In the 80 A/0.150 V at 50 Hz sensor applications the maximum range depends on the application
nominal:
....833 A (...31.237 mV/Hz) corresponds to 6000%I
833...1250 A (31.237...46.875 mV/Hz) corresponds to 4000%I
1250...2500 A (46.875...93.750 mV/Hz) corresponds to 2000%I
2500...4000 A (93.750...150.000 mV/Hz) corresponds to 1250%I
