Automatic Phase Sequence Corrector (APSC)
Protect Your 3-Phase Equipment | Auto Correction | No Manual Wiring Change Required
An Automatic Phase Sequence Corrector (APSC) is a smart protection device that Automatically Detects and Corrects Incorrect Phase Sequence in a 3-phase power supply. It ensures that motors, elevators, air compressors, and other critical 3-phase equipment run in the correct rotational direction without manual rewiring.
It is an essential safety and convenience device for Industries, Commercial Buildings, and Sensitive Loads—especially where frequent changeovers, EB–DG switching, or portable power supplies are used.
⚙️ Key Features
- Detects incorrect phase sequence (R-Y-B order)
- Automatically corrects to standard phase sequence without user intervention
- Protects 3-phase motors from reverse rotation
- Plug-and-play unit, suitable for new and existing installations
- LED indicators for correct/incorrect sequence and status
- Fast switching (within milliseconds)
- Compact, wall-mountable or panel-mount model
- Available in contactor-based or Motorized Changeover versions
- No manual wiring change or downtime required
