The ABB 3AXD50000417933 is a wall-mounted LV AC drive built for HVAC applications. It delivers 75 kW at 276 A in normal (light-overload) duty and 55 kW at 211 A in heavy-duty use, all on a 200-240 V three-phase supply. The R8 frame size and IP55 enclosure suit it for wall mounting in plant rooms or outdoor shelters where dust and hose-down are a concern.
The normal-use output current of 276 A (light-overload, 273 A) is the figure to size branch protection and cabling for continuous fan or pump loads. The heavy-duty rating of 211 A governs applications with higher starting torque or cyclic demand — match it to the motor nameplate if the load profile includes frequent starts or variable-torque peaks. Built-in BACnet communication means this drive talks directly to building management systems without a gateway — a time-saver for HVAC integrators who need to pull speed references and status into a BMS trend log.
I/O and control integration
The drive carries 2 analog inputs, 2 analog outputs, and 6 digital inputs / 3 digital outputs — enough for a basic pressure or temperature PID loop with remote start/stop and fault feedback. No onboard Ethernet port (0 hardware interfaces for Industrial Ethernet), so BACnet communication runs over the built-in serial or optional fieldbus adapter; plan the network topology accordingly.
Rated for a maximum ambient of 40 °C and 95 % RH, with a NEMA Type 12 enclosure. The apparent power output of 110 kVA and efficiency class IE2 place it in the mid-power HVAC segment.
