(OP)
Dear all,

For an ongoing project, I need to work with REM543 relay. So far I couldn't find any detailed information on Abb's webisite (just some general technical reference that's it).

At the moment I am particularly looking for VOC (voltage constrained overcurrent) and REF1A (restricted earth fault) functions. could anyone help me on this topic, many thanks. (by the way, I did find quite some useful file of REM543 posted here, thank you all for that)
