Automatically trips if the phase order (L1, L2, L3 or R, S, T) is incorrect, preventing motors from running in reverse.

If the indicator is OFF, check the L1 and L2 inputs, as these often double as the internal power supply for the device. Closed during nominal voltage and correct phase sequence

The device features a (or "reset") function. For example, if the unit trips on undervoltage at 340V, it will only automatically reset once the voltage recovers to a higher level (e.g., 345V). This prevents rapid relay oscillation when voltage is borderline, extending contactor and device life.

| Protection Type | Typical Trip Delay | Typical Reset Time | | :--- | :--- | :--- | | | 1–2 seconds | Automatic | | Over/Undervoltage | 3–8 seconds (adjustable) | Automatic (with hysteresis)| | Phase Sequence | 0.1–2 seconds | Automatic |

Solution: Check main line fuses, circuit breakers, and incoming line voltage at L1 and L2. - AliExpress Most GMR-32B units have three LEDs:

The most frequent cause of "nuisance tripping." Ensure all terminals are tightened securely.

Use insulated copper wire with a cross-sectional area of . For secure connections:
