Quickly disconnect the fuse and cut off the fuse slowly
Time current characteristics are not the same, the standard of their overload fuse characteristics of the specific provisions
Reflecting the size of the impact current, more than the insurance rated current, the faster the fuse.
Slow-breaking fuses remain intact when there is a non-faulty pulse current (such as a pulse generated by a switch), and a long-term current overload is protected, and there is no such function
In addition, due to the price of slow-blown chip fuse fuse is much higher than the fuse, economic considerations have become an indirect factor in the selection.
the other hand, the use of slow blow fuse where the use of fast-blow fuse , It will often cause the boot that fuse can not work properly.
