What the code buys you
The ABB ACS800-01-0005-3+P901 is the ACS800-01 wall-mount drive family in frame size 0005-3 with the +P901 option suffix appended, ordered as a single factory-configured line item rather than a base drive plus loose add-on. It is filed on the Motor Drives shelf under the Motors & Motor Controls category, which is the correct bucket for line-card reconciliation when a category buyer is cross-checking the BOM against the drives column. Chassis mass is listed at 4.08 kg, which puts the unit in the lift-by-hand class for cabinet installation; the panel-mount footprint and cable entries should still be cross-checked against the frame drawing before the panel cut-out is committed.
Application fit and what to think about first
ACS800-01 units are sized as low-voltage AC drives for direct-to-motor mounting inside a control cabinet, so the first sizing call is matching the frame to the motor's continuous current and the supply voltage rather than chasing peak horsepower numbers — oversizing the frame on current is cheap insurance; undersizing it on thermal margin is the usual failure mode. Before commissioning, plan for motor cable length from the start: long pigtails on an unfiltered PWM output produce reflected-wave overvoltage at the motor terminals, and on a 4.08 kg chassis of this rating the cure is a dV/dt or sine filter at the drive end, not a larger motor. Grounding and EMC practice are not optional extras on this class — keep the drive end of the motor cable shield bonded to the cabinet ground backplane at the gland plate and route control wiring on a separate tray to keep common-mode noise out of any analog reference signals riding alongside the power conductors.
Sourcing posture for the BOM line
No lifecycle status is documented for this order code, so production state is not stated here; the +P901 suffix binds the SKU to a specific factory configuration, which means quoting has to be run against the full option string and an RFQ is the right channel for availability and lead time. For a buyer holding a panel specified around the ACS880-01-11A0-5 and weighing whether this ACS800-01-0005-3+P901 can substitute, the honest answer from the order-code evidence alone is that frame class and brand line match, but the generation change is a parameter-set and wiring-dictated question that needs to be answered against the actual project documentation, not the part number.
