The ABB 3BBR0000182370 is a drive module from the ACS880-04XT family, designated ACS880-04XT-1320A-7, built in frame size 2xR11. This is the physical chassis that houses the power stage and control electronics for a high-current AC drive — the frame size tells you the mechanical footprint, busbar layout, and cooling duct interface. If you are replacing a failed unit or building a panel from a BOM that calls out this order code, the 2xR11 frame is the dimension you match against the cabinet cutout and buswork.
What the Frame Size Tells You
Frame size 2xR11 is a dual-module configuration — two R11 power stages paralleled inside a single mechanical assembly. This is typical for drives above roughly 600–800 A output, where a single R11 frame would hit its thermal or busbar limit. The 2x prefix means the cabinet designer needs to account for the combined width (two R11 footprints side by side) and the shared DC bus connection. If your existing drive is a single R11 and you are upgrading current capacity, verify that the cabinet has the extra width and that the incoming DC bus bars can feed two parallel sections.
