What the line is
The ABB ACS800-U4-0210-5-D150-L503 is a wall-mount industrial AC drive from the ACS800 family, listed under Motors & Motor Controls › Drives › Motor Drives and built around the legacy U4 cabinet form factor. The unit registers at 100.24 kg, which puts it firmly in two-person-lift territory and ahead of the current-generation ABB wall-mount drives on mass — factor that into cabinet sizing and door-hinge ratings before specifying.
Frame delta vs current-generation wall-mounts
The ACS880-01-156A-5 is listed at 55.00 kgs versus the ACS800-U4-0210-5-D150-L503 at 100.24 kg, so the ACS880 is a different mechanical package rather than a like-for-like panel swap. The ABB ACS580-01-180A-4 lands at 54.43 kgs, again well under the ACS800's 100.24 kg — same conclusion: same drive class, different frame generation, and panel re-fit is a real exercise.
Sourcing posture
For an MRO spare on a running ACS800 line, specify the full option string when ordering — the trailing -D150-L503 suffix is part of how the cabinet, filter stack and option cards are configured, and a near-match suffix lands the wrong gate-drive or EMC filter on the bench.
