WebAn overload relay is a device that protects an electric motor against overloads and phase failure. It senses the overloading of the motor and interrupts the power flow to the motor, thus protecting it from overheating and winding damages. Apart from overloads, it can also protect the motor from phase loss/ failures and phase imbalance.
