Voltage Monitoring Relays

Voltage Monitoring Relays

Eaton’s Voltage Monitoring Relays are solid-state protective relays that automatically operate when one or more phases of the three-phase supply is lost, or when the phase sequence is reversed. These relays monitor three-phase voltage and respond to abnormal or overcharge conditions, a pre-selected undervoltage threshold, and a pre-selected percent of phase imbalance to protect equipment against voltage fault conditions.
