The ABB 1SAM150000R0011 is filed on the Contactor and Starter Accessories and Parts line under Circuit Breakers, Fuses & Protection, sitting in the wider Contactors and Starters class as an accessory or replacement item rather than a stand-alone contactor or breaker.
Where the class is used
Accessories on this class slot into ABB's contactor and motor-starter builds — typically as link modules, terminal shrouds, or wiring kits that bridge the breaker half and the contactor half of a manual motor starter or a coordinated starter assembly.
Sourcing posture
No production-status, last-time-buy, or successor designation is on file for the ABB 1SAM150000R0011 in this ledger, so the supply channel is best handled as a quoted-to-order line: drop the MPN on an RFQ with the panel BOM line context and let the desk come back with the current lead path.
