What is Motor Protection Relay
The function of the motor protector is to provide comprehensive protection control for the motor. Overcurrent, undercurrent, phase failure, stall, short circuit, over voltage, under voltage, leakage, three-phase unbalance, overheating, grounding, bearing wear, When the rotor is eccentric, the winding is aged to give an alarm or protection control.
