Selecting an ATV930 to replace an ATV71

Is an ATV930 standard duty equal to an ATV71 by part number or kw rating?

Product Line:  

Replacing an ATV71

No, when replacing an ATV71 with an ATV930, you need to select for Heavy Duty by choosing the next size largerdrive to get the same 150% overcurrent  capacity that was provided by the ATV71.  
By default the same part number (by KW rating) would only have 120% overcurrent capacity
