What does the DC fuse do?

Dc fuse is a very easy to use protection facilities, when the abnormal circuit is often accompanied by rising current, the rising current will not only damage some key equipment, but also burn the circuit, cause a fire and directly cause great economic losses. After the DC fuse is installed, when the current exceeds the current value that the DC fuse can bear, the DC fuse will melt and break itself because of the heat generated by the excessive current, killing the danger in the bud and fully protecting the line from damage.

The internal structure of DC fuse is metal with low melting point. The whole parts are installed in series in the circuit. When the current in the circuit exceeds its rated value, it will be fused because of its own heating. Dc fuses have simple internal structure, convenient installation and obvious effect. They are widely used in various power systems and power facilities. Dc fuses are also installed in many people's homes to protect home appliances from sudden damage.
