We call it an GFCI "aardlek > schakelaar" in dutch. In the UK they're usually known as RCDs - Residual Current Devices, or (less commonly) RCCBs - Residual Current Circuit Breakers. They were at one point called ELCBs (Earth Leakage Circuit Breakers) which says a lot more about how they work than "RCD". That said, I suppose RCD is a little less of a mouthful than ELCB or RCCB.
