MV HV Fuses

Medium & High Voltage Fuses | 11kV 33kV

The ABB range of MV HV Fuses include medium voltage current limiting and expulsion fuses suitable for the electrical circuit protection of distribution transformers, voltage transformers, capacitor banks, motor circuits and installations with other switching apparatus.

Key ABB Benefits

  • Capable to control full range of MV overload currents either in combination with switching apparatus or as sole electrical circuit protection
  • Economic circuit protection devices for immediate interruption of high short circuit currents that significantly increase isolation life time
  • High mechanical and thermal resistance due to porcelain as housing materials

Key ABB Features

  • Special design fuses optimized for type of medium voltage power application
  • Two fuse housing materials are applicable – porcelain and resin-fiberglass
  • Fuse application: indoor and outdoor
