By electromechanical, I meant a device that uses a kind of double solenoid arrangement to detect if the L and N currents are equal and open a switch contact if they are not. Jump to around 7 minutes in this video https://www.youtube.com/watch?v=gOUSDDLKICk - there is no software/microelectronic system visible. Are you referring to a different class of product? I'd be very interested to see an example of an RCD rated for use in the UK that depends on a software/microelectronic system for its core safety function.
