Drive selection memo for a 22 kW HVAC fan or pump
The ABB 3AXD50000417889 is a wall-mounted drive sized for a 22 kW motor at 200-240 V three-phase input. Normal-use output current is 89 A; heavy-duty use drops to 18.5 kW / 75 A for tougher loads like positive-displacement pumps. Light-overload use is rated 22.0 kW / 88 A. The drive includes a control unit and is frame size R5.
The 200-240 V input and 3-phase output match North American 208/230 V commercial supply. The 89 A normal-use rating handles a 22 kW motor at full load; if your load profile is heavy-duty (e.g., high starting torque), the drive is rated 75 A continuous. Standby loss is 19 W, which matters for energy code compliance on continuously powered drives. Efficiency is IE2. Enclosure is IP55 / NEMA Type12, so it's suitable for indoor washdown or dusty environments — think HVAC mechanical rooms or light industrial floors. Ambient temperature max is 40 °C; operating humidity up to 95% RH. Wall-mounted, so no floor space needed. Built-in BACnet communication (no Industrial Ethernet interface) makes this a direct fit for building management system integration. Two analog inputs and two analog outputs cover a speed reference and feedback; six digital inputs and three digital outputs handle start/stop, fault reset, and status. The drive includes a lithium coin cell (CR2032, 220 mAh) for real-time clock backup.
