What it is and where it sits
The ABB 1SBL136061R2101 is an electrical contactor from the AF-line contactor family, ordered against a wide-range coil that accepts 24-60 VAC at 50/60 Hz or 20-60 VDC on the same terminals — useful where the panel feed is uncertain or where a single BOM line has to cover both AC control supply and a DC battery-backed rail. It falls in the Electrical Contactors slice of the Contactors and Starters class (Circuit Breakers, Fuses & Protection › Contactors and Starters › Electrical Contactors), which is the standard home for DIN-rail mount switching devices sized for motor and resistive loads.
Sourcing posture
ABB is the listed brand. No production-status field is present, so lifecycle is not asserted. Quote against an RFQ for the BOM line and specify it like any other AF-line contactor on the panel drawing.
