Remarks
Note 1.
(1) Error may occur due to waveform distortion.
(2) LR-110NAA and LR-80NAA models rated 100mA to 30A incorporate an approximate effective value
rectifying circuit.
(3) Please make sure to read the “Safety Precautions” (pp.5-8) and the “Selection Precautions” (p.9) to
assist in selecting the model and use specifications suited to the application.
The operating circuit voltage is 300V or less for the Y-2N Series, and 600V or less for the Y-N Series and L-N Series.
Note 2. For low-voltage circuits, grounding of the secondary side of the current transformer is unnecessary.
