What you're holding
The ABB ACS355-03E-44A0-4+J404 is a 3-phase input general-purpose drive sitting in the Motor Drives class on the ACS355 platform, with the +J404 option suffix added to the base 03E-44A0-4 order string. It carries the ASEA BROWN BOVERI house naming on the nameplate and falls under the broader ABB brand for sourcing and warranty. Class placement puts it under Motors & Motor Controls, in the Drives subcategory, specifically Motor Drives — a general-purpose VFD slot rather than a dedicated machinery or servo line.
What the listed rating actually tells you
The spec bundle carries the part number, the 3-phase input topology, and a single physical mass figure of 5.00 kgs — everything else you'd normally weigh (current frame, voltage class, horsepower, overload rating, switching frequency, I/O map, fieldbus option) sits with the +J404 option bundle and the base drive family, not on this stripped line. The 5.00 kgs figure is a handling and panel-load datum for the installer or panel builder — one person can lift it into a cabinet, but the enclosure still needs to support it on the backplate. It is not a sizing number for the motor it controls.
Class context and where it fits
As an ACS355 platform drive with 3-phase input, the typical fit is general-purpose variable-speed control of standard induction motors in light-industrial panels — the kind of slot an integrator fills on a conveyor, fan, pump, or mixer where ABB's standard drive firmware and I/O map are wanted. The +J404 suffix is an option-code addition on top of the base 03E-44A0-4 string; option codes on this platform typically resolve to a specific firmware, I/O, or fieldbus configuration that has to be specified at order time so the panel build and the parameter set line up on commissioning day.
Sourcing posture
No lifecycle status entry travels with this part on record, so production state is not asserted here — the safest procurement move is to quote to order against an RFQ and let the channel confirm whether the current build, a carry-over build, or a last-time-buy window is in play for the ACS355-03E-44A0-4+J404 string. For an MRO planner holding a spare or filling a BOM line, the practical path is to specify the full order code including the +J404 option on the RFQ so the build matches the original panel's option stack rather than accepting a default-config drive and discovering it at commissioning.
