Four different layouts of the default page depending on breaker status.

mum average currents.
Example: maximum value 1000A on 1 phase, average value 700A.
From this position (closed breaker and no alarms) it’s possible to enter the main page by pushing
OK

MAX represents the maximum value among the currents (phase shown on side, I1, I2, I3 or N; this
last one only if Neutral is present); AVG instead shows the average value obtained by:
AVG =

Where “n” is the number of phase detected by the breaker, so:
4 if Neutral is present (four poles or three poles with external neutral)
3 if Neutral is absent (3 poles without external neutral)
Phases I1, I2, and I3 are always considered in the sum; Neutral only if is present.
