Introduction
In this type of control a single over load relay is used to protect the motor.By using this over load relay provides great protection in motor.
Explanation
In this type of control circuit a single over load relay is used to protect the single phase motors.In this circuit a single phase supply comes through a magnetic contactor it provides supply to overload relay which protects the motor efficiently.If there is no problem in supply then the relay operates and gives the supply to the motor and motor starts working.But if there is an abnormal situation is created the relay operates and cut off the supply of the motor.
