been optimized for automation, remote control, and monitoring applications and has built in current and voltage measurement for data logging.

    • Rated voltages: 15kV and 27kV
    • Rated short-circuit current: up to 12kA
    • Rated load current: up to 630A
    • 316 grade stainless steel tank
    • Solid epoxy dielectric
    • Vacuum arc interruption
    • I-terminal voltage measurement
    • Optional X-terminal voltage measurement
    • Mechanical lockout
    • 3-phase current measurement
    • 10,000 operations


    • Improve SAIDI and SAIFI indices by automatically reducing outages
    • Defer capital works by offering features that reduce network stresses
    • Easily integrated into Smart Grid applications with advanced capabilities  such as Loop Automation and Automatic Changeover
    • Flexible applications from complex substation or standalone pole mounted through powerful automation and communication features


    The U-Series 3 phase recloser is custom built for medium voltage overhead network protection. It can be installed as a substation circuit breaker or pole-mounted recloser, whatever the application calls for. With integrated automation schemes such as loop automation and automatic changeover included with the control package, the U-series recloser can be implemented in numerous installations. Some other uses for the U-series recloser are where generator control, smart grid, or feeder automation are priorities.
