What lands when you punch in this code
The ABB ACS355-03E-15A6-4 is the 7.5 kW rating slot of the ACS355 machinery-drive family — 15.6 A output on a 3-phase 380-480 V supply, R3 frame in IP20, with the '03E' suffix telling you it ships as a 3-phase unit with the internal EMC filter connected and 50 Hz mains wiring. The 15A6 in the order code is ABB's rating code for 15.6 A nominal, matching the title-line figure of 7.5 kW at 400 V ac — so when the BOM calls for the 7.5 kW / 15.6 A slot of the ACS355 line, this is the suffix that fills it.
Reading the envelope — what each rating actually governs
The '03E' construction is a 3-phase input with the EMC filter connected from the factory, which matters for cabinet CE conformity: leave the filter in circuit for industrial installations, and remember the filter is what carries the typical earth-leakage budget — site grounding and RCD selection both hang off that choice. At 3.3 kg unit weight and an R3 IP20 footprint, it wall-mounts inside the cabinet on the standard ACS355 pattern; the 4.5 kg shipping weight is the carton figure and not a panel-loading number.
Sourcing posture
ACS355-03E-15A6-4 is a current ABB machinery-drive order code — the title, rating, and frame data match the live family. Standard industrial-distributor channel ships in 1-10 working days from order; quote it on the RFQ against the MPN and the 15.6 A / 7.5 kW slot.
