(1) For units connected in parallel, derating is required proportionally to the fluctuation (dispersion) of inductances of AC line reactors connected to phases.
(2) At the rated current of the 8720MC-RPS units.
(3) Applies to 400V rms AC (or 200V rms AC). If you use the unit continuously at a voltage lower than stated, derating is required.
