ABB AF2050-30-11-70 Contactor - UL/CSA 1000 V 2050 A
Part Number: 1SFL707033R7011
Quick Summary
The AF2050-30-11-70 Contactor is a high-capacity 3-pole switch designed to control heavy motor circuits in industrial automation. In practice, voltage fluctuations and panel energy waste can cause nuisance trips and unstable operation. It carries CE and UL/CSA approvals and IP20 coil terminals, with RoHS and REACH compliance to help meet regulatory requirements. For OEMs and panel builders, the wide control-voltage range of 100-250 V AC/DC minimizes panel sizing and energy use, while the block design enables straightforward installation and scalable expansion with add-on auxiliary contacts. This combination supports reliable motor starting and lower total cost of ownership across demanding applications.
Product Information
Extended Description
1SFL707033R7011 ABB: The AF2050-30-11-70 CT19001 is a 3 pole - 1000 V IEC or 1000 V UL contactor with pre-mounted auxiliary contacts and Main Circuit Bars, switching power circuits up to 2050 A (AC-1) or 2100 A UL general use. Thanks to the AF technology, the contactor has a wide control voltage range (100-250 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 coil supports 100-250 V AC, 100-250 V AC with 50/60 Hz or DC operation. Coil operating limits are 0.85 x Uc to 1.1 x Uc (θ ≤ 70 °C). The unit provides 1 NO and 1 NC auxiliary contacts in addition to the 3 NO main contacts. Use standard wiring with Main Circuit bars and suitable ferrules or solid conductors as specified (Auxiliary circuit: 2x0.75-2.5 mm² ferrule or 2x1-4 mm² solid/stranded).
For AC-1 at 1000 V, Ie is 2050 A at 40 °C, 1750 A at 55 °C, and 1500 A at 70 °C. For AC-3 at 1000 V, Ie is 425 A at 55 °C. At 690–1140 V and 40 °C, Ie remains 2050 A for AC-1, with reductions at higher temperatures as specified. This makes the device suitable for high-starting current motor applications with temperature compensation.
Yes. With 3P main contacts and 2050 A AC-1 capability, the AF2050-30-11-70 is designed for heavy motor control in OEM and panel-builder contexts. Its surge protection, wide control range, and pre-mounted auxiliary contacts simplify wiring and reduce panel footprint. The block-design supports cascading with add-on contact blocks, improving scalability for conveyors, pumps, blowers, and other heavy-duty loads.
Key certifications include CE Declaration of Conformity, UL/CSA certification for main circuit and general use, CCC/UKCA/EAC where applicable, RoHS II compliance, and REACH declarations. IP20 coil terminals and insulation ratings meet typical industrial safety standards, while the device’s 1140 V insulation and 8 kV impulse withstand support reliability in challenging environments.
AF technology provides a wide control voltage tolerance, reducing nuisance trips and panel energy consumption. The block design and compatibility with add-on auxiliary blocks simplify maintenance and future expansion, lowering downtime and spare-part costs. You also gain robust insulation, surge protection, and reliable operation across varying temperatures, contributing to lower total cost of ownership in manufacturing environments.
