company news about What are the fuse blown test methods?

     You can judge whether the fuse is blown from the following four aspects:

1 With full load CC mode aging, it is qualified if it can work normally for more than 4H.

2 Overload test, select the corresponding current load according to the chart, measure the fusing time with load and compare it with the time in the chart, if the measured time is less than the time in the chart, this parameter is qualified, otherwise it is unqualified.

3 Use the ohm gear 1x10R of the multimeter to measure, if the pointer swings to the right, it means it is good, and if the pointer does not move, it means it is broken.

4 The fusing current of a standard fuse is 2.5 times the standard current. That is to say, if there is a standard fuse with a specification of 1A, then a current of at least 2.5A needs to pass through it to make it fuse.
