What the line item is
The ABB 1SBL141001R8510 is catalogued as an electrical contactor under the broader Contactors and Starters group, sitting inside the Circuit Breakers, Fuses & Protection top-level category. The listing title and description both name it plainly as a CONTACTOR by ASEA BROWN BOVERI, and the part identifier on the line is 1SBL141001R8510 — that's the string that goes on the purchase order and on the nameplate cross-check at goods-in.
