It's UL rated for 100 Hp light-overload use at 273 A output, on a 208-240 V three-phase supply (50/60 Hz). The NEMA Type 3R enclosure means it's built for outdoor or unconditioned indoor installation — rain-tight and sleet-resistant, no additional weather cover needed. This is a single-assembly solution for a rooftop unit or air handler: the bypass lets the motor run directly off line power if the drive faults, so the building doesn't lose airflow while you troubleshoot. Lifecycle status is active — this is a current-production catalog item, not a phase-out or NRND line. The ACH580 platform is ABB's dedicated HVAC drive family, and the e-clipse bypass variant is a standard offering for packaged solutions. The 273 A light-overload rating (UL) governs the real motor load this drive can handle continuously for a variable-torque HVAC fan or pump. Light-overload (110% for 60 s) is the standard duty cycle for centrifugal loads — a 100 Hp motor at full load draws roughly that current, so the drive is sized correctly for a 100 Hp fan without oversizing. The 208-240 V input range is narrow; if your site feeds 480 V, this is the wrong unit — you'd need the 480 V variant in the ACH580 family. The NEMA 3R enclosure eliminates the need for a separate rain hood, but it's not a washdown enclosure; keep it out of direct hose spray.","metaTitle":"ABB 3AUD0000000121 ACH580 HVAC Drive, 100 Hp, 273 A, 208-240","metaDescription":"ABB 3AUD0000000121 ACH580 HVAC packaged drive with e-clipse bypass and disconnect.
