The thermal protectors are upgraded model type, which are produced by automatic production line and inspected by auto-temperature device. They are widely used to provide effective and reliable safety protection to motors and prevent motors from damage due to overheating. These series thermal protectors are widely applied in the industrial motor under 1HP, such as transformers, power tool, automobile, rectifiers, electro-thermal appliances, etc. With its accurate temperature control, it has double protection of current and temperature.
Thermal protection is a method of detecting over-temperature conditions and disconnecting the power to the electronic circuits. Thermal protectors are specifically made for motors. When the motor's heat rises too high, the thermal protector turns off electricity. This stops the motor from overheating and catching on fire. Thermal protectors are placed internally inside the motor.
