Oumefar AC 480V 3 Phase Circuit Voltage Monitoring Relay 5 Indicators Heavy Duty Phase Failure Sequence Relay Stable for Air Compressors-Fast Shipping

Description

The base of the protector adopts a rail type with two screw holes, which can be directly installed separately or mounted on the HT35 rail.

Use 5 indicators to indicate: normal, phase loss (voltage three-phase unbalance), reverse phase, overvoltage and undervoltage.

Phase loss protection means that when the protected line is in the running state or non-operating state, any phase failure occurs, and the delay is 2S.

Overvoltage protection 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.

Reverse phase protection, a protection measure to prevent L1, L2, L3 three-phase AC phase sequence from being connected incorrectly, delay 2S action.
