The ABB 3AUD0000004660 is an HVAC-specific drive from the ACH580 series, integrating a circuit breaker disconnect in a single enclosure. Its UL light-overload rating of 300 Hp at 361 A means it is sized for a motor load that stays below that current draw continuously — the light-overload curve is the one that governs real HVAC fan and pump duty, not the heavy-overload figure a general-purpose drive would carry. The 380 to 480 V three-phase input and 50/60 Hz frequency cover standard North American and 50 Hz global supply without a transformer.
Enclosure and environmental protection
Rated IP55 and NEMA Type12, the drive is sealed against dust and low-pressure water jets — suitable for washdown areas in food-and-bev lines or outdoor HVAC installations where the enclosure is not in direct weather. The NEMA Type12 rating adds oil and coolant resistance typical of industrial floor environments.
