# Electronic – Is this fuse time-current curve wrong

fuses

In it is this:

These curves don't seem correct. Notice that the curves for fuses with >= 800mA asymptotically approaches a value that doesn't match their rated current.

Is there some assumption I am unaware of? Or is this graph in error?

This isn't the case with other curves that I see, but those were fast-acting fuses and these are time-delay fuses.

For comparison these are the curves for the fast-acting Bel 0DAC/0ADAP fuses and the curves do approach the rated current.
