That could be a fuse in a spur. Or a 2A MCB.
If you want to.
But you don't have to.
AFAIR, the sparks here (including me) reckon it's OK to have a 2A socket on a 5/6A circuit in the same way that a 13A socket goes on a 30/32A circuit.

To be honest I personally think its ok too, apart from the fact that I suspect it is non compliant. That is until a casual comment of 'it trips if I have any lights on when I'm ironing' revealed this:
I have changed a few 2A sockets to 5A where money grabbing companies fail them on PIR's so I know there is significant discrepancy on opinions.
Although I have some reservations, in essence its ok to have 13A sockets on 32A [or bigger!] OCD's as the outlet is [or should be] protected by the fuse in the plug, my main concern here is the blase attitude of adding a DSSO on a 2.5mm spur for 2 large loads [typically washing machine & dishwasher] but this is adequately covered in so many other threads.
