Protective Elements
50P - DEFT Overcurrent Protection
Elements
50P[1] ,50P[2] ,50P[3]
If using inrush blockings, the tripping delay of the current protection functions must be at
least 30 ms or more in order to prevent faulty trippings (applies only to devices which are
equipped with Inrush protection).
All overcurrent protective elements are identically structured.
For each element the following characteristic is available:
•DEFT (definite time).
Explanation
This element offers a criterion setting. The criterion setting tells if the threshold is based on the fundamental (Phasor)
or RMS.
For Tripping curves, please refer to the “Appendix/Instantaneous Current Curves (Phase)” section.

t = Tripping delay
I = Fault current
Pickup = If the pickup value is exceeded, the module/element starts to time out to trip .
