The line above it in the category tree places it under Drives / Motor Drives, which is where a panel-builder will look for it when sizing the motor-control column. ## Rating class and what it implies At 408.23 kgs, treat the rigging and the mounting plinth as part of the BOM. A drive this heavy isn't a swap-in replacement; the panel footprint and the cable bend radii are part of the spec, not an afterthought.","metaTitle":"ABB ACS550-U2-526A-4, 526A 400V drive","metaDescription":"ABB ACS550-U2-526A-4 ACS550 series 526 A drive, listed at 408.23 kgs.
