3 Phase Circuit Voltage Monitoring Relay Failure Sequence Protector H
- Voltage imbalance protection, which refers to a protective measure that will affect the safe operation of the line due to three-phase voltage imbalance.
- Indicated by three indicators: normal, phase loss(voltage three-phase unbalance), reverse phase.
- The protector base adopts 35mm rail type or device type, and has two screw hole structures inside, which can be directly installed separately or HT35 rail.
- Reverse phase protection, a protection measure to prevent L1, L2, L3 three-phase phase sequence from being connected incorrectly, delay 2S action.
- 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.
