▌Protection Function:

Phase Loss Protection:
When any one of the three phases is open-circuited, the protection action time is less than 1 minute.
Phase Imbalance Protection:
When the three-phase imbalance K1 or K2 is greater than 10%, the protection action time is less than 10 minutes.
Overcurrent Protection:
When the motor is stalled, the protector operates with a delay of (±1s).
Overvoltage Protection:
When the power supply voltage Ue > 120%, the protection action time is less than 1 second.
Undervoltage Protection:
When the power supply voltage is (60%-75%) Ue, the protection action time is less than 60 seconds.
Reset Function:
Manual reset via the stop button.
Overtemperature Protection:
When the soft starter operates at an excessive temperature, the soft starter will automatically shut down and report a soft start overheat fault.

▌Application Range:

• Fluid Handling (Pumps & Fans):
  Used in water treatment, HVAC, and industrial ventilation to minimize mechanical stress and improve energy efficiency during startup.

• Material Transport (Conveyors & Belt Drives):
  Ensures gradual motor speed increase, reducing equipment wear and enhancing operational efficiency.

• Compression Systems (Compressors):
  Reduces inrush current and mechanical stress in air conditioning, refrigeration, and industrial compressor applications.

• Mixing & Agitation (Mixers & Agitators):
  Provides smooth, controlled startups in food processing, chemical facilities, and wastewater treatment, minimizing vibration and improving efficiency.
