Correct answer

They protect against overcurrent: when current exceeds the fuse’s specified operating conditions for the required time, its element melts and interrupts the protected circuit. They limit overload or short-circuit damage; they do not prevent the fault from occurring or guarantee that no component is affected. They do not convert AC into DC. Replace a fuse with the specified type and rating, without bypassing it.
