The ABB 3AUD0000004294 is an ACH580-PDR series HVAC drive with an integrated disconnect switch, rated for 125 Hp light-overload use per UL at 125 A output current. It accepts 3-phase input across 500 to 600 V at 50/60 Hz and is housed in a NEMA Type3R enclosure for outdoor or sheltered installation.
The 125 A light-overload (UL) rating is the continuous output current the drive can deliver to a variable-torque load like a fan or centrifugal pump without exceeding its thermal limits. At 125 Hp, this covers a 125 Hp motor at 460 V or a 150 Hp motor at 575 V — per UL conventions, the horsepower rating is tied to the voltage class. The 500 to 600 V input range means it lands on 480 V or 575 V North American distribution systems without a step-down transformer. NEMA Type3R enclosure is rated for outdoor use — rain-tight and sleet-resistant — so the drive can be mounted on a rooftop or exterior wall without a separate weather hood. The integrated disconnect switch eliminates the need for a separate safety disconnect upstream, saving panel space and wiring time.
This part carries an active lifecycle status per the manufacturer.
