3.5.1.9 Configuration Selection 9
The EAFR-101S logic Configuration 9 is utilized in the selec-
tive arc protection solution. S2 is used for monitoring the
incoming feeder breaker compartment. S3 monitors the
reserve busbar. S4 monitors the main busbar compartment.
The contact T1 is responsible for tripping the section circuit
breaker. T2 is responsible for tripping the tie circuit breaker.
BI1 and BI2 are responsible for recognizing the incoming
circuit breaker position. BI3 receives over-current informa-
tion from the EAFR110P of the incoming feeder. BI4, BI5,
and BI6 are used for sending light information from different
locations of the busbars. BO1, BO2, and BO3 send arc fault
information to the incoming feeder units and intermediate
units. The CBFP feature is applied in this configuration.
