Where it's used
Typical applications
Reduced Voltage Motor Starting
Steps down supply voltage to 50–80% to limit starting current of large squirrel-cage induction motors where DOL is not permitted.
Pumps & Compressors
Used to start high-inertia loads like centrifugal pumps, blowers, and air compressors in industrial plants and waterworks.
HVAC & Ventilation
Reduces starting torque and current surge for large HVAC fans, chillers, and cooling tower motors.
Automatic Starter Panels
Integrated into automatic reduced-voltage starter panels with timers and contactors for fully automatic starting cycles.
