- A high-set overcurrent stage I>> with a setting range of 0.5...40 x I
n
. The
operation of the high-set overcurrent stage can be set out of function
- A low-set neutral overcurrent stage I
o
> with a setting range of
1.0...25.0 % I

and definite time mode of operation
- A high-set neutral overcurrent stage I
o
>> with a setting range of
2.0...200 % I
n
. The operation of the high-set neutral over current stage
can be set out of function
- Digital display of measured and set values and sets of data recorded
at the moment when faults occurs
