The ABB 3AXD50000050474 is the order code for a cabinet-built LV AC drive, frame size R11, rated 450 kW normal-duty output at 820 A and 355 kW heavy-duty at 625 A on a 400 V supply. It ships with the control unit included and is configured for 3-phase input at 380...480 V, 47.5...63 Hz. The IP21 / NEMA Type 1 enclosure suits indoor installation in HVAC plant rooms or light industrial environments. Normal-duty current of 820 A covers centrifugal pumps and fans with constant torque profiles. The UL listing shows 500 Hp heavy-duty and 700 Hp light-overload, so the drive is dual-rated for North American and IEC specs.
Integration notes
The drive includes 2 analog inputs, 2 analog outputs, and 6 digital inputs / 3 digital outputs. BACnet is the listed communication protocol, which aligns with HVAC building management integration. No industrial Ethernet interface is onboard — BACnet MS/TP over RS-485 is the primary fieldbus. The control unit is included in the delivery; no separate ordering needed. Cabinet-built means the drive arrives as a self-contained assembly with power section, control, and auxiliaries wired. The R11 frame is large — expect a floor-standing cabinet, not a wall-mount. Sound level is rated at 72 dB(A), so plan for acoustic isolation if installed near occupied spaces. Ambient temperature limit is 40 °C maximum; derate above that. Operating humidity range is 5 to 95% non-condensing.
Compliance documentation
The drive carries a lithium coin cell (CR2032, 220 mAh, 3 V) for real-time clock backup. WEEE category 4 (Large Equipment) applies for end-of-life take-back. Ecodesign energy efficiency data is not provided because cabinet-built drives with conform modules are excluded from EU 2019/1781 scope per §2.3.e.
