Series AF 3-pole Contactors
The AF2050-30-11-70 is a 3 pole - 1000 V IEC or 1000 V UL contactor with pre-mounted auxiliary contacts and Main Circuit Bars, switching power circuits up to 2050 A (AC-1) or 2100 A UL general use. Thanks to the AF technology, the contactor has a wide control voltage range (100-250 V 50/60 Hz and DC), managing large control voltage variations, reducing panel energy consumptions and ensuring distinct operations in unstable networks. Furthermore, surge protection is built-in, offering a compact solution. AF contactors have a block type design, can be easily extended with add-on auxiliary contact blocks and an additional wide range of accessories.
AF 3-pole Contactors
ABB's AF series includes a variety of 3-pole contactors designed for controlling 3-phase motors and power circuits. These contactors are categorized into several sub-series based on their current ratings and applications.
Each sub-series features integrated electronic coils that reduce energy consumption by up to 80%, provide surge protection, and allow operation across wide voltage ranges without coil changes. ABB also offers auxiliary contact blocks and accessories to enhance functionality
