The ABB 3BBR0000161801 is an ACS880-04-370A-7 drive module in Frame Size R10. This is the power stage of a modular multidrive cabinet build — the section that handles the 370 A output to the motor. Frame R10 defines the mechanical footprint, busbar layout, and cooling duct interface for the cabinet integration.
Verify the cabinet's air-flow path and busbar kit match the R10 interface.
