company news about Precautions for the use of fuses

        The fuse in the low-voltage power distribution system is an electrical appliance that plays a role in safety protection. The fuse is widely used in the protection of the power grid and the protection of electrical equipment. When the power grid or electrical equipment is short-circuited or overloaded, it can automatically cut off the circuit to avoid electrical equipment damage to prevent the accident from spreading.

        When using fuses, there are the following 4 considerations:

1. The protection characteristics of the fuse should be compatible with the overload characteristics of the protected object. Considering the possible short-circuit current, select the fuse with the corresponding breaking capacity.

2. The rated voltage of the fuse should be adapted to the line voltage level, and the rated current of the fuse should be greater than or equal to the rated current of the melt.

3. The rated current of the fuses at all levels in the line should be matched accordingly, and the rated current of the melt of the previous level must be greater than the rated current of the melt of the next level.

4. The melt of the fuse should be matched with the melt as required. It is not allowed to increase the melt at will or replace the melt with other conductors.
