Patented ROTOVERTER® tap adjustments give you control over all three phases for balancing currents. Type D ROTOVERTER® models are recommended for applications where a single load (of either single or multiple motors up to 42 HP) is operated and for non-motor load applications. 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.
