What this drive is on the BOM
The ABB ACS850-04-260A-5+J400 is the cabinet-class wall-mount form of the ACS850 industrial drive family, and the +J400 suffix is a factory option code applied at order time so the same base part number covers several pre-configured variants in the field. Mass is listed at 66.68 kgs, which puts it firmly above the one-person lift ceiling; a two-person lift, an adequately rated cabinet floor or wall bracket, and the correct fork-truck or hoist point at unpacking are the practical handling constraints a sourcing planner should already be putting on the work order.
Frame-class context inside the ABB ACS family
For a buyer weighing the ACS850-04-260A-5+J400 against a newer platform, the ACS880-01-156A-5 sits in the cabinet-class successor family at a different frame size and a markedly lower mass of 55.00 kgs, so a like-for-like panel swap is a frame decision first and an electrical-rating decision second — not a connector-by-connector drop-in. The ACS580-01-180A-4 lands lower in the family hierarchy at 54.43 kgs and is the general-purpose successor a controls integrator usually reaches for on a green-field retrofit, while the ACS550-U1-157A-4 at 89.81 kgs is the legacy mid-frame a storeroom may still be holding spares for — three ABB drives a buyer may already have on the shelf, but none of them a guaranteed cross for this specific ACS850-04 order code.
Storeroom posture and sourcing reality
From the MRO-storeroom angle, the ACS850-04-260A-5+J400 is an ABB cabinet drive with a defined +J400 option string, so it does not consolidate down to a generic 'ACS850 spare' on the shelf — every variant in this series carries its own option code and that is exactly the kind of one-off special that sits dead if it is not tied to a known running unit.
What an integrator actually asks before signing the BOM
Before the controls integrator signs the BOM line they need the matching control panel, the fieldbus option slot assignment, and the brake-chopper / line-filter configuration called out against the +J400 suffix — items the spec table on this listing does not carry, so they belong in the RFQ reply rather than in any assumption at PO time.
