It complies with IEC 60947-4-1, UL 60947-4-1, and EN 50155, providing rail and industrial confidence across global installations. Coupled with DIN-rail mounting, add-on auxiliary blocks, and compact footprint, it delivers efficiency, scalability, and easier maintenance for modern control panels.
Product Information
Extended Description
1SBL157060R1410 ABB: The AF12B-30-10RT-14 is a 3 pole - 690 V IEC or 600 UL contactor with 1 built-in auxiliary contact and Ring-Tongue Terminals, controlling motors up to 5.5 kW / 400 V AC (AC-3) or 7-1/2 hp / 480 V UL and switching power circuits up to 28 A (AC-1) or 28 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.

FAQs
The AF12B-30-10RT-14 is designed for DIN rail mounting on TH35-15 or TH35-7.5 rails. It also accommodates secure screw mounting (2 x M4 screws, diagonally placed). This enables fast installation in standard control panels and ensures consistent alignment with adjacent devices for reliable wiring and easy maintenance.
For AC-1 duty at 690 V, the device provides up to 28 A, with rated operational currents shown across temperature ranges (60 and 70 °C depending on voltage). For AC-3 duty, the unit handles up to 12 A at various voltages (e.g., 380–690 V). The 3-pole main circuit supports switching of motors up to 5.5 kW (AC-3) with a 1 NO auxiliary contact for feedback.
Yes, the AF12B-30-10RT-14 includes built-in surge protection. The coil is compatible with 250-500 V AC, 50/60 Hz, and DC operation, enabling broad control voltage tolerance and reduced risk of nuisance tripping in networks with voltage fluctuations.
The product conforms to IEC 60947-4-1 and IEC 60947-5-1, with UL 60947-4-1 and EN 50155 recognition for railway applications. It also references CE/UKCA declarations, ensuring compatibility with global regulatory requirements across industrial and rail environments.
The built-in surge protection, compact design, and AF technology reduce external components, wiring complexity, and energy waste, improving uptime and reducing panel space. ROI improves through lower wiring costs, fewer nuisance trips due to voltage fluctuations, and easier future expansion via add-on auxiliary blocks.
