  • Working principle of fuse

    The working principle of fuse is mainly based on the thermal effect of current and the physical properties of metal conductor expansion due to heat.

  • Precautions for using fuses

    Choose a suitable fuse ‌: When choosing a fuse, you should choose an appropriate current rating according to actual needs. Usually, the fuse's fusing current is set to 1.5 to 2.0 times its rated current. For example, when the total power of household appliances exceeds 1100 watts, a 5-ampere fuse can be selected.
