The ABB 3AUD0000001514 is a packaged ultra-low harmonic drive with an integrated circuit breaker, purpose-built for HVAC applications. It delivers 125 Hp light-overload power at 460 V, pushing 156 A continuous (light-overload duty). That's the number that matters for sizing: it's rated for the full amp draw of a large chiller or air-handler fan motor without derating.
Input voltage range is 440 to 480 V three-phase, 50/60 Hz — standard North American 480 V distribution. The 156 A light-overload output is the continuous current the drive can supply to the motor without exceeding thermal limits in normal duty. That's not a peak or surge rating; it's the steady-state number you match to the motor FLA. IP21 protection means it's splash-resistant but not sealed. Fine for a mechanical room or electrical closet, but if this drive sits near washdown hoses or outdoors, you'll need to box it up. The integrated circuit breaker saves panel space and wiring time — one less component to spec and mount.
That means ABB still manufactures it, it's not on the chopping block for EOL. For a BOM line, this is a safe part to specify — no imminent last-time-buy pressure.
Deployment context
Panel-mount drive for HVAC central plant equipment — chillers, large fans, pumps. The integrated circuit breaker acts as both disconnect and short-circuit protection.
