Thermal protectors: essential safety and protection devices

Using electrical equipment is an inevitable part of people’s lives. To prevent overheating of appliances and ensure safety, it is essential to install thermal protectors on all heat-generating equipment. Thermal protectors are also essential to prevent circuit damage by preventing the circuit from overheating.

What is a thermal protector?

A thermal protector is a safety device used to help protect electronic equipment from overheating.

Thermal protectors come in many shapes and sizes and can be used in different appliances, such as microwaves and range hoods that require different types and sizes of heaters.

How are thermal protectors used by people as safety devices?

Thermal protectors are essential safety protection devices for electrical equipment. Thermal protectors are designed to help reduce the risk of overheating and fire:

The thermal protector can automatically disconnect the circuit when the current of the electrical equipment increases and the surrounding temperature rises and exceeds the temperature set value of the thermal protector so that the electrical appliance is protected. When the device cools down to a safe temperature, the contacts can automatically close again, allowing the electrical appliance to work normally again. The thermal protector also has the function of overcurrent protection: when the circuit is short-circuited or the motor is blocked, the thermal effect is generated on the bimetallic sheet due to the rapid increase of the current, so that the thermal sensitive sheet can quickly cut off the current contact point by using the torque principle.

Therefore, thermal protectors can automatically cut off the power when appliances such as refrigerators or microwave ovens are overworked, preventing more serious things such as fire accidents.
