Digital Automatic Phase Selector Relays, Manufacturer, Exporter, Supplier, Proton Power Control, Pune, Maharashtra, India

Phase Selector Relay MODEL: PR-07PC


Mounting Type : DIN Rail Mounting
'PHASE SELECTOR' is the protection relay developed by 'Proton Power Control' to provide automatic switching between the R-,Y-,B- phases for providing one of the live phase supply uninterruptedly. The unit offers following protections along with 3 digit display showing R-N,Y-N,B-N voltages in scanning mode with precise accuracy.
1] Under Voltage
2] Over Voltage
3] Phase Failure
Fault Messages will be shown after the display of R-N, Y-N & B-N Voltages.
