Introduction
Fuses protect all types of equipment and switchgear from overcurrent: Overcurrent may cause the following hazards:
--- Thermal damage to wires or bus bars;
---Metal vaporization;
---Gas ionization;
---Arc, fire, explosion;
---Insulation damage:
In addition to personal injury, shutdowns caused by overcurrent and repairs to damaged equipment may cause huge economic losses:
Nowadays, the fuse is a universal overcurrent protection electrical appliance: In terms of eliminating or suppressing the effects of overcurrent, fuses provide a very
Economical and effective solution:
