The device carries CE, UL/CSA General Use, and UKCA declarations, along with RoHS and REACH compliance, ensuring global market access. By combining a compact footprint with pre-mounted auxiliary contacts and a broad accessory ecosystem, it reduces wiring complexity, installation time, and total cost of ownership, while meeting stringent safety and performance standards for modern factories.
Product Information
Extended Description
1SFL607263R1422 ABB: The AF370B-40-22-14 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 (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.

Four-pole construction enables robust motor switching, with a main circuit rated to 1000 V and AC-1 current up to 400 A; AC-3 rating reaches 370 A. This translates to a compact, space-saving panel design and clear load separation for demanding conveyors and pumps. Practical application: directly replaces multiple smaller devices and simplifies fault tracing. The coil control range of 250–500 V AC or DC, plus built-in surge protection, tolerates supply variations and reduces nuisance trips, delivering more stable operation and energy efficiency in fluctuating networks. Pre-mounted auxiliary contacts (2 NO and 2 NC) simplify control logic and wiring, with add-on blocks available for scalable automation and safer interlocks in complex start/stop sequences. AF technology also contributes to improved energy management, reducing heat and panel cooling needs while maintaining reliable switching at high duty cycles. Dimensional data (184 mm width, 180 mm depth, 225 mm height) and a 5.7 kg weight support straightforward installation in standard enclosures, with compatibility for CAD data and accessory blocks to accelerate engineering workflows.

FAQs
Begin with confirming a four-pole main circuit and existing support for 1000 V operation. Connect the main circuit bars as specified, mount the device in a suitable enclosure, and attach the pre-mounted auxiliary contacts (2 NO, 2 NC). Ensure wiring conforms to local standards and that the coil voltage matches the control supply (250–500 V AC/DC). Use the CAD data for layout, verify clearances, and incorporate add-on auxiliary blocks if zoned control requires extended signaling. Finally, perform a functional test and verify coordination with protective relays to prevent nuisance trips.
Key ratings include the main circuit voltage up to 1000 V, AC-1 current up to 400 A (1000 V, 40 °C), and AC-3 current up to 370 A at 415–440 V. The coil operates at 250–500 V for both AC and DC control, with built-in surge protection. The unit provides four poles (4P) and includes 2 NO/2 NC auxiliary contacts, which supports common motor start/stop circuits and interlock schemes. Ensure compliance with CE, UL/CSA, and UKCA for your region.
This contactor is ideal for motor protection and control in manufacturing lines, conveyors, pumps, and machine tools where reliable switching of high-current loads is required. Its 4P configuration and 1000 V rating support high-power motors up to about 200 kW (AC-3) across diverse voltages. The wide coil voltage tolerance reduces tripping in unstable networks, while the pre-mounted auxiliary contacts simplify control circuits and interlocks in start/stop sequences.
The AF370B-40-22-14 carries CE, UL/CSA general use ratings, and UKCA declarations. It also complies with RoHS and REACH, and is supported by related certificates such as UL Certificates and CQC/CCC in relevant markets. Environmental declarations include EPD for AF(S)265–AF(S)370 series and information on recyclability and end-of-life instructions, supporting responsible procurement and regulatory adherence.
The 4P AF370B-40-22-14 reduces panel footprint and wiring complexity, cutting installation time and cabling costs. Built-in surge protection and wide voltage tolerance minimize nuisance trips, improving line uptime. Its mechanical durability (millions of cycles) supports longer service intervals, and the ability to add auxiliary blocks enables scalable control logic without significant rewiring. Overall, it lowers lifecycle costs while boosting energy efficiency in motor control.
