• Indoor High Voltage Load Break Switch and Fuse Combination Apparatus

  General Description:

  FKRN24D when load break switch equip with high voltage current limited fuse(with striker), it comes into being load break switch and fuse combination apparatus,acting as protecting and control apparatus for transformers,cable and overhead wiring. When a phase or multiphase fuse fusing, load break switch automatic brake three-phase.
  These series load break switch are especially applicable in rural,urban terminal substation and prefabricated substations, as well as ring network power supply.
