It's rated for 25 Hp at 27 A under UL light-overload conditions on a 575 V supply, with a 525 to 600 V input range and 50/60 Hz compatibility.
The 25 Hp / 27 A light-overload rating (UL) tells you this drive will handle a 25 Hp motor continuously without tripping on current, as long as the load profile stays within the light-overload duty cycle. The NEMA Type 3R enclosure means it's rated for outdoor installation — rain, sleet, and ice-resistant, but not submersible. The 525-600 V input range covers 480 V systems with a step-up transformer or direct 575 V nominal supplies common in North American industrial plants. Three-phase input, 50/60 Hz — it'll run on either frequency without reconfiguration.
