Pickup Range
Continuously adjustable over the range defined by the style number with independent ranges and
adjustments for each phase and neutral pickup.
Pickup Accuracy
±2% or ±40 mA of pickup setting, whichever is greater.
Dropout
Within 2% of pickup.
Timing
1.5 cycles or less from onset of overcurrent condition. (30 milliseconds at 50 Hz, 25 milliseconds at 60
Hz.)
