Description
DESCRIPTION
3-phase monitor relay, 190-500 VAC, 8 pin plug-in 5 Amp SPDT and SPNO relay, phase loss, reversal, unbalance (alarm-no trip), over/under voltage - fixed
When the proper three-phase line voltage is applied to the unit and the phase sequence (rotation) is correct, the relay is energized after the Restart Delay is completed. A fault condition of phase loss, phase reversal or undervoltage will de-energize the relay after a delay. Re-energization is automatic upon correction of the fault condition. NOTE: the relay will not trip (de-energize) on an unbalance condition, but the LED will provide a visual indication at 6% unbalance until correction of the condition. A bi-color status LED indicates normal condition and also provides specific fault indication to simplify troubleshooting (see right).
FEATURES
Protects against phase loss, phase reversal, undervoltage & rapid cycling Indication of Phase Unbalance (Relay Does Not Trip) Universal voltage range of 190-500V—greater range that covers more global applications True RMS voltage measurement ensures accurate sensing across more applications Retains fault indication and continues monitoring all voltages even with a lost phase Full fault indication on top of unit for easy troubleshooting 5A SPDT/SPNO output provides isolated contact for alarm circuits | Learn More
