3 Set Operate delay time = 0,02 s, Operate curve type = IEC definite time, Measurement mode = default (depends on stage), current before fault = 0.0 × In, fn = 50 Hz, fault current in one
phase with nominal frequency injected from random phase angle, results based on statistical distribution of 1000 measurements
4 Includes the delay of the signal output contact
5 Includes the delay of the heavy-duty output contact
