DESCRIPTION
3-phase monitor relay, 400 VAC, 8 pin SPDT relay, phase loss, phase reversal, undervoltage with adjustable undervoltage trip
When the proper 3-phase line voltage is applied to the unit and the phase sequence (rotation) is correct, the relay is energized. Any one of three fault conditions will de-energize the relay after a delay. Re-energization is automatic upon correction of the fault 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 Separate 208, 240, 400, 480V & 575V versions True RMS voltage measurement ensures accurate sensing across more applications Retains fault indication and continues monitoring all voltages even with a lost phase Best-in-class phase loss protection Full fault indication on top of unit for easy troubleshooting
