The 3 Phase Overload Relay is a solid state protection relay. It measures current and provide protection against overload, current unbalance & SPP faults. This is based on Microchip, with a high degree of programmability. The Meter’s supplied preprogrammed for operation and can be directly installed.
- Input Supply : 3 Phase 415 V, 50 Hz AC supply.

2] Enclosure : 190 (W) X 130 (L) X 70 (H) mm.
3] Terminal : Screw ON Terminals. - KEYS :
SET : This key is used to change the controller from RUN mode to FUNCTION mode for parameter setting
UP Arrow: This key is used to Increment the parameter value.
Down Arrow: This key is used to Decrement the parameter value & reset fault if present. - LED Indications :
1. Fault (Red): Fault LED is ON when any faults (Over Load, Current Unbalance & SPP) occurs.
2. ON (Green): This LED is ON when motor drawn Current & turn OFF when any above fault occurs.
- WORKING :
In normal running mode (if display current enable is selected), display shows
1. r-a--R phase Current--
2. y-a--Y phase Current--
3. b-a--B phase Current--
- Note :
1. Calibration setting is for Factory setting only.
2. For manual reset fault press Decrement Key.
3. Password 5 is applicable only when display current enable mode is disable.
4. To Load default parameter Press INC key on power ON.
