True, but (without going and looking it up again), there's mention in places along the lines of "as long as protective measures aren't affected".
There's the key point - It's mentioned only "in places." It's not a general requirement for all work. To summarize the key point on that issue from the other thread, the exemption in 1(c) for re-fixing or replacing an enclosure says that it's on condition that the circuit protective measures are unaffected and the exemption in 1(d) for providing mechanical protection is conditional upon circuit protective measures and current-carrying capacity of the cables being unaffected. But the exemption in 1(a) for replacing any fixed electrical equipment has no such condition attached - The only conditions in 1(a) are that the replacement does not involve the provision of a consumer unit or the provision of any new fixed cabling.
So it doesn't matter if a replacement RCD, MCB, RCBO, or fuse has different characteristics - It's not notifiable by way of the exemption in 1(a).
Of course, I agree that it's not a good idea for somebody to replace with a different type of device without understanding what he's doing.
