How to choose a thermal fuse?

Fuse is also called thermal fuse, and the selection of thermal fuse is based on the four points of rated operating temperature, measured operating temperature, holding temperature, and maximum limit temperature. Let me explain these four points to you.

1.Rated operating temperature: When only the detection current of the thermal fuse is not greater than 10mA as the load, the temperature at which the thermal fuse changes its electrical state, then the temperature tolerance at this time is within the range of +0 and -10°C.

2. Measured operating temperature: the temperature when the thermal fuse is operating in the oven where the temperature rise rate is 0.5~1℃/min and the detection current is not higher than 10mA.

3. Maintaining temperature: The maximum temperature that the thermal fuse can withstand without changing the state of electro-oxygen flow when the thermal fuse is connected to the rated current and can be continuously maintained in the on-state for 168 hours.

4.The highest limit temperature: the temperature fuse can be at the highest temperature. In this high temperature state, the temperature fuse has changed the electrical and oxygen conductivity, and the temperature fuse lasts for 10 minutes at this high temperature without damaging the mechanical properties and electrical properties of the product. Oxygen characteristics.

Through the above four points of knowledge, I believe that everyone will be more aware of the choice of thermal fuse.
