Description Of Fuse

1. When the normal working current operates at 25 ℃, the current rating of the fuse shall be reduced by 25% to avoid harmful fusing. Most traditional fuses use materials with low melting temperatures. Therefore, this kind of fuse is sensitive to the change of ambient temperature.

2. Voltage rating the voltage rating of the fuse must be equal to or greater than the effective circuit voltage. The general standard voltage rating series are 32V, 125V, 250V and 600V.

3. The resistance of the resistance fuse is not important in the whole circuit. Since the resistance of fuses with amperage less than 1 is only a few ohms, this problem should be considered when using fuses in low-voltage circuits.

4. The current carrying capacity of the ambient temperature fuse is tested at an ambient temperature of 25 ℃, which is affected by the change of ambient temperature. The higher the ambient temperature, the higher the working temperature of the fuse and the shorter its service life.
