What lands on the BOM line
The ABB ACS800-04-0006-3 is a single-drive module on the ACS800-04 platform, ordered against the 380-415V supply class. It sits in the Motor Drives tier of ABB's industrial drives range — the compact wall-mount / cabinet-build form factor used where space is at a premium and a separate cabinet is overkill. For a rolling-mill floor that means a unit small enough to mount in a mill-stand local cabinet while still being a true industrial drive, not a packaged OEM inverter.
The one rating on the face of it
The only functional figure called out in the spec is the 380-415V supply class — the line voltage window the drive is built for, pointing to European three-phase industrial mains. Pairing the wrong mains voltage against a frame built for 380-415V is the classic way a replacement cook itself on first ramp. The unit is listed at 3.63 kg, so it is a one-person lift onto a backplate or DIN-bracket assembly — the kind of weight a mill electrician can handle on a mezzanine during a hot-swap without rigging.
Where this class is fitted
ACS800-04 modules are deployed as low-power industrial drives — typically smaller pump, fan, conveyor and auxiliary motor duties on a steel works — where cabinet real estate is tight and the drive needs to live in the same enclosure as contactors and PLC I/O. The 380-415V window and the compact 0006 frame point at the lower-kW end of the ACS800-04 range, so the realistic fit is fractional-to-low single-digit kW induction or permanent-magnet motor loads rather than a coiler or reeler drive. For a hot-strip mill floor this is the auxiliary drive tier — mill-table roll spindles, side-guide trim, strip-cooling fans, descaler pump duty — not the megawatt coiler or reeler drive that holds strip tension. The class is meant to live close to the motor, immune to the drive-EMI of the larger cabinets and tolerant of the radiant heat near the stands, but it is not the workhorse that pulls the strip.
