Active/Reactive/Apparent Power Ranges
The active, reactive and apparent power ranges are determined by the
voltage, current ranges and wiring as shown below:
Wiring Power range
1 φ 2W Voltage range × current range
1 φ 3W
3 φ 3W Voltage range × current range × 2

TIP
• For reactive and apparent power, the same table applies, however, the units of measurement are
different.
For reactive power: kVar
For apparent power: kVA
• If the VT or PT ratio is set to a value other than 1, multiply each value in the table by the ratio.
