AF contactors to 38 A represent a critical component in modern industrial automation and motor control systems. These electromechanical switching devices are designed for reliable operation in demanding environments, featuring coil voltages from 24 VDC to 500 VAC, with integrated electronic coil interfaces that eliminate the need for separate surge suppressors. The AF series offers a wide control voltage range, typically from 20% to 80% of the rated coil voltage, ensuring stable pick-up and drop-out characteristics. With rated operational currents up to 38 A in AC-3 utilization category (motor starting), these contactors handle three-phase motors up to 18.5 kW at 400 VAC. They are available in 3-pole (3P) configurations, with optional 4-pole (4P) variants for specific applications. The compact design allows for easy mounting on DIN rails or base plates, and they support a range of accessories including mechanical interlocks, auxiliary contact blocks (1 NO + 1 NC or 2 NO + 2 NC), and thermal overload relays for comprehensive motor protection.
These contactors are primarily deployed in motor control centers (MCCs), distribution panels, and automation cabinets across various industrial sectors. Common applications include controlling conveyor systems, pumps, compressors, fans, and HVAC equipment in manufacturing plants, water treatment facilities, and building management systems. They are also integral to machine tools, packaging machinery, and material handling equipment where frequent switching and high inrush currents are typical. The AF technology ensures silent operation and reduced power consumption in holding mode, making them suitable for energy-efficient installations. Additionally, they are used in lighting control circuits and resistive loads such as heaters in industrial ovens.
Within the AF contactor category up to 38 A, key subcategories include the AF09, AF12, AF16, AF26, and AF38 series, each corresponding to specific current ratings. For example, the AF09 series covers contactors rated at 9 A in AC-3, while the AF38 handles 38 A. The article codes typically follow a pattern like AF09-30-00-11, where 'AF09' indicates the series and current rating, '30' denotes 3 poles, '00' represents the standard coil voltage code, and '11' specifies the auxiliary contact configuration (1 NO + 1 NC). Other common codes include AF12-30-00-11, AF16-30-00-11, AF26-30-00-11, and AF38-30-00-11. These contactors are often paired with thermal overload relays such as the TA25DU series for motor protection.
