The ABB 3AXD50000380800 is an LV AC wall-mounted drive for HVAC. 440–480 V 3-phase input, 20 Hp light-overload output at 27 A, frame R3, IP21 with a NEMA Type 1 enclosure.
The light-overload rating (27 A, 20 Hp) is the number that governs motor sizing on fan and pump curves. Heavy-overload would trade peak current for sustained low-speed torque; this drive doesn't carry that rating, so it's sized for variable-torque HVAC loads where the motor rarely pulls locked-rotor amps.
Product status is current and active. No LTB window, no successor part number. For BOM-freeze planning, this order code sources through standard ABB distribution against an RFQ — no broker scramble needed.
Cabinet-built mounting, IP21 / Type 1 — suitable for indoor panel installs where drips and falling dirt are the concern, not washdown. Frame R3 keeps the footprint manageable for wall-mount in a mechanical room. The 50/60 Hz frequency rating is standard for global line supplies; no de-rating needed between 50 and 60 Hz.
