Product Description
Features
- Solid state reliability
- Built in Test facility
- Very low primary current sensing
- Core balance current transformer supplied along with the unit
APPLICATION
The relay used for protection of LV/MV distribution
systems requiring very high sensitivity for earth
faults.
PRINCIPLE OF OPERATION
The relay measures the earth leakage current from the
CBCT and if it exceeds the threshold, it extends a trip
signal after the operating time.
