ABB AF400B-30-22-71 Block Contactor - 1000 V IEC
Part Number: 1SFL577063R7122
Quick Summary
ABB AF400B-30-22-71 is a 3-pole contactor for motor control up to 200 kW at 400 V AC. In demanding panels, wide control voltage variation can cause nuisance trips and energy waste; AF technology mitigates this by tolerating 250–500 V AC, plus DC, with built‑in surge protection. The device carries CE and UL/cULus approvals along with several additional certificates, enabling global deployment. Its compact block design, pre-mounted auxiliary contacts, and easy expansion with add-on contact blocks deliver scalable control for factory automation. This combination provides reliable motor switching, simplified installation, and lower maintenance costs in industrial applications such as conveyors, pumps, and fans.
Product Information
Extended Description
1SFL577063R7122 ABB: The AF400B-30-22-71 is a 3 pole - 1000 V IEC or 600 V UL contactor with pre-mounted auxiliary contacts and standard ferrules, controlling motors up to 200 kW / 400 V AC (AC-3) or 350 hp / 480 V UL and switching power circuits up to 600 A (AC-1) or 550 A UL general use. Thanks to the AF technology, the contactor has a wide control voltage range (250-500 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.
