What you're looking at
Order code 1SAM350000R1014 is the exact string to put on the BOM line.
Where it lives in a panel
On a motor-starter assembly the MCCB is the short-circuit and isolation device upstream of the contactor, so the 1SAM350000R1014 takes the fault let-through and lets the contactor handle the normal switching duty. That split — breaker for fault isolation, contactor for operational cycling — is why motor-protection MCCBs are spec'd differently from feeder MCCBs on the same bus.
Sourcing posture
No production-status assertion is made here; supply is handled through the quote-and-confirm path.
