Drive selection memo for HVAC duty
The ABB 3AXD50000417841 is a wall-mounted HVAC drive, rated 5.5 kW normal use at 24.5 A on a 200-240 V three-phase supply. Heavy-duty use drops to 4.0 kW at 16.7 A. IP55 with NEMA Type 12 enclosure suits washdown or dusty mechanical rooms; wall-mount frame R2 keeps the footprint compact. BACnet communication is onboard — no option card needed for BAS integration. The drive includes a control unit, so the BOM line is self-contained. Standby loss of 14 W matters for continuous fan operation where idle power adds up across a bank of drives.
I/O and fieldbus slice
Two analog inputs and two analog outputs handle pressure or temperature transducers; six digital inputs and three digital outputs cover start/stop, fault reset, and status feedback. No industrial Ethernet interface is present — this is a BACnet MS/TP or native BACnet drive, not a PROFINET or EtherNet/IP variant. If the BMS requires BACnet/IP, verify the controller gateway or consider the Ethernet option slot. The drive accepts 47.5-63 Hz input, so it works on 50 Hz or 60 Hz mains without reconfiguration. Efficiency is IE2 class — adequate for HVAC where part-load efficiency is more critical than full-load IE4.
Lifecycle and compliance posture
No end-of-life notification or last-time-buy window is in effect. For a BOM that needs a qualified HVAC drive with BACnet, this part is a stable line item — no requalification trigger from obsolescence.
