AF contactors 100A to 370A
AF contactors 100A to 370A are a family of high-performance electromechanical switching devices designed for demanding industrial applications. These contactors feature a robust arc quenching system and are rated for continuous currents from 100A up to 370A, with coil control voltages covering a wide range (e.g., 100-250V AC/DC). They typically ...
AF contactors 100A to 370A are a family of high-performance electromechanical switching devices designed for demanding industrial applications. These contactors feature a robust arc quenching system and are rated for continuous currents from 100A up to 370A, with coil control voltages covering a wide range (e.g., 100-250V AC/DC). They typically offer 3-pole (3P) or 4-pole (4P) configurations, with a rated operational voltage up to 690V AC and a rated insulation voltage of 1000V. The AF technology ensures silent operation and a wide control voltage range, eliminating the need for separate coil voltage selection. They are equipped with electronic coil interfaces that provide immunity to voltage dips and brownouts, making them suitable for unstable power grids. Accessories include mechanical interlocks, auxiliary contact blocks, and surge suppressors.
These contactors are primarily used in motor control centers (MCCs), power distribution panels, and automation systems for switching resistive and inductive loads. They are ideal for controlling three-phase motors, pumps, compressors, conveyors, and HVAC equipment in sectors like water treatment, mining, cement, and manufacturing. Their compact design allows for easy integration into switchboards and control cabinets, while the wide voltage coil simplifies logistics and installation in global projects.
The main subcategories within this range include AF100, AF145, AF205, AF265, and AF370 contactors. For example, the AF100-30-00-13 has a rated current of 100A, 3 poles, and includes a built-in auxiliary contact block. The AF370-30-00-77 handles 370A with 3 poles. The product code structure typically follows: AF[Current rating]-[Number of poles][Number of NO main poles][Number of NC main poles]-[Auxiliary contact configuration]. For instance, AF205-30-11 indicates a 205A, 3-pole contactor with one NO and one NC auxiliary contact.
