What you're actually sourcing
The ABB ACH580-01-07A2-4+B056 is a configured ACH580-01 frame-1 drive from the ACH580 series, identified on the listing as an inverter in the Motor Drives class. The +B056 suffix is part of the configured order code, not a separately ordered accessory — the drive ships from the factory with whatever option B056 carries (commonly a documentation or firmware variant on the ACH580 platform), so the full string ACH580-01-07A2-4+B056 is what has to land on the PO line. At 2.48 kg this is a wall-mount / panel-mount frame-1 unit — light enough to handle on a bench without a second pair of hands, but the panel layout still needs to allow airflow above and below the heatsink fins for the drive to hold its rated output without thermal derating.
Where it sits in the ACH580 line
The 07A2-4 frame is the lower-current end of the ACH580-01 wall-mount range; peer ACH580-01-014A-4 sits one frame up at 6.80 kg, with a different heatsink, footprint, and current rating — not a same-frame spare.
