Fuses Voltage：DC and AC

What is the voltage of the fuse?
        The voltage of the fuse can be expressed as: the fuse can break the arc generated by this voltage. As a protection device in the circuit, when a fault occurs in the circuit, the fuse work is divided into two processes: "melting" + "breaking". The process of "melting" is related to the current, and the process of "breaking" is related to the voltage relation.

Difference in fuse voltage
        The fuse voltage is different from alternating current and direct current. In pure electric vehicles, it is a direct current voltage, because the inductance in the loop will generate an induced voltage at the moment when the fuse breaks, and at the same time, the influence of the inductance in the loop on the voltage arc extinguishing should be considered.The maximum voltage value that the fuse can withstand must be greater than the voltage value in the system. At the same time, there is a significant difference between AC and DC fuses in breaking extinguish the arc;
However, there is no zero-crossing point in any waveform of DC power. When breaking the DC short-circuit fault current, the arc is forced to extinguish by the rapid vaporization of the fuse and the diffusion, adsorption and cooling of the quartz sand, so it is much more difficult than breaking the AC arc.
