The charging pile fuse is based on the fact that after the current exceeds the specified value for a period of time, the heat generated by itself melts the melt, thereby disconnecting the circuit; a current protector made using this principle. Fuses are widely used in low-voltage power distribution ... Read More

The charging pile fuse is mainly composed of three parts: melt, shell and support, among which the melt is the key element to control the fusing characteristics. The material, size and shape of the melt determine the fusing characteristics. Melt materials are divided into two categories: low melting ... Read More

In the process of circuit breaking by fuse, arcing will occur in the gap between melt disconnection due to the existence of circuit voltage, and the high quality fuse should avoid this kind of flying arc as much as possible. After the fuse breaks the circuit, it should be able to withstand the ... Read More
