What it is and why it lands on the buyer's desk
The ABB ACS800-02-0170-5+H358+P901 is a wall-mount, low-voltage AC drive from the ACS800-02 family, built for cabinet-side mounting next to the motor it feeds rather than for a freestanding floor enclosure. The +H358 and +P901 suffixes on this order string are factory option codes; ordering the exact composite is what reproduces the as-shipped configuration, because ACS800-02 drives are optioned, not option-less. Listed mass is 90.53 kgs, so the unit is a two-person lift at install and needs an anchored wall or back-plate rated for that static load plus vibration from the cooling fan path. Class placement is Motor Drives under ABB's Motors & Motor Controls line, which is the right search context for a sourcing desk pulling spares for an existing ACS800-02 cabinet.
What the ratings mean for the application fit
On the ACS800-02 platform the 0170-5 frame size is the heavy end of the wall-mount series, so it pairs with motors where continuous current and torque are the working point, not light-duty fan or pump trim — confirm the duty cycle against the frame's continuous and overload curves before quoting a retrofit. Wall-mount drives at this mass class live close to the motor, which is the right call for keeping motor-cable length short and reflected-wave dV/dt on the winding insulation within reason; long pigtail runs between this drive and the motor are the usual culprit when an insulation failure shows up months later. EMC behavior at this class is set by ABB's standard ACS800-02 filtering stage plus the +H358 / +P901 options, so the panel builder still needs to land the cabinet ground bond at the drive's PE terminal first and route the motor cable away from signal runs — line-side filtering only works when the cabinet ground is short and flat.
Sourcing posture for a legacy frame
For panel builders and MRO desks still running an ACS800-02 cabinet, the buying question is whether the exact composite ACS800-02-0170-5+H358+P901 reproduces the as-built option set — that is what an RFQ against this order code settles, with the +H358 and +P901 options carried in the line item so the replacement arrives configured. If the panel is up for a planned refresh rather than a spare, the ACS880-01 and ACS580-01 families are the generation to evaluate against; that is a cabinet-layout and parameter-mapping project, outside this order code's BOM line.
