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.
- Supply voltage : 3 Phase 415 VAC, 50 Hz (R, Y, B &N) (No auxiliary supply)
- Output Contacts : 1SPDT (nc-C-NO) Relay, Rating 5A at 250V AC
- Indications : ON( R ,Y ,B): RED LED
- Relative Humidity : 10 to 95% RH
- Mounting : Din Rail
- Dimensions : 55(W) X 75(H) X 110(D) mm.
- Keys :
- SET : SET key, Press to enter into SET Mode
- INC : Upward Arrow key, Press to increment the set point.
- DEC : Downward Arrow key, To Decrement the set point.
- Working:
- 1] If the Input supply is within the range of the fault limits then On Timer starts decrementing on display & after Set On Time over Relay will be ON
- 2] If OV, UV occurs in the supply then Relay will be OFF after the trip delay of that particular fault.
- 3] IF R ,Y ,B all phase are present than relay on condition. Controller select any one of the phase to the R, Y, B. In case of R phase are absent. Controller select Y phase. Same as another two phase work as same.
- 4] If any two phases are absent controller select 3rd phase. Same as all combinations.
- Micro controller based technology.
- Protection against under voltage, over voltage,
- All the set points settable by keys.
- Trip Delay for under voltage, over voltage is settable
- Indications for R,Y,B select phase Led.
- No separate auxiliary supply required.
