MV Pole-Mounted Automatic Circuit Reclosers

MV reclosers up to 38kV

Nulec U-series
  • Features

    U-Series three phase pole mounted auto recloser or circuit breaker uses the latest technology in solid dielectrics, vacuum interruption and insulants. This device does not use any gas or oil insulants. 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 optimised 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
