Description

1. Version I (square round hole type) used for cable or busbars passing through, generally for monitoring purpose.

2. Version II (horizontal square hole type) used for 1-3 busbars passing through, generally for monitoring purpose.

3. Version III (vertical square hole type) used for 1-3 busbars passing through, for monitoring, electric metering (0.2 class accuracy), 
being used in systems of a high secondary resistance, and in relay protecting.

4. Version (round hole type) used for cables with large diameters, electric systems of high secondary resistances, 
and acting as zero sequence instrument transformers.
