Part Number: 1SFL637063R7122
Quick Summary
AF750B-30-22-71 Contactor is a high-capacity switch designed for motor control applications in industrial automation. In practice, fluctuating control voltages can lead to nuisance tripping or delayed pull-in; this model's broad 250–500 V AC/DC control range mitigates those issues. Key certifications include CE conformity, UL/cUL recognition, and RoHS/REACH compliance, providing confidence across global supply chains. For businesses, this translates to lower maintenance, easier commissioning, and compatibility with add-on auxiliary blocks. The AF750B series supports pre-mounted auxiliary contacts, standard ferrules, and a block-type design that scales with your automation needs, reducing panel space and assembly time.
Product Information
Extended Description
1SFL637063R7122 ABB: The AF750B-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 400 kW / 400 V AC (AC-3) or 600 hp / 480 V UL and switching power circuits up to 1050 A (AC-1) or 900 A UL general use.

FAQs
For reliable performance, mount the unit as specified, connect main circuits to bars (52 mm²) or rigid Cu/Al cables up to 300 mm², and torque cable lugs to 45 N·m. Use the pre-mounted auxiliary contacts and ferrules to simplify wiring, and ensure the ambient temperature ranges are respected: −25 to 50 °C near the relay, or −40 to 70 °C without. This reduces mis-operation and extends life in harsh environments.
The AF750B offers a wide coil voltage range of 250–500 V (AC, 50/60 Hz) and DC, ensuring stable pull-in and holding even when supply voltage fluctuates. Coil consumption is rated at 12 VA holding and 910 VA at pull-in, enabling robust operation in networks with transients and fluctuations, which lowers nuisance trips and improves process uptime.
Yes. The 3-pole AF750B can switch motors up to 400 kW at 400 V AC (AC-3) and handle up to 1050 A for AC-1 applications. It is rated for up to 1000 V IEC in main circuits and 600 V UL in UL configurations, making it suitable for demanding production lines, conveyors, pumps and other heavy-duty loads.
This contactor ships with CE declaration of conformity and UL/cUL recognition. It also references RoHS and REACH compliance, along with environmental declarations (EPD) and related certifications. The wide certification coverage supports global procurement and regulatory alignment across manufacturing and industrial facilities.
The AF750B reduces lifecycle costs through lower energy consumption in the control circuit, built-in surge protection, and a scalable design with add-on auxiliary blocks. Its robust construction minimizes maintenance, improves uptime for critical loads, and simplifies future expansions, delivering a favorable total cost of ownership in demanding automation environments.
