ABB ACS 601 - Output Current Ratings for IP54 Enclosures; Fuses

Appendix A – ACS/ACC/ACP 601 Technical Data
A-4 ACx=ACS/ACC/ACP ACS/ACC/ACP 601 Drives
• Example 2. If the ambient temperature is 122 °F, the output current
for ACx 601-0006-3 is first calculated at 104 °F (derating factor 92
% or 0.92 from Curve 2) and the result is multiplied by factor 0.65
(See
Example 1 (IP 21/22)). The output current is then 0.92 · 0.65 ·
