The ABB AF38-40-00-14 (Part Number 1SBL297201R1400) is a premium 4-pole contactor designed for switching power circuits in industrial machinery, HVAC systems, process automation and OEM control panels. As part of the advanced ABB AF contactor series, it incorporates ABB's innovative electronic coil technology, delivering dependable switching performance across a wide control voltage range whilst simplifying machine design and reducing spare parts inventory.
ABB AF contactors are engineered to tolerate voltage dips and fluctuations without nuisance tripping. Their integrated electronic AC/DC coil allows a single contactor to operate across multiple worldwide control voltages, whilst built-in surge suppression removes the need for external suppression devices. This results in a more compact, reliable and energy-efficient installation.
With an AC-3 operational current of 22 A at 400 V AC, an AC-1 operational current of 55 A and a 250-500 V AC/DC electronic control coil, the AF38-40-00-14 is ideal for controlling three-phase motors, heating circuits, lighting and resistive loads. Its compact DIN rail or panel mounting design enables straightforward installation inside industrial electrical cabinets.
Industrial contactors enable low-power control circuits to safely switch higher-power motors and electrical loads. The ABB AF38-40-00-14 combines advanced electronic coil technology with robust construction to deliver dependable switching performance, reduced energy consumption and reliable operation even where supply voltages fluctuate.
Its wide electronic control voltage range makes it particularly suitable for OEMs, machine builders and panel manufacturers supplying equipment globally, reducing inventory whilst improving application flexibility.
