Tripping characteristic at normal overload protection
With normal overload protection (PNU b013 = 01), the tripping
current is reduced, for example, by 90 % at 2.5 Hz (a Fig. 155).
Accordingly, the tripping characteristic is offset to smaller current
values (a Fig. 158).
Tripping characteristic at adjustable overload protection
Here, you can freely select the tripping characteristic
(PNU b013 = 02) by entering the appropriate currency and
frequency coordinates under PNU b015 to b020 (a Fig. 156).
These must be within the limits shown (a Fig. 159).
The tripping curve then has the following characteristic, repre-
sented by the frequency set under PNU b018 (a Fig. 160).
