VOLTAGE MONITORING DEVICE

VOLTAGE MONITORING DEVICE Three Phase Sequence Relay GKRC-02FA (ENTES)
Voltage monitoring relay for the protection of three-phase networks against power fluctuations and incorrect phase sequence. Faulty alarm responses due to voltage spikes are prevented by a switching delay (0.1 – 10 s). The relay switches immediately if the voltage of a phase exceeds or falls below the nominal voltage by more than 50%.
