It's rated for 3-phase 380–500 V input at 50/60 Hz, delivering 60 Hp (77 A) under light-overload UL conditions and 50 Hp (65 A) under heavy-duty UL use. The drive carries NEMA Type 1 enclosure and IP21 protection, housed in a Frame Size R4.
The light-overload rating of 77 A gives headroom for variable-torque applications such as fans and centrifugal pumps, where the drive can run continuously at that current without derating. Frame size R4 determines the mounting footprint and the bus-bar / cable lug sizing — verify panel cutout dimensions against the ACS580-0P installation manual before laying out the enclosure.
