Entes GKRC-20F Voltage Monitoring Relay SPDT-CO 8A

Voltage monitoring relay for the protection of one-phase and 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 to 10s). The relay switches immediately if the voltage of a phase exceeds or falls below the nominal voltage by more than 50%.
