My understanding is a GFCI is an American term for an RCD or an RCBO?

My (UK) fridge is on a standard 30A breaker which itself comes off a single 80A/30mA RCD which was presumably part of the regs at one point. It's never tripped. All the RCBOs I've seen are 30mA too.

(I have some sockets on a 10A breaker downstream of this which have tripped - the house needs a total rewire, total bunch of bodge jobs from the previous owner, including a 13A socket in the bathroom)

Does a GFCI typically have a lower trip that 30mA?

Yes. USA GFCI's are like RCD's, but trip at 5mA. Thats why they false trip pretty often.
