What are the differences between industrial DC fuses and industrial AC fuses?


The functions of industrial DC fuses and industrial AC fuses are to protect electronic components from overload and short circuit damage in the event of abnormal currents in the circuit. Specifically, when the current in the circuit exceeds the rated current value of the fuse, the fuse will automatically cut off the circuit to protect other electronic components in the circuit from excessive current damage. In industrial applications, these fuses are often used as a key electronic component to prevent circuit overload and short circuits.

The difference between industrial DC fuses and industrial AC fuses lies in the type of current applied. Industrial DC fuses are mainly used in DC circuits, and the current direction is always consistent. Industrial AC fuses are mainly used in AC circuits, where the direction of the current changes during both positive and negative cycles. In addition, because the frequency of current in AC circuits is much higher than that in DC circuits, industrial AC fuses are usually more suitable for high-frequency AC circuits than industrial DC fuses. In addition, industrial DC fuses have a higher rated voltage, while industrial AC fuses have a lower rated voltage.
