Designed to connect with the AF contactors family, it enables scalable motor protection and reduced maintenance. The AF technology delivers a wide control voltage range and built-in surge protection for stable operation in challenging networks. This combination supports efficient, reliable drives in manufacturing and process automation while simplifying panel design. Realized energy savings and improved uptime translate to lower total cost of ownership.
Product Information
Extended Description
1SFL607262R1422 ABB: The AF370B-40-22RT-14 is a 4 pole - 1000 V IEC or 600 V UL contactor with pre-mounted auxiliary contacts and ring tongue ferrules, controlling motors up to 200 kW / 400 V AC (AC-3) / and switching power circuits up to 525 A (AC-1) or 420 A UL general use. Thanks to the AF technology, the contactor has a wide control voltage range (250-500 V 50/60 Hz ), 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.

FAQs
Install the four main contacts and two auxiliary contacts using the provided ring tongue ferrules for secure connections. The unit uses bar-type main terminals and supports easy expansion with add-on auxiliary blocks. Plan wiring to minimize cross-talk and ensure adequate clearance for safe maintenance in standard motor control panels.
AC-1 ratings include up to 400 A at 1000 V (60°C) and up to 525 A at 690 V (AC-1). AC-3 ratings are 370 A at 415-690 V. This allows the AF370B-40-22RT-14 to drive motors up to around 200 kW in typical industrial drives while meeting UL/CSA requirements.
Yes. The AF370B-40-22RT-14 is designed for AC-3 motor loads with high switching capability and a main circuit rated up to 1000 V. It balances motor control efficiency with robust protection and is compatible with 690 V systems commonly used in heavy industry.
The device carries CE Declarations of Conformity, UL/CSA approvals, UKCA declarations, and RoHS REACH compliance. It also supports cURus and CCC certifications, ensuring regulatory compliance for global installations and safe operation in diverse markets.
Expect longer intervals between maintenance thanks to a mechanical durability spec of around 5 million cycles and built-in surge protection that reduces arc-events. The wide control voltage range lowers energy waste, while modular add-on contacts simplify expansion, improving uptime and lowering total cost of ownership over the asset lifecycle.
