ROTOVERTER® Type C

Patented ROTOVERTER® tap adjustments give you control over all three phases for balancing currents. Type C ROTOVERTER® models are recommended for multiple loads of varying horsepower ratings up to 100 HP. These models are sized to the largest three-phase motor based on full-load amp (FLA) rating or total motor horsepower to be operated at one time.

Applications:

  • CNC equipment
  • Compressors: refrigeration, air conditioning
  • Pumps: centrifugal, heating systems, turbine
  • Lift stations
  • Fertilizer plants
  • Grain dryers
  • Multiple small motors
