The ABB 3AUD0000003146 is an ACH580-series HVAC packaged drive delivering 300 Hp light-overload output at 460 V, with a continuous output current of 361 A per the UL listing. Input voltage range is 440 to 480 V three-phase at 50/60 Hz. The R11 frame size houses the non-fused disconnect and ultra-low harmonic filtering in a single enclosure.
The 361 A light-overload rating at 460 V governs the motor current the drive can supply continuously without derating — sized for a 300 Hp induction motor on a fan or pump load profile. The 440-480 V input range covers 460 V nominal North American distribution; the 50/60 Hz rating confirms compatibility with both 50 Hz and 60 Hz line supplies. Frame R11 defines the mounting footprint, conduit entry locations, and bus bar spacing for panel integration.
The non-fused disconnect integrated into the packaged drive provides a local lockable means of disconnection, reducing external component count in the panel.
The drive carries an active lifecycle status per the manufacturer.
