NOTES:
/1 The tolerance for each ampere setting shall not exceed ±10%.
/2 Identification marking of trip units:
Numerals indicate continuous current rating of the specific trip unit.
Letter "L" denotes that the trip units are applicable to AQB-LF226.
Letter "M" denotes calibration for applications having a high inrush current.
/3 Time shall be measured at three times the pickup current of instantaneous coil. For qualification tests only, not
for routine calibration.
/4 The LO and HI settings only are calibrated. Others are approximate.
