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 “Instantaneous Current Curves (Phase)” located in the Appendix.

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