Product Description

Phase and Voltage Control Relay


The relay is used to protect different types of electrical machines and equipments especially the electrical motors against the harm of abnormal operation conditions such as overvoltage,undervoltage, phase failure,incorrect phase sequence and phase unbalance.

1. Microprocessor control technology
2. Single modules, 18mm wide
3. Supply voltage measurement(True RMS)
4. Overvoltage,undervoltage,phase failure, incorrcet phase sequence, phase unbalance.
5. Threshold value and delay adjustment by knobs
6. 3phase 3wire: 208VAC,220VAC,240VAC,380VAC,400VAC,415VAC 460VAC,480VAC
     3phase 4wire: 220VAC,230VAC,240VAC
7. LED indication for power supply and relay status
8. Din-rail mounting
