It's rated for 525 to 600 V input, and under UL light-overload duty it delivers 99 A output, good for 100 Hp on a 575 V motor.
The 99 A / 100 Hp figure is UL light-overload use — that's the rating that governs continuous motor duty in a North American panel. The 525-600 V input range covers 480 V and 575 V nominal systems; the drive handles both 50 and 60 Hz supply without reconfiguration. The NEMA Type12 / IP55 enclosure means it's dust-tight and hose-down resistant — suitable for washdown areas or dusty plant floors without needing a separate cabinet. The built-in disconnect and fuses simplify the install: one incoming cable, no external fused disconnect to spec and mount.
