Reset
Integrating:
Simulates the disk reset of electromechanical relays and begins
when the current decreases below 95% of pickup. The
Characteristic Curves chapter illustrates the integrating reset
characteristic curve and equation.
Instantaneous: Reset occurs within 16 ms of when the current decreases below
95% of the pickup level.
Instantaneous Overcurrent A (50-A) Element
Pickup
Setting Range:
2 to 99 Aac
Setting increment: 1 Aac
Accuracy: Sum of
±2% and ±25 mAac
Dropout
Dropout occurs at 95% of pickup value.
Time Delay
Switch selectable with no intentional delay (SW3-2 OFF) or a fixed delay of 100 ms (SW3-2 ON). The
Characteristic Curves chapter illustrates the characteristic curve for the 50-A and 50-B elements.
Instantaneous Overcurrent B (50-B) Element
Pickup
Setting Range:
1 to 15.9 Aac
Setting increment: 0.1 Aac
Accuracy: Sum of
±2% and ±25 mAac
Dropout
Dropout occurs at 95% of pickup value.
Time Delay
Fixed at no intentional delay. The Characteristic Curves chapter illustrates the characteristic curves for
the 50-A and 50-B elements.
Reset Characteristic
Resets within 16 ms of when sensed current decreases below the pickup level.
Current Sensing Input
Continuous Rating: 14 Aac
∗
1 Second Rating: 400 Aac
∗ Continuous rating is 14 Aac for temperatures up to 45°C. See Figure 1 for de-rating curve.
