Phase selection relay

— protective devices used when supplying a single-phase load through a three-phase network. As the name suggests, such a relay provides automatic selection of the most favorable phase; in other words, if a failure occurs on the current phase, the device switches the load to another phase, with more stable voltage indicators. Such devices are mainly intended for connecting especially important and sensitive devices that have increased requirements for voltage stability.
