Note:
a Neutral current accuracy for internal sensor (4 pole) breakers.
Please note that maximum and minimum values are held
until reset using PXPM or the display. Demand values
are on a configurable fixed or sliding window of 5 to 60
minutes.
The power and energy metering and the protection func-
tions are calculated with the convention that power flow is
from line to load through the circuit breaker. This assumes
the top side conductor to be the line side. If the distribution
system is configured such that the bottom side is the line
side, the power values will indicate reverse power. This
can be changed by using the display and navigation button.
Navigate to the Edit Settings menu and under Power Feed,
select Forward or Reverse.
