The ABB AF370-40-11-14 (Part Number: 1SFL607102R1411) is a heavy-duty 4-pole industrial contactor designed for switching high-current power circuits and controlling three-phase motors in demanding industrial applications. As part of the proven ABB AF contactor series, it features advanced electronic coil technology that delivers dependable performance across a wide control voltage range while improving energy efficiency and reliability.
The integrated AF electronic coil accepts a 250-500 V AC/DC control voltage, allowing the contactor to operate reliably during voltage fluctuations and unstable network conditions. Built-in surge suppression eliminates the need for external suppression devices while reducing panel complexity and improving long-term system reliability.
With a 525 A AC-1 switching capacity and the ability to control motors up to 200 kW at 400 V AC (AC-3), the AF370-40-11-14 is ideal for industrial machinery, motor control centres, HVAC equipment and electrical distribution systems where dependable switching performance is essential.
The ABB AF370-40-11-14 is engineered for reliable switching of motors and high-current electrical loads. Its electronic AF coil technology maintains consistent operation despite voltage dips and fluctuations, helping maximise uptime while reducing coil energy consumption and simplifying panel design.
The block-type construction allows easy expansion with auxiliary contact blocks and additional ABB accessories, making the contactor suitable for modern industrial automation systems, OEM machinery and electrical distribution equipment.
