company news about Does the fuse have anything to do with the voltage?

The 240V fuse is designed for equipment using 220V voltage, and the 500V fuse is designed for equipment using 380V voltage. 500V/50A fuses can be used on equipment using 220V voltage, there is no problem at all, because the fuse current is the same, both are 50A, 500V is better than 240V arc extinguishing function; 240V/50A fuses cannot be used in It is used on equipment with 380V voltage. This is because although the fusing current is the same, the arc extinguishing function of 220V cannot meet the requirements.

The so-called arc extinguishing function is the ability to quickly stop the arc after the current is too large to fuse, which is especially important when a short circuit occurs in the circuit.
