The ABB AF09-40-00-14 (Part Number 1SBL137201R1400) is a compact and dependable 4-pole contactor engineered for switching motors and power circuits in industrial control panels, machinery, HVAC systems and building automation. As part of the advanced ABB AF contactor series, it features innovative electronic coil technology that accepts an exceptionally wide control voltage range, helping simplify panel design while improving operational reliability.
ABB AF contactors are designed to tolerate voltage dips and fluctuations without nuisance tripping. The integrated electronic AC/DC coil eliminates the need to stock multiple coil variants, whilst built-in surge suppression reduces installation complexity and enhances long-term performance in demanding industrial environments.
With an AC-3 operational current of 9 A, an AC-1 rating of 25 A and a 250-500 V AC/DC electronic control coil, the AF09-40-00-14 is ideal for controlling motors, heating circuits, lighting and other industrial loads. Its compact DIN rail or panel mounting format makes installation straightforward inside electrical control cabinets.
Industrial contactors provide safe and efficient switching of electrical loads by allowing low-power control circuits to operate higher-power equipment. ABB AF contactors combine electronic coil technology with compact construction to improve system reliability while reducing energy consumption and simplifying inventory management.
The AF09-40-00-14 is widely used by panel builders, machine manufacturers and maintenance engineers requiring dependable switching performance across varying control voltages and demanding industrial environments.
