It's common to use round pin sockets for things like table lamps plugged
in to a lighting circuit. Normally round pin 2 or 5 amp. If you used a 13
amp socket, some idiot might plug in a heater etc.

You could always connect it via a 3A FCU. That might stop it tripping
the lighting MCB if overloaded, most times anyway.

Type B & Type II MCBs are far faster than fuses.

That does really depend on the level of fault current. Fuses get faster
with larger currents, whereas the mechanical speed of a MCB is limited.

Probably all of them.
