■1): "○", "×" and "△" represents "available", "not available" and "available on phase 1 to phase 3", respectively.
■2): Including the accuracy of ZCT.
■3): When using at 3φ3W system, the apparent power is calculated by (√3/2)×(I1×V12 + I3×V23).
Therefore, the accuracy may not be ensured in the unbalanced circuit.
■4): Rated voltage of measurement is 440V. Rated power and energy of measurement is √3×In×440V.
Rated earth leakage current of measurement is IΔn_max (=10A). Rated power factor is 90 degrees.
■5): Accuracy and cut off are defined as percentage of rated value.
■6): Accuracy is defined as percentage of true value.
■7): Power factor is measured for only fundamental wave. A waveform distortion is not included for power factor calculation.
