What it is
The ABB ACS800-ITTU1-0005-5+P901 is an ACS800-ITTU series industrial drive in the three-phase motor drive class, sitting in the Motors & Motor Controls / Drives / Motor Drives line and described by the manufacturer as a 3 HP drive unit. Drive weight is listed at 6.80 kgs, which is the figure to plan around for cabinet handling, lifting, and panel shipping weight when this frame goes on a swap or new build. The P901 option suffix on this code is the point that typically separates the ACS800-ITTU base inverter from a configured-with-options build — confirming the suffix against the PO line is the first thing a receiving tech should do before the drive goes on the wall.
Where this class is used
ACS800-platform drives of this family run three-phase induction and permanent-magnet motors in process lines, pump and fan skids, and material-handling cells, sized to the motor's kW/HP at the panel's supply voltage. On the commissioning side, the installer works through the drive's keypad or commissioning tool to set motor data, ramp profiles, and I/O mapping — the typical commissioning path on an ACS800 — before handing the drive to the controls integrator for fieldbus drop-in.
Sourcing posture
RFQs should include the full order string ACS800-ITTU1-0005-5+P901 with the P901 option suffix spelled out and the nameplate HP rating noted, so the quote line matches what's on the panel and the replacement decision can be made against a confirmed variant.
