Precautions When Selecting The Fuse Of The Drop-out Fuse

When choosing drop out fuse price fuses, special attention should be paid to product quality. The actual melting current of some drop out fuse set fuses is much smaller than the rated current. The crimping of some drop out fuse unit fuses and soft copper strands is not tight, and they can even be easily rotated. In order to reduce costs, some drop out type fuse manufacturers have insufficient or too thin cross-sections of soft copper strands at both ends of the fuses. All of these may cause the dropout fuse of transformer fuse to melt during normal operation, resulting in a power outage. In addition, in this case, since there is no short-circuit current, the expulsion drop out fuse fuse tube will produce insufficient gas, which may also cause the arc to extinguish slowly and cause a phase-to-phase short-circuit fault.
