Product Information
Extended Description
1SFL587102R1211 ABB: The AF305-40-11-12 is a 4 pole - 1000 V IEC or 600 V UL contactor with pre-mounted auxiliary contacts and Main Circuit Bars, controlling motors up to 160 kW / 400 V AC (AC-3) / and switching power circuits up to 500 A (AC-1) or 350 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.

FAQs
This block contactor supports flexible main circuit connections using 2 x 70–185 mm² flexible cables or rigid Al/Cu options up to 240 mm² for main circuits, plus flexible 2x0.75–2.5 mm² or solid 2x1–4 mm² for auxiliary circuits. Main terminals are designed for Bar connections with IP00 protection, while coil terminals are IP20, enabling straightforward, reliable panel wiring and secure terminations.
For AC-3 operation at 415–440 V, the device provides up to 305 A with a rated motor output of about 160 kW at 415–440 V. In AC-1 configuration, ratings vary by ambient temperature: 375 A at 40 °C, 325 A at 60 °C, and 260 A at 70 °C. The contactor is designed for high-load switching with a maximum short-time withstand 2440–996 A depending on duration and temperature.
Yes. With four main contacts and a robust 4P configuration, the AF305-40-11-12 handles motors up to 160 kW (AC-3) and supports up to 500 A AC-1 (or 350 A UL for general use) in appropriate voltages. Its surge protection and wide coil voltage tolerance reduce nuisance trips and improve uptime in packaging, conveying, and processing lines where power stability and quick motor control are critical.
The AF305-40-11-12 carries CE and UKCA declarations, UL/cUL certification for multiple voltage configurations, and RoHS compliance. It also aligns with REACH declarations and various international certifications (EAC, CB, BV, ABS, etc.), supporting safe deployment across global facilities and helping meet regulatory and customer-specific requirements.
The design reduces energy use via AF technology with a broad control range, lowering panel energy losses. Mechanical durability is rated at up to 5 million cycles, lowering replacement frequency. Built-in surge protection reduces equipment faults, and modular add-ons simplify future upgrades. Together, these factors contribute to lower maintenance costs, reduced downtime, and a faster return on investment in demanding production environments.
