Temperature fuse is also called thermal fuse (national standard gb9816.1-2013) is a temperature sensing circuit cut-off device. The temperature fuse can sense the overheating generated in the abnormal operation of electrical and electronic products, so as to cut off the circuit to avoid fire. It is commonly used in: hair dryer, electric iron, electric rice cooker, electric furnace, transformer, motor, water dispenser, coffee pot, etc. the temperature fuse can not be used again after operation, and can only be melted Operate once under the off temperature.

Chinese Name: temperature fuse foreign name: thermal links, also known as thermal fuse link, belongs to the category of temperature sensing circuit cutting device, organic type, square shell type temperature fuse, etc

There are many forms of temperature fuse, and the following three are more common:

First: Organic temperature fuse

The second type: porcelain tube type temperature fuse

The third type: square shell temperature fuse

It can be divided into 73 degrees 99 degrees 77 degrees 94 degrees 113 degrees 121 degrees 133 degrees 142 degrees 157 degrees 172 degrees 192 degrees 216 degrees 227 degrees 240 degrees 70 degrees 77 degrees 84 degrees 92 degrees 95 degrees 105 degrees 110 degrees 115 degrees 121 degrees 128 degrees 130 degrees 139 degrees 141 degrees 144 degrees 152 degrees 157 degrees 169 degrees 184 degrees 185 degrees 192 degrees 216 degrees 227 degrees 228 degrees 240 degrees 250 degrees 280 degrees 320 degrees

Temperature fuse can sense the overheating caused by Bai in the abnormal operation of electrical and electronic products, and cut off the circuit from Du to avoid fire. Dao is commonly used in: hair dryer, electric iron, electric rice cooker, electric stove, transformer, motor, water dispenser, coffee pot, etc. after the operation of temperature fuse, it can not be used again, but only act once at the fusing temperature.

Current fuse is also called current fuse or fuse, which is defined as "fuse link" and key part (fuse) in iec127 standard It is made of silver copper alloy with high resistivity and low melting point. When the current abnormally rises to a certain height and heat, the fuse will fuse and cut off the current, so as to protect the safe operation of the circuit.

The same point: both of them fuse when the temperature is too high

Difference: when the temperature fuse is blown, the temperature is high, but the current is not necessarily high; when the current fuse is blown, the temperature is high, and the current is also high
