Gmr-32b Phase Controller Manual

Two phases are swapped. You must swap any two of the L1, L2, or L3 input wires to fix the sequence. Phase Loss / Unbalance:

The GMR-32B Phase Controller is a DIN-rail mounted device designed to protect three-phase systems against overvoltage, undervoltage, phase loss, and sequence errors. Operating at 380VAC, it features two NO/NC contacts and LED indicators for diagnosing power issues. For more details, visit AliExpress . gmr-32b phase controller manual

Preventing dry running and reverse rotation. Two phases are swapped

Prevents damage caused by low voltage which increases heat and current draw. 3. Basic Wiring & Operation Operating at 380VAC, it features two NO/NC contacts

Integrated heatsink with forced-air cooling options. Safety Precautions

Once powered, check the status LEDs. A stable indicator usually means correct operation, while specific flashing patterns indicate faults like phase reversal or imbalance. Visual Reference
