Release Thresholds
Before the release for tripping is given, the phase and ground currents must exceed settable thresholds. You
can set these thresholds at the following addresses:
•
1305 85 DT Iph rel. for the minimum phase current
•
1306 85 DT 3I0 rel. for the minimum ground current 3I0
Settings
The table indicates region-specific presettings. Column C (configuration) indicates the corresponding secon-
dary nominal current of the current transformer.
