Breaker control CBXCBR and breaker failure protection CCBRBRF are always
associated with one set of phase current inputs. In REB611, the current inputs are
phase differential currents, that is, a vector-sum of all phase feeder currents that flow
in or out of the same bus. The bus differential current is not a feeder phase current and
is normally zero. If a bus fault occurs and any phase differential protection picks up,
all breakers that connect to the bus should be tripped.
As there is only one set of breaker control and breaker failure protection, and multiple
breakers are associated with the bus protection especially when multiple source
feeders are connected to the bus, these functions must be dealt with application-
specifically.
Since the differential current cannot simply reflect any source breaker, the breaker
control and breaker failure protection should be turned off.
