Restart protection device and method thereof

A restart protection device, comprising:

• a switch module, being disposed in an electric device and coupled to an external electrical power, wherein the switch module has an electrical power terminal, a first output terminal and a second output terminal, and the electrical power terminal being connected to a line terminal of the electrical power;
• and
• a restart protecting module, being disposed in the electric device and coupled to the switch module and a motor of the electric device, wherein the restart protecting module comprises:
• a relay coil, being coupled to the first output terminal by one end thereof, and the other end of the relay coil being coupled to a first input terminal of the motor;
• a first relay switch, being coupled to the second output terminal by one end thereof, and the other end of the first relay coil being coupled to a second input terminal of the motor;
• and
• a second relay switch, being coupled to the line terminal and the electrical power terminal by one end thereof, and the other end of the second relay switch being coupled to the first output terminal and the relay coil;
• wherein the first input end of the motor is further coupled to a neutral terminal of the electrical power.
