What it is and where it sits in the panel
The ABB ACS580-01-145A-4 is a 145 A frame frequency converter from the ACS580-01 series, built for 3-phase 380... 480 V supplies at 50/60 Hz and rated for wall-mounting with an IP21 enclosure. On the control side the package carries 2 analog inputs and 2 analog outputs, which is the typical complement for a general-purpose industrial drive handling speed reference and process feedback loops without needing an expansion I/O card. The mechanical envelope is 36.9 cm x 25.2 cm x 72.7 cm and the unit weighs 42.4 Kg (44 Kg shipping), so the wall it's fixed to and the lifting plan both need to account for that mass at install time.
What the ratings actually govern
The 380... 480 V input window covers the spec's listed supply range across 50/60 Hz three-phase, and the same order code fits either panel voltage on record. IP21 is a drip-proof indoor rating, not a washdown or outdoor enclosure — if this drive is going anywhere near a wet process, hose-down area, or an outdoor cabinet, the IP21 chassis is the wrong fit and the panel envelope has to take the environmental hit, not the drive itself. The 2 AI / 2 AO count is what the integrator is going to plan the wiring against: one reference, one feedback is the typical split, with the two analog outputs free for indication or a secondary process variable if the application calls for it.
Sourcing posture
Production-status entry is not on the record for this order code, so anything about active manufacture versus obsolescence is left off the page — what is solid is that it carries the standard ABB ACS580-01 datasheet footprint, with a quoted lead-time window of 1-10 working days when specified into a BOM. For buyers specifying into a BOM, send the order code, panel voltage, motor rating, and I/O map on the RFQ; supply runs through the standard ABB ACS580-01 distributor channel and pricing confirms against the actual quote.
