Class role in the starter assembly
Accessories in this category typically complete the protection and control stack on a manual motor starter or contactor block — busbars, link modules, terminal shrouds, and auxiliary blocks — so the part number on the BOM is usually the matching variant code for the host starter frame, not a free-standing component. The 1SAM series part number is the ABB-coded accessory matched to the host manual motor starter or contactor family, not a free-standing component.
