under-voltage control relay / over-voltage / single-phase / three-phase
TOV GE Digital Energy



  • Measured/monitored value:

    under-voltage, over-voltage

  • Other characteristics:

    single-phase, three-phase, time delay, modular, digital


The TOV is a versatile modular voltage relay which functions both as an over voltage and under voltage relay. Indispensable in automatically detecting under voltage events, it also functions as a fault detector with distant relays. To continue, the product serves as an over voltage detector for automatic control systems.
