The ABB 3ABD00039441-D is a low-voltage AC industrial single drive module. It delivers 355 kW normal-duty output power at 370 A, fed from a 525 to 690 V three-phase supply. The module is rated for heavy-duty use at 315 kW / 325 A and light-overload use at 355 kW / 360 A.
The normal-duty 370 A output current (In) is the headline number for continuous motor loads. The heavy-duty 325 A (IhD) applies when you need sustained torque at low speed or frequent starts — think conveyors or crushers. Light-overload 360 A (IlD) covers applications like fans or centrifugal pumps where the peak demand is brief. All three are rated at the same 525-690 V input range, so the choice between them is about the duty cycle, not the supply.
Physical and environmental fit
Frame size R10 defines the module's footprint and mounting pattern — critical for panel layout when you're retrofitting into an existing MCC or drive cabinet. The IP20 degree of protection means it's intended for installation inside an enclosure where tools are required to access live parts. The NEMA Open Type enclosure classification aligns with that: no additional weatherproofing, but suitable for a clean, dry electrical room.
