AF contactors up to 38 A are compact electromechanical switching devices designed for controlling motors, lighting, and other electrical loads in industrial and commercial installations. These contactors feature a wide control voltage range, typically from 24 to 500 V AC/DC, ensuring stable operation even under voltage fluctuations. They are available in 3-pole (3P) configurations with rated operational currents up to 38 A AC-3, making them suitable for moderate power applications. The AF series includes integrated surge suppressors and electronic coils that reduce power consumption and heat generation. Accessories such as auxiliary contact blocks (e.g., CA4-01, CA4-10), mechanical interlocks (VM4), connecting links (BEA16-4, BEA26-4, BEA38-4), and protective covers (BX4) enhance functionality and safety. These components allow for easy customization, including adding normally open (NO) or normally closed (NC) contacts, and ensuring proper isolation between circuits.
These contactors and their accessories are widely used in motor control centers (MCCs), distribution panels, HVAC systems, pump controls, conveyor belts, and lighting control circuits. They are ideal for applications requiring frequent switching, such as in automation lines, building management systems, and industrial machinery. The compact design facilitates mounting on DIN rails or base plates, saving space in control cabinets. Mechanical interlock units (VM4) enable safe reversing or star-delta starter configurations, while connecting links simplify wiring between manual motor starters and contactors. Auxiliary contact blocks provide feedback signals for PLCs or status indication, making them essential for automated processes.
The AF contactors comply with international standards such as IEC 60947-4-1 and UL 508, ensuring global acceptance and safety. They are compatible with ABB's own range of manual motor starters (e.g., MS116, MS132) and other control devices, but also integrate seamlessly with third-party components from brands like Siemensand Eaton when using appropriate adapters. The electronic coil technology ensures compatibility with various control voltages without needing separate coils, reducing inventory complexity. Accessories like the LDC4 additional coil terminal block and CAT4 auxiliary contact/coil terminal blocks maintain signal integrity and simplify installation.
