According to standard GMR-32B installation instructions: gmr-32b phase controller manual
Typical of the GMR series, this model employs digital circuit technology to monitor the incoming three-phase power supply. Unlike simple protection devices, the GMR-32B is engineered for high precision and reliability, ensuring it does not interfere with or get affected by the load's current size, its nature, or existing current imbalances.
). If an incorrect phase sequence is detected prior to startup, the device locks out the control loop to avoid hazardous mechanical back-rotation. When a fault occurs, the GMR-32B cuts power
