The motor protector provides comprehensive protection and control for the motor. It gives an alarm or performs protection control when the motor experiences overcurrent, undercurrent, phase loss, stall, short circuit, overvoltage, undervoltage, leakage, three-phase imbalance, overheating, grounding, bearing wear, rotor-stator eccentricity, or winding aging. It is an intelligent device.
