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.
- Adjustable time delay dropout on undervoltage eliminates nuisance tripping caused by momentary voltage fluctuations.
- Voltage band provides protection to equipment required to operate within an upper and lower voltage limit, allowing the internal relay to stay energized.
- Specific customizable time delay functions allows for worry-free reliability and ease of use.
