Thermal fuse consists of a sliding contact, a spring, and an electrically nonconductive thermal pellet. All of household electrical appliances whose main functions is heat generation, they are mostly equipped with temperature fuses, which can cut off the power in time when the internal parts of the machine fail, preventing further damage to electrical appliances and fire.
Thermal fuse is widely used in transformers, electric motors, electric fans, hair dryers, electric irons, rice cookers, copiers, electric stoves, chargers, power taps, water dispensers, coffee makers, etc.
1. Stable and precise operation
2. High voltage resistance
3. Small size and light weight
4. Low cost
5. There are the rate temperature value and current value marked on the shell of the temperature fuse. It is easy to identify and also very convenient to use.
How to Properly Choose Thermal Fuse?
The thermal fuse is generally connected in series in the circuit. Therefore, when you are selecting the types of thermal fuse, its rated current value must be greater than the current used in the circuit. Before selecting the rated temperature of the thermal fuse, you must understand and actually measure the temperature difference between the temperature to be protected and the location where the fuse is installed. In addition, the length of the fusing time and the availability of ventilation are also closely related to the rated temperature of the selected thermal fuse.
