company news about Common causes of fuse blowing

(1) There are short circuits in the circuit, and the short -circuit current is too large.

(2) The load power is too large and the current increases. The ability of the fuse can normal through the current, and the circuit fuse can be burned.

(3) Unstable voltage, frequent changes in the power of the electrical appliances, which causes frequency changes in the current of the fuse to burn the fuse.

(4) The fuse itself is aging, and the use time is too long, because the fuse has a certain resistance, the current is heating, it will become thinner and thinner, the resistance becomes larger and larger, and eventually causes the fuse to burn.

(5) The fuses exist in the air for a long time and are oxidized.
