Restrained Timing Verification (Maximum or Average Restraint)
Time Delay Range = 0 to 60,000 ms
Timing Accuracy = ±0.5% or ±1/2 cycle, whichever is greater, plus 1¼ cycles maximum for currents ≥ 5
times the pickup setting. 1¾ cycles maximum for a current of 2 times pickup. Two cycles maximum for a
current of 1.05 times the pickup setting.
