The listing header carries the legacy corporate string ASEA BROWN BOVERI rather than ABB; sourcing systems that still index the older name will still resolve the same order code. ## Reading the suffix for panel fit The -U1- body marks the standard wall-mount drive enclosure used across the ACS550 family, and the +B055 plus-code is the order-level option that has to be carried forward verbatim whenever this drive is specified as a BOM line or re-ordered as a spare. At 9.98 kg the unit sits in the range that a single technician can lift onto a mounting plate, but the cabinet layout still needs to allow clearance for the heatsink airflow path; treat the mass as a handling input for the install plan, not a selection criterion. ## Same-family peers worth knowing Within the ACS550-U1 wall-mount family, ACS550-U1-096A-4 is a higher-current frame at 19.96 kg, ACS550-U1-072A-4+B055+L512 is an option-loaded build at 34.02 kg, and ACH550-UH-023A-4 is the HVAC-flavored ACH550 sibling at 11.34 kg.","metaTitle":"ABB ACS550-U1-023A-4+B055 AC Drive, 9.98 kg","metaDescription":"ABB ACS550-U1-023A-4+B055 AC drive on the Motor Drives line, 9.98 kg.
