The Role and Usage of Thermal Fuse
The main difference between a thermal fuse and a current fuse is that the temperature is high when the thermal fuse is blown, but the current is not necessarily high; when the current fuse is blown, the temperature is high, and the current must be high. Let’s take a closer look at each of the thermal fuse and the current fuse. effect.
Thermal fuse can sense the overheating generated during abnormal operation of electrical and electronic products, thereby cutting off the circuit to avoid fire. Commonly used: electric hair dryer, electric iron, rice cooker, electric stove, transformer, electric motor, water dispenser, coffee maker, etc. The thermal fuse cannot be used again after it is operated, and it only works once at the melting temperature.
Current fuse is also called current fuse or fuse, IEC127 standard defines it as "fuse-link", the key part (fuse) is made of silver-copper alloy with relatively large resistivity and low melting point . When the current abnormally rises to a certain height and a certain degree of heat, the fuse will fuse itself and cut off the current, thereby protecting the safe operation of the circuit.
