[QUOTE="kakrakas, post: 554279, member: 37872"] Thanks for the reply Geoff1946. I'm actually based in Athens Greece. The reason for the installation of such protection device is mainly to have it as an extra layer of protection combined with a surge protection device that I'll be installing as part of an electrical installation upgrade. It is not uncommon for 3-phase installations losing the Neutral (either due to a connection becoming loose or due to an external fault). I've seen it happening twice in the past 3 or so years and typically it ends up destroying mainly electronic devices and A/C main circuit boards due to the loss of Neutral, so I thought it as a good practice to have one installed just in case. I too considered the option for an auxiliary power source but quickly dismissed it due to being complicated, requiring maintenance, an inverter, etc. So, it looks like the most reasonable option is to use a suitable NO relay and hope for the best.
