What 1SAM250000R1004 actually is
Category placement lists it under Contactor & Starter Accessories & Parts, the class used for accessories that complete an ABB manual motor starter assembly rather than carry the main switching duty.
Class context — where this accessory sits in a panel
ABB manual motor starter accessories of this class are specified into the BOM alongside the starter body to add signalling, tripping or termination functions that the bare starter does not provide on its own. A buyer matching this order code is generally pairing it with a specific MS-series starter frame, so the part number is the contract — not a generic 'fits all starters' claim.
Sourcing posture
No lifecycle status field is carried on this listing, so production state is not asserted here; treat availability as quoted-to-order against an RFQ rather than as a confirmed in-production line.
