• Above 1,500 m (5,000 ft), contact Rockwell Automation

(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.
