What it is
The ABB 1SAM150000R1011 is the manual accessory line card entry under the contactor and starter accessory rail — sitting one tier below circuit breakers, fuses and protection, and one tier above the contactor and starter accessories and parts subcategory. The listing titles it as a manual by ASEA BROWN BOVERI, so on a BOM it reads as the human-machine interface or operator accessory that pairs with the contactor/starter assembly rather than the contactor itself.
