Siemens 3UG4631-1AW30 Monitoring Relay, Single Phase Voltage Monitoring, Screw Terminal, 1 CO Contacts, 0.1-60VAC/DC Measuring Range, 0.1-30V Hysteresis, 0-20s Delay Time, 24-240VAC/DC Auxiliary Voltage
- 3 INDICATORS-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. Indicated by three indicators: normal, phase loss(voltage three-phase unbalance), reverse phase.
- PHASE LOSS PROTECTION-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.
- REVERSE PHASE PROTECTION-Reverse phase protection, a protection measure to prevent L1, L2, L3 three-phase AC phase sequence from being connected incorrectly, delay 2S action.
- VOLTAGE IMBALANCE PROTECTION-Voltage imbalance protection, which refers to a protective measure that will affect the safe operation of the line due to three-phase voltage imbalance.
- IDEAL FOR-Widely used in air compressors, electric motors, distribution boxes, water pumps, oil pumps, central air conditioning units, etc.
