4. Breaker Arc Protection. Preprogrammed logic is provided using fault detector 3 (F3) for the MAF fault
detector, IN1 for breaker status, and OUT4 for the arc detector output. Refer to Application Data in
this section for further details on the circuit operation.
5. Block Reclose Output. Preprogrammed logic is provided using breaker resistor protection output
(O13) to drive the block reclose (BR) output (OUT3). Refer to Application Data in this section for
further details on the circuit operation.
6. Retrip Output. A retrip output is provided to give a backup trip signal to the breaker trip coil. This can
either provide a separate path to a single trip coil or be hooked to the backup trip coil if available.
7. External Fault Trigger. The enhanced BE1-BPR relay provides the ability to save COMTRADE fault
records for twelve events in memory at one time. An external fault trigger is provided to allow other
multiple units to record the same event.
8. Alarm Output. An alarm output is provided to signal relay failure or diagnostic alarm.
