What the order code resolves to
The ABB ACS800-PC-0210-5+B055+L500+L501 is an AC drive from the ACS800 line, ordered with the +B055, +L500 and +L501 option codes built into the string rather than added as separate fieldbus or panel-option line items. Per the spec record, it sits in the Motor Drives class under Motors & Motor Controls, listed at 68.04 kgs — a wall-mount-class chassis that the wireman should plan a two-person lift or a panel-side handling fixture for, not a hand-carry.
Where the ACS800 fits in a panel
Drives in this class are specified between the feeder protection and the motor, taking a fixed AC supply in and delivering a variable-frequency output to the driven machine, with the option codes in the suffix controlling which control interfaces are pre-wired and which braking or line-filter hardware leaves the factory fitted. For panel layout, the 68.04 kg figure is the one to plan around: the unit needs a cleat or back-plate rated for that mass with the centre of gravity kept clear of door-swing interference, and the gland plate below must leave room for the screened motor cable glands the ACS800 series expects at the output side.
Sourcing posture
ABB is the brand of record on this code and the part carries the full option suffix (+B055 +L500 +L501) verbatim, which means a quote-to-order line must match every suffix character — abbreviating to a bare ACS800-PC-0210-5 changes what ships. No production-status entry is on file for this code, so the only honest sourcing posture is to quote it to order against an RFQ; do not assume active or obsolete from the spec record alone. The ledger carries no official successor cross-reference for the ACS800-PC-0210-5+B055+L500+L501, so any swap to an ACS880-01-156A-5, ACS580-01-180A-4 or ACS550-U1-157A-4 has to be engineered against a side-by-side review of frame size, current rating and the option-code mapping — those are real ABB drive families in the same class on file, not confirmed drop-in replacements.
