What this line card carries
The ABB 1SBL143061R5110 is filed as an electrical contactor under Contactors and Starters, the kind of part a panel builder drops into a motor-control section to switch a load on and off through its coil. The order code itself — 1SBL143061R5110 — is the identifier the storeroom writes on the bin label and the purchasing clerk types into the PO line; ASEA BROWN BOVERI is the brand string that ships on the nameplate.
