Phase Monitor Relays (sometimes called 3 Phase Monitors, Three Phase Monitor Relays, Phase Loss Relays, Protective Relays, Motor Protection Relays or Phase Failure Relays) provide motor protection against premature equipment failure caused by voltage faults on 3 Phase systems. These devices are designed to be compatible with most Wye or Delta systems. In Wye systems, a connection to a neutral is not required. Phase Monitor Relays protect against unbalanced voltages or single phasing regardless of any regenerative voltages.
Refer to the table below for more information, then click one of the Series to see details about a specific product type. If you have any questions regarding the selection or application of phase monitor relays

Phase Loss: Unit trips on loss of any Phase A, B or C.
Phase Reversal: Unit trips if rotation (sequence) of the three phases is anything other than A-B-C.
Undervoltage: Adjustable as a percentage of nominal voltage. Unit trips when the average of all three lines is less than the adjusted set point for a period longer than the adjustable time delay drop-out.
Overvoltage: Fixed at 110% of nominal voltage. Unit trips when the average of all three lines is greater than the fixed set point for a period longer than the time delay drop-out.
Phase Unbalance: Adjustable from 2 - 10% unbalance. Unit trips when any one of the three lines deviates from the average of all three lines by more than the adjusted set point . There is also a "Disable" setting adjustment that will turn off the Phase Unbalance Protection if nuisance tripping is a problem.
