Elevators/escalators, oil pumps, cranes, and air compressors.

The relay monitors the voltage polarity; if the sequence is wrong, the internal mechanism opens the contacts to cut power. Typical Applications HVAC: Central air conditioning compressors.

A voltage imbalance between phases is a common symptom of a failing transformer or other system issues. A small voltage imbalance (e.g., 5%) can cause a large current imbalance (e.g., 50%) in a motor, leading to localized overheating and premature failure. The GMR-32B calculates the voltage imbalance percentage. If the imbalance exceeds a set limit (e.g., 10-20%), the device will trip to protect the motor.

Protect your equipment by setting a maximum current threshold. Access the internal DIP switches or digital menu. Calibrate the limit based on the load's rated amperage. 🔍 Troubleshooting Common Issues
