The ABB ACS880-M04-094A-5 is a module in the ACS880 industrial drives family, specified for a 3~ 380-500 V supply window, with a listed mass of 21.32 kgs. The 3~ 380-500 V supply window covers the standard European and North American three-phase feeds on retrofit and new-line work. At 21.32 kgs the unit is a two-person lift and the cabinet or cubicle that carries it has to be rated for that mass at the intended mounting height — not a desk-side drop-in.
Where this part sits in the ACS880 family
The ACS880-M04-094A-5 carries the -M04 suffix that marks ABB's multi-drive (common-DC-bus) configuration, where the inverter modules share a supply rectifier and DC link rather than each having its own input section.
