■1): These items cannot be metered when VT unit (VT) is not equipped.
■2): The leakage current metering is available only when the Optional setting module type is E1 (Earth leakage protection).
■3): Include the accuracy of ZCT.
■4): 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.
■5): 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.
■6): Accuracy and cut off are defined as percentage of rated value.
■7): Accuracy is defined as percentage of true value.
■8): Power factor is measured for only fundamental wave. A waveform distortion is not included for power factor calculation.
