The ABB AF140-30-11-11 is an AC non-reversing IEC contactor, 3-pole, rated 130 A, with a 24 VDC coil. The description string "20-6/ABBAF140301111" on the label matches this order code — verify the nameplate against your PO during goods-in to avoid a mix-up with the 110/120 VAC coil variant.
130 A rating and coil voltage
The 130 A rating covers motor loads in AC-3 duty up to roughly 55 kW at 400 VAC — a common size for medium conveyors, pumps, and compressors. The 24 VDC coil keeps control voltage low-voltage, which simplifies panel wiring and avoids running line voltage through pushbuttons or PLC outputs. Coil pickup is typically around 18 VDC; dropout below that threshold. Verify the coil suppression diode polarity if the panel uses a free-wheeling diode across the coil.
Panel integration
The 3-pole power terminals accept cable lugs up to the rated cross-section; the coil terminals are screw-clamp, 2.5 mm² max. Leave clearance above the arc chamber for cooling — the contactor runs warm at full load.
