Is it safe to replace a 0.7A 5KV fuse with a 0.65A 5KV fuse?

Question

Electronics

The microwave oven has a 0.7A 5KV fuse.
I am going to replace it with 0.65A 5KV.
Is it safe?

Answer 1

Downhill, yes, it's safe. It just might be a false positive. To increase (the ampere rating is greater than the original) - it is dangerous, it will not work on time. applies, of course, only to the tripping current of the fuse.

Answer 2

Not safe. Not all electronics will react kosherly to a sudden loss of power, especially when operating at full power. For the above reasons, it is also impossible to increase. So it is recommended to put the face value in the face value.
