ABB 1SFL607263R1222 Contactor - UL/CSA 520A
Part Number: 1SFL607263R1222
Quick Summary
AF370B Contactor is a four-pole motor controller designed for AC-3 motor control in industrial panels. Wide control voltage tolerance helps prevent nuisance tripping and reduces panel energy waste amid fluctuating networks. CE and UL/CSA approvals, RoHS and REACH compliance ensure safe operation, recognized quality, and regulatory alignment across regional builds. The device ships with pre-mounted auxiliary contacts and ferrules, and its block-type design supports quick expansion with add-on contact blocks, minimizing panel rework. For OEMs and machine builders, this translates to shorter wiring runs, easier service, and lower total cost of ownership. The AF technology delivers stable performance even in voltage-varied or harsh environments, boosting overall reliability of motor-driven lines.
Product Information
Extended Description
1SFL607263R1222 ABB: The AF370B-40-22-12 is a 4 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) / 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 (48-130 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.
