That's a rather optimistic view of the effectiveness of the fuse. The
fuse is intended for personnel protection - they rarely protect the
meter from *high* currents - errant students demonstrate the art of
meter destruction to me at regular intervals.

They often blow the tracks away before the fuse blows, sometimes even
the internal shunt goes before the fuse does.

There should be HRC fuses in meters. They should blow well before the
tracks, should that is,
