What the order code identifies
The ABB ACS800-U4-0270-5+E210+P901 is a cabinet-format AC drive from the ACS800-U4 line, configured with the +E210 and +P901 option codes and listed as an AC cabinet drive by ABB.
Handling and mounting consequence
At 199.58 kg this is a floor-standing enclosure, not a wall-mount unit — rigging, fork-truck placement, and floor load are real engineering considerations before it lands on the shop floor.
Sourcing posture
Second-source question — ACS880-01-156A-5 is not a drop-in
The ACS550-U1-157A-4 at 89.81 kg is another wall-mount generation older than the ACS880 line, and the ACS880-01-065A-5 at 23.13 kg is a smaller-frame ACS880 unit — none of these are mechanical or ratings peers for a 199.58 kg ACS800-U4 cabinet, so a true cross-reference has to come from the official ABB migration matrix, not from parametric adjacency.
