BE1-50/51B-226
Continuous Current:
2.8 Aac
One-Second Rating:
80 Aac
Time Overcurrent (51) Element
Setting the TIME PICKUP control at the minimum pickup setting places the relay in the most sensitive
state and may be used as a safety setting.
BE1-50/51B-219 Pickup
Setting Range:
0.5 to 15.9 Aac
Setting Increment:
0.1 Aac
Accuracy:
±2%, ±25 milliamperes at or above 0.5 ampere setting
BE1-50/51B-226 Pickup
Setting Range:
0.1 to 3.18 Aac
Setting Increment:
0.02 Aac
Accuracy:
±2%, ±5 milliamperes at or above 0.1 ampere setting
Dropout
Dropout occurs at 95% of pickup value.
Timing Range
0.0 to 9.9 seconds in 0.1 second steps.
Timing Accuracy
The timing accuracy is the sum of ±1 cycle, ±2%. This accuracy applies to the range of 1.3 to 40 times
tap and is for a given measured multiple of tap. The measurement of the multiple of tap has an accuracy
that is the sum of ±2%, ±25 milliamperes for the BE1-50/51B-219 and ±2%, ±5 milliamperes for the BE1-
50/51B-226.
