Drop fuses are widely used in various power systems, including household, commercial, industrial and other fields. In the family, the drop fuse can protect electrical equipment from circuit overload, short circuit and other faults.

View Details

The working principle of the drop fuse is based on the fusing characteristics of the fuse

When an overcurrent occurs in the circuit, the fuse will fuse and generate an arc.
