3.5.1.5 Configuration Selection 5
The EAFR-101S logic Configuration 5 is used in the single
busbar arc protection solution. Sensors are monitoring the
section circuit breaker and the busbar between the section
circuit breaker. BI1 and BI2 receive the MT signal from
both incoming EAFR-110P relays. BI3 and BI4 receive over-
current information from both incoming EAFR-110P relays.
BO1 and BO3 send detected arc fault information from the
busbar and section CB to both incoming EAFR-110P relays.
