Protection:

Phase Loss: Unit trips on loss of any Phase L1, L2 or L3, regardless of any regenerative voltages.

Phase Reversal (Out-of-Sequence): Unit trips if sequence (rotation) of the three phases is anything other than L1-L2-L3. It will not work on L3-L2-L1.

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 for a period longer than the adjustable trip delay. It will reset at 80% of the unbalance trip setting.

Undervoltage: Adjustable from 80-95% of the line voltage setting. Unit trips when the average of all three lines is less than the adjusted set point for a period longer than the adjustable trip delay. It will reset at +2% of the undervoltage trip setting.

Overvoltage: Adjustable from 105-120% of the line voltage setting. Unit trips when the average of all three lines is greater than the adjusted set point for a period longer than the adjustable trip delay. It will reset at +2% of the overvoltage trip setting.

Modbus TCP:

Connector: RJ45
