Not the person you are replying to, but a GFCI does not protect against overcurrent.

Well, not line-to-neutral overcurrent - which is what the person asking assumed it did.

It specifically protects against ground-path overcurrent (not ground line overcurrent - it is guarding against an undesigned path to ground, which is probably a person).
