The fuse is composed of a melt tube, a porcelain tube, a fastening flange, a rod-shaped pillar insulator and a wiring cap. Fix the terminal caps and the melt tube at the two ends in the porcelain tube by pressing, and then fix the porcelain sleeve on the rod-shaped post insulator with a fastening flange.

The melt tube uses raw materials with high silicon oxide as the arc extinguishing medium, and uses a small-diameter metal wire as the fuse. When the overload current or short-circuit current flows through the melt tube, the fuse is immediately melted, and the arc occurs in several parallel narrow slits. The metal vapor in the arc penetrates into the quartz sand and is strongly dissociated and quickly extinguishes the arc. Therefore, this This fuse has good performance and large breaking capacity.

Install and use

1. The fuse allows horizontal or vertical installation.

2. When the data of the melt tube is inconsistent with the voltage and rated current of the line, it shall not be connected to the line for use.

3. After the melt tube is blown, the user can disassemble the wiring cap and replace the melt tube with the same specifications and performance requirements.
