Table 9.1: Setting ranges phase current element
* Currents in the range from 0.5 to 1.5 A lead to trippings with increased trip delays (up to 50 ms).
If a C.T. current >0.5 A was present before tripping, the trip delay decreases (about 20 ms).

Table 9.2: Setting ranges earth current element
Annotation to WIP1-1:
The earth fault current element is only activated if the current flowing in at least one of the phases is higher
than the lowest adjustable threshold of the phase overcurrent element (0,5 A).
