Issue:   ATV31 (H, C or K): Do we have derate curves for 70 degrees °C ?
 
Product Line:   ATV31
 
Environment:   ATV31 (H, C or K)
 
Cause:   Temp derating
 
Resolution:   The ATV31 (H, C or K) is not expected for working to 70 degrees °C. It's clearly indicated in the ATV31 catalogue (page 10). The high limit is 60°C with derating for ATV31H (page 10). You can use the ATV31 to 70°C with the derating curves and on interpolate (page 38) but then the product will be no guaranted.
