Features:
Phase loss protection: When the protected line is in the running state or non-operating state, any phase failure occurs, and the delay is 2S.
Reverse phase protection: A protection measure to prevent L1, L2, L3 three-phase AC phase sequence from being connected incorrectly, delay 2S action.
Voltage unbalance protection: It refers to a protection measure that the three-phase voltage imbalance will affect the safe operation of the line. When the three-phase unbalance rate x100%>10%, the protection delay 2S action.
Overvoltage protection: It means that the voltage of the protected line is higher than the set value, and the delay is 3~8S, and the recovery is 6~20VAC.
Undervoltage protection: It means that the voltage of the protected line is lower than the set value, the delay is 3~8S, and the recovery is 3~20VAC.
