Fuse only functioned in steady state condition.But lightning & surge happened in transient condition.The different is times d/dt .

Some other manufacture use the fuse is to protect the current and temperature.for normal supply current is below than 2-3A.That why manufacturer will used fuse rating 10-15A.Depend on rating MOV’s.
