It is UL rated for light-overload use at 300 Hp with a continuous output current of 361 A at 460 V, 3-phase, 50/60 Hz. The frame size is R9, and the enclosure is NEMA Type 1 with IP21 protection — suitable for indoor installation where drips and falling dirt are the main contaminants, not washdown or outdoor exposure. Light-overload (Pld) typically permits 110 % current for 60 s, so the drive can handle the fan's inertia during acceleration without tripping. The 300 Hp UL output power is the mechanical shaft power the drive can deliver continuously at the rated voltage — per the datasheet, this is the UL-listed maximum for the R9 frame in this configuration. Input voltage range is 440 to 480 V, 3-phase, 50/60 Hz. The drive will accept either frequency without derating, but the output current capacity is specified at 460 V. If the line voltage sits at the low end (440 V), the drive's available output power will be proportionally lower for the same 361 A current limit. The NEMA Type 1 enclosure (IP21) means the drive is intended for indoor use where it is not exposed to hose-down or condensation. The R9 frame is a large-footprint chassis; verify the mounting footprint and clearance for the bypass contactor and disconnect handle before panel layout.","metaTitle":"ABB 3AUD0000003821 HVAC Drive, 300 Hp, 361 A, 460 V","metaDescription":"ABB 3AUD0000003821 HVAC packaged drive with e-clipse bypass and disconnect.
