It is likely you are referring to the (or the generic GMR-32 series) 3-Phase Motor Protection Relay/Phase Controller. These devices are commonly used in industrial settings to protect motors from phase loss, phase unbalance, and incorrect phase sequence.

The gate driver PCB is epoxy-sealed. Send the unit for factory repair or replace with a new GMR32B-xxA model.

Insert only a single solid conductor into each terminal. For stranded wiring layouts, crimp a pin-type ferrule onto the wire end before insertion to avoid stray strands and high-resistance joints. 🛠️ Step-by-Step Physical Installation Chapter 11: The Emergency Bypass Sequence (this chapter

One phase is missing or there is a severe imbalance. Reverse Phase: The input phase order is incorrect. Overvoltage: Voltage has exceeded the safe limit.

⚠️ Always disconnect power before wiring. Ensure your voltage matches the device rating (e.g., 220V, 380V, 440V).

Avoid locations with high humidity, conductive dust, corrosive gases, or ambient temperatures exceeding 50°C.
