Some precautions in the use of fuse
1. The rated voltage of the fuse should be greater than the input voltage of the protected circuit.
2. The rated current of the UL specification fuse is determined under laboratory conditions. The actual use should be less than 75%of the nominal value.
3. The rated current of the IEC specification fuse tube can be used at 90%or 100%of the nominal values in actual use.
4. Under different use of the environmental temperature, the working life of the fuse is different, the higher the temperature, the shorter the life of the fuse; when the actual selection, you need to refer to the working environment temperature
5. The separation capacity of the fuse tube is proportional to its volume, which is inversely proportional to the rated voltage.
6. The pulse impact of more than 100,000 times, the pulse I2T that protects the circuit should be less than 20%of the fuse pipe's rated I2T.
