It is a wall-/cabinet-mount inverter, not a soft starter, and not a contactor. Chassis mass is 10.35 kgs — a meaningful handling item for a one-person lift and a panel-rated mount, not a shelf component. Plan the backplate fixing and the person carrying it before the unit is opened. ## Where this class gets used ACS550-01 inverters are the general-purpose industrial drive in ABB's legacy catalogue. The class typically runs fans, pumps, conveyors and similar variable-torque or constant-torque loads where the inverter replaces across-the-line starters and needs the standard ABB parameter set plus a fieldbus option for the panel's PLC. ## Same function, different family — read the suffix The ACS880-01-027A-5 at 10.41 kgs is the closest ACS-platform sibling — modern ABB platform, similar chassis mass. If a panel-footprint or mounting-depth check passes, the ACS880 is a second-source direction; if it doesn't, the BOM line still needs an RFQ against this exact code.","metaTitle":"ABB ACS550-01-044A-4 Drive Inverter, 10.35 kg","metaDescription":"ABB ACS550-01-044A-4 drive inverter on the Motor Drives line at 10.35 kgs.
