Current

The initial metering display is phase 1 line current,
as illustrated in Figure 48. Press
among the three phases. Current is displayed from 0
to 999 amperes and from 1 .00 to a maximum of 999
kA. For current values less than 5% of the current
sensor rating, the displayed value is zero.

Voltage

The voltage displayed by this function depends on
how the Trip Unit was configured during Setup. If
the breaker was configured with phase-to-neutral
connec tions, the display shows individual phase volt­
ages, as in Figure 49. If the breaker was configured
with phase-to-phase connections, the display shows
voltages between the phases, as in Figure 50. Press
VALU E
to cycle through the three phase voltages.

Energy

This display, illustrated in Figure 5 1 , shows the
aggregate energy flow through the breaker. The
value is displayed from 0 to 999 kWh, then automati­
cally switches units to display 1 .00 to 999 Mwh, and
then again to display 1 .00 to 999 GWh. When 999
GWh is exceeded, the display switches back to 0
kWh. The largest negative energy value displayed is
-99 GWh.
Accumulated energy is stored in nonvolatile mem­
ory. The value in the display can be reset through
the Trip Unit keypad. To reset the energy value,
hold down the
key and press the
VALUE
The displayed energy value will reset to zero.

Total Real Power

The value displayed for total real power, illustrated
in Figure 52, represents the aggregate real power in
watts flowing through all three phases. The value is
displayed from 0 to 999 kW, then automatically
switches units to display 1 .00 to 999
