SPECIFICATIONS
BE1-BPR Breaker Protection Relays have the following features and capabilities.
Current Sensing Four isolated inputs with a maximum burden of less than 0.1 ohm.
5 Ampere CT Maximum continuous current: 20 amperes. Maximum one second current:
500 amperes.
1 Ampere CT Maximum continuous current: 4 amperes. Maximum one second current:
80 amperes.
Current Detector Instantaneous Fault Detector (50/60 Hz RMS Filter Type 1 and 3):
Pickup Time 1¼ cycle maximum for current 125% greater than pickup.
Moving Average Window Fault Detector (50/60 Hz RMS Filter Type 2):
Maximum pickup time is (Window_size/C_PM + 1¼(cy)), where
Window_size = Filter window size in cycles (Range 1 - 100) and C_PM =
Current Pickup Multiple
Current Detector Instantaneous Fault Detector (50/60 Hz RMS Filter Type 1 and 3):
Dropout Time Dropout/pickup ratio: 90%, typical. One-quarter cycle (4.2 milliseconds @
60 hertz) from the time the current falls below and stays below 25% of the
RMS level or 1¼ cycle from the time the RMS current signal decreases to
less than 75% of pickup.
Moving Average Window Fault Detector
(50/60 Hz RMS Filter Type 2):
Maximum dropout time is (Window_size-(Window_size/C_PM) +1¼ (cy)),
where Window_size = Filter window size in cycles (Range 1 - 100) and
C_PM = Current Pickup Multiple level before dropout.
Current Pickup Range Three independent settings, selectable as three-phase or neutral
Instantaneous Fault Detector (50/60 Hz RMS Filter Type 1 and 3):
(5 ampere CT) - 0.25 to 9.99 amperes selectable in 0.01 increments
(1 ampere CT) - 0.05 to 2.00 amperes selectable in 0.01 increments
Moving Average Window Fault Detector
(50/60 Hz RMS Filter Type 2):
(5 ampere CT) - 0.05 to 1.00 amperes selectable in 0.01 increments
(1 ampere CT) - 0.01 to 0.20 amperes selectable in 0.01 increments
Current Pickup Accuracy Instantaneous Fault Detector (50/60 Hz RMS Filter Type 1 and 3):
(5 ampere CT) - ±2% of pickup setting or ±0.05 ampere (whichever is
greater)
(1 ampere CT) - ±2% of pickup setting or ±0.01 ampere (whichever is
greater)
