1)
Set Operate delay time = 0,02 s, Operate curve type = ANSI de nite time, Measurement mode = default (depends on stage), current before
fault = 0.0 x 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
2)
Includes the delay of the signal output contact
3)
Maximum Pickup range = 2.5 x In, Pickup range multiples in range of 1.5 to 20
