Small Motor Thermal Protector & Temperature Control Protection Switch

The smallest in the world TB02, KW-C1, 17AM is a time delay thermal protector for motor /Battery packs overheating Protection. KW-C motor thermal protector is a device that prevents a motor from overheating and catching fire by automatically turning off the motor’s electricity when it detects excessive heat. Motor thermal protectors are typically installed inside the motor. It is designed to motor achieve stable, reliable and long service life.

TB02, KW-C1 motor thermal protector is a device that prevents a motor from overheating and catching fire by automatically turning off the motor’s electricity when it detects excessive heat. Thermal protectors are typically installed inside the motor.
Thermal protectors work by monitoring the heat generated by the motor and interrupting the line power when it exceeds a safe operating temperature. Once the motor cools down, the thermal protector resets and the motor can be used again.
Other types of motor protection include:
Overcurrent protection: Protects the motor if it exceeds normal current limits
PTC thermistor sensor: A common temperature sensor used in motors that increases resistance as the temperature increases
Thermal protectors are also used in other electrical equipment, such as transformers and heating devices.
