4. Fuse Failures

Question.6

A 24V motor controller uses a 15A automotive blade fuse on the battery input.
During a hard short event, the fuse opens, but the MOSFET is destroyed. Why?

The fuse voltage rating is incorrect
The fuse interrupt rating is insufficient
The fuse let-through energy (I²t) exceeds the MOSFET’s safe energy limit
The fuse current rating is too low
