NuStart 5010-21 Soft Start Control 3.5-6 Ton 208-230V 16-32A MFG#5010-21

NuStart 5010-21 Soft Start Control – 3.5 to 6 Ton (208–230V, 16–32A)

The NuStart 5010-21 Soft Start and Protection Control is designed for larger scroll compressors in HVAC/R systems. Using current-based motor control, NuStart optimizes compressor start-up by reducing inrush current and mechanical stress.

This controller helps reduce startup noise and vibration, eliminates light flicker and nuisance breaker trips, and reduces contactor arcing. It also helps protect compressors during low voltage (brownout) conditions and prevents operation beyond preset current limits.

Key Benefits:

• Reduces inrush current up to 60%

• Reduces motor torque up to 40%

• Helps prevent breaker trips at startup

• Reduces contactor arcing

• Less mechanical stress on compressor mounts and refrigerant piping

• Allows more efficient startup (may allow use of a smaller generator)

Built-In Protection:

• Reverse motor (scroll) protection

• Under-voltage (brownout) protection

• Overcurrent protection
