What the line carries
The 1SAM150000R1001: As a class, ABB contactor and starter accessories and parts are the auxiliary and replacement items that hang off a motor-starter assembly — busbars, link modules, terminal shields, and the like — so a buyer hitting this order code is typically refilling a single BOM slot rather than specifying a whole starter.
Sourcing posture
No explicit lifecycle or production-status entry is on file for 1SAM150000R1001, so the line is sourced to order against an RFQ rather than called active or obsolete — submit the part number with quantity and the request is quoted back through the available channel.
