Rated for 10 Hp light-overload use at 30.8 A on a 208-240 V three-phase supply, it handles 50/60 Hz motors.
The 30.8 A light-overload current at 10 Hp is the UL-listed figure — that's the sustained output you can count on for a variable-torque load like a fan or pump. The 208-240 V input range covers standard North American three-phase services; the drive will ride through a 208 V service without derating. NEMA 3R is the key callout for a paper mill or outdoor installation: it survives rain, snow, and hose-down cleaning, but it's not submersible or dust-tight like a 4X would be.
