Contacteurs AC large tension de la série AF ABB, de AF09 à AF1250

Les contacteurs de la série AF d’ABB utilisent une technologie innovante de bobine de commande électronique, nécessitant seulement quatre types de bobines pour couvrir une large plage de tension allant de 24V AC et 20V DC à 500V AC/DC. Cela permet la compatibilité AC/DC, réduisant significativement les modèles de produits de 90 % et simplifiant efficacement la sélection et la gestion des stocks. Sa conception à large tension peut gérer les fluctuations de tension à travers différents réseaux électriques mondiaux, assurant un fonctionnement continu même lors des chutes de tension. De plus, cette série intègre un parasurtension intégré, éliminant ainsi le besoin d’accessoires supplémentaires et réduisant la complexité de conception. Il réduit également la consommation d’énergie des bobines de 80 %, le rendant plus économe en énergie et écologique, et permet diverses méthodes de câblage telles que des vis et des ressorts pour une installation pratique et rapide.

Key Features Explained

As can be seen from the parameters above, the AF series has the following significant characteristics:

● Wide Voltage, AC/DC Universal Coil: This is the core advantage of the AF series. A single contactor can cover a wide voltage range (e.g., 100-250V AC/DC), suitable for different global power grid standards. There is no need to replace the coil for different control voltages, significantly simplifying selection and inventory management.

● Strong Resistance to Voltage Fluctuations: The electronic coil can withstand short-term voltage drops and interruptions, ensuring continuous operation of the equipment when the power grid is unstable. It complies with SEMI F47 standards and is particularly suitable for applications with strict power quality requirements.

● Integrated Surge Suppressor: A surge suppressor is integrated inside the coil, eliminating the need for additional purchase and installation, simplifying design and saving cabinet space.

● "Mirror Image Contacts" and Safety: Some models have built-in NC auxiliary contacts that are "mirror image contacts," compliant with IEC 60947-4-1 standards. This provides enhanced safety diagnostic capabilities, especially suitable for safety circuits requiring high reliability. Large 4-pole contactors can also be equipped with auxiliary contact blocks featuring mirror image contacts.

● Strong Wiring Capabilities: The main circuit wiring capabilities vary significantly between different models, ranging from small-gauge AWG 16-10 wires to large-gauge cables capable of connecting up to 4/0 AWG (approximately 120mm²) and even 500 MCM (approximately 240mm²), meeting the diverse needs of everything from small-power motors to large-scale power distribution systems.

Key Features Explained:

ABB contactor model naming contains crucial information; understanding this can help you quickly identify the product you need. For example, consider model AF50-30-11-13:

● AF50: Series and frame current (50A).

● 30: Indicates 3-pole (3 Pole) normally open main contacts.

● 11: Indicates auxiliary contacts are 1 normally open (1NO) + 1 normally closed (1NC).

● 13: Coil voltage code, corresponding to 100...250V AC/DC.

● Note: The correspondence between the coil voltage code and the voltage range is crucial for model selection. For example, code -11 typically corresponds to 24...60V AC / 20...60V DC, while -13 corresponds to 100...250V AC/DC, and -14 corresponds to 250...500V AC/DC.
