Phase Monitoring Relays will protect against premature equipment failure caused by voltage faults on three-phase systems. These devices protect against unbalanced voltages or single phasing regardless of any regenerative voltages. The relay is energized when the phase sequence and all voltages are correct. Any one of four fault conditions will de-energize the relay. Re-energization is automatic upon correction of the fault. An LED indicates normal and tripped conditions. Features
Protects Against:\~Phase Loss, Phase Reversal, Phase Unbalance, Undervoltage
User-Selectable Phase Unbalance and Undervoltage Settings
User-Adjustable Time Delay Drop-Out on Undervoltage
LED Indicates Both Normal and Fault Conditions
Compatible with Most Wye or Delta Systems
Compact 8-Pin Octal Plug-In Case
