You guys might help. An FCU has a cartridge fuse. Is a form of FCU available that has a micro circuit braker in it, so it can be instantly be reset rather than replace a fuse? I have seen some with RCDs in them, single socket sized, freely available.

No, and there would be no reason to make such a thing.
Why do you think that a fuse protecting a device might blow so often that an "instantly resettable" device might be necessary??
Probably due to selecting an incorrect fuse rating, not taking into account inrush/starting currents etc.

Taylortwocities, a radial off a ring. The micro breaker protects the 2.5mm cable. The radial will have many sockets for low current appliances like computers, chargers, printers, etc. If someone plugs in say a 3kW kettle by mistake and the cable limit is exceeded the breaker trips. The user will know why and reset and not need to find a fuse and know why as the breaker can be seen to have tripped.
Why not design and install the electrical installation properly so it takes into account the loads expected to be used?
Echo the husky, you never got it. An analogy. A ring with a 32A breaker that has 10 sockets outlets off it. Quite normal isn't it? If someone plugs in 10 3kw heaters the breaker will trip. The circuit is not expected to have 10 3Kw heaters, yet it is totally capable of having 10 plugged in. A radial for computers is not expected to have a 3kW kettle, but in case.....
A micro breaker can be fitted but in one of the small CU boxes which are still rather biggish.

What colour is the sky where you are?
I have seen installations with upwards of 10 DBs in a space not much bigger than an average house. What's your point?
It's called discrimination. However, there is clearly a reason the device you seek is not made. I have no doubt manufactures have the technical ability to do it. After all, the majority of an MCB is just plastic moulding.
In case what?
What point are you trying to make?
Where and why? What cable would the breaker be protecting?
Plugtops (the screwed on top of the plug) don't have fuses. Plugs do.
