Chassis mass is 34.02 kgs, which puts the unit squarely in wall-mount handling class — the lift is a two-person job and the back panel has to carry the load before the gland plate is even torqued. ## Where the family sits ACS550-U1-143A-2 follows the standard ACS550-U1 wall-mount form factor used across the family, so existing panel cutouts, gland plates, and control-wiring templates from other ACS550-U1 installations carry over mechanically. ## Cross-shop against same-family peers Peer ACS550-U1-072A-4+B055+L512 sits at the same 34.02 kgs chassis weight, so the mechanical envelope and panel reinforcement are a known constant when weighing it as a functional alternative within the ACS550-U1 family. Peer ACS550-U1-059A-4+B055 weighs 36.29 kgs versus this drive at 34.02 kgs; verify panel reinforcement against the heavier chassis before treating it as a drop-in. ## Sourcing posture","metaTitle":"ABB ACS550-U1-143A-2 Motor Drive, 34.02 kgs","metaDescription":"ABB ACS550-U1-143A-2 ACS550 series motor drive, 34.02 kgs.
