1 Measurement mode = default (depends on stage), current before fault = 0.0 × I n, f n = 50 Hz, earth-fault current 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 Start value = 2.5 × I n, Start value multiples in range of 1.5...20
