What it is
The ABB 1SAM250005R1009 is an accessory item in the Contactor & Starter Accessories & Parts class, sitting under the broader Circuit Breakers, Fuses & Protection category tree. It is filed by ABB with the order code 1SAM250005R1009, the same string stamped on the part and used in the title description as '1SAM250005R1009 by ASEA BROWN BOVERI' — the legacy brand string still carried in the listing.
Where the class sits in a panel
Accessories in this class are the bits that finish an ABB motor-starter build — auxiliary blocks, connection modules, and the small parts that mount alongside the main contactor or starter body. They are specified into a BOM to complete a starter assembly, not run as a standalone switching device. For a buyer, that means the order code is keyed to the parent starter series it pairs with; the accessory is useless without the matching ABB contactor/MS family it mounts onto, so confirm the parent series before quoting the line.
