company news about Short -circuit and current overload of currents have the effect on the fuse of fuse

The short circuit of the current is the direct connection of the fire line and the zero line. Without the electrical appliances, the current circuit that is almost unblocked.

The large current passes through the fuse, and the resistance of the fuse suddenly becomes larger and generates the heat. Excessive power, that is, the current consumed current is too large. When the electrical appliances are increased, the current of the fuse is continuously increased, and the temperature of the fuse will continue to rise and eventually melted.

The principle of the two is still the same, but the cause and process are different.
