200-500VAC 50/60Hz Phase Sequence Protector 3 Phase Monitor Relay Circuit Protection

Highlights

• Voltage imbalance protection, which refers to a protective measure that will affect the safe operation of the line due to three-phase voltage imbalance.
• 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 AC 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.
• Indicated by three indicators: normal, phase loss(voltage three-phase unbalance), reverse phase.
