The 2 in 088A-2 puts the unit in the 2xx voltage class rather than the 4xx class — the line voltage on the nameplate has to match the BOM call-out before it lands on a panel. Listed at 31.75 kgs, it is a two-person lift and a cabinet-mount drive, not a wall bracket. ## What +B055 and +L512 actually buy you ABB encodes the option set into the order code itself, so the suffix string is part of the part number, not a field-configured add-on. The base drive is the ACS550-U1-088A-2; +B055 and +L512 ship fitted, which means a swap-in unit must carry both codes verbatim or the control terminals, I/O map, or option-card stack will not match what the integrator originally commissioned. ## Cabinet handling At 31.75 kgs, the drive wants a proper cabinet chassis or backplate, not a hang-on-the-wall bracket — factor lifting clearance above the mounting surface and use the integral lifting eye rather than gripping the heat sink fins.","metaTitle":"ABB ACS550-U1-088A-2+B055+L512 Motor Drive, 31.75 kgs","metaDescription":"ABB ACS550-U1-088A-2+B055+L512 ACS550 series motor drive in the 2xx voltage class with +B055 and +L512 option codes.
