The ABB 1SBL136201R2100 is a 4-pole AF Series contactor with a 24 V ac/dc coil, rated 7 A and 4 kW at 690 V ac, configured 4 normally open (4NO) main poles. The 24 V universal coil accepts both AC and DC control voltage without needing a separate rectifier or coil-change for different supply types — one part covers both, which simplifies panel wiring and spares stocking on mixed-voltage control circuits.
Snap-on DIN rail mounting per EN 60715. The 4-pole, 7 A frame fits standard 45 mm wide contactor footprints; the 24 V ac/dc coil draws minimal VA/W from the control transformer, leaving headroom for additional pilot devices on the same 24 V bus.
