Description

The ABB AF80-30-11 is a high-duty 3-pole contactor from ABB’s AF-Line range, providing motor switching capability for loads up to 37 kW at 400 V AC (AC-3) or 50 hp at 480 V UL, with an AC-1 general-purpose switching rating of 150 A at both IEC and UL-A600 ratings. This contactor features two built-in auxiliary contacts and screw terminal connections, making it immediately ready for use in motor control circuits requiring run indication, interlocking, or fault signalling. Its substantial current rating positions it as a suitable choice for large industrial motors driving pumps, fans, compressors, and process machinery.

Rated at 1000 V IEC or 600 V UL, the AF80-30-11 complies with IEC 60947-4-1 and UL 508, ensuring its suitability for international electrical installation projects. It incorporates ABB’s wide-range coil technology, accepting 100 to 250 V AC at 50/60 Hz or 100 to 250 V DC, making this single product suitable for a wide range of control voltage systems without the need for bespoke coil voltage variants. The durable silver alloy contact system ensures reliable, long-life performance under the thermal and electrical stresses of high-current motor switching duty.

The AF80-30-11 is compatible with ABB’s TF96 series electronic overload relays, which mount directly onto the contactor body to create a co-ordinated motor protection starter unit. The two built-in auxiliary contacts enable interlocking with other contactors in star-delta or reversing starter configurations, as well as PLC run feedback and alarm output signalling. This contactor is a preferred choice for engineers designing motor control solutions for water and wastewater pumping stations, large HVAC systems, heavy industrial processes, and power distribution switchboards requiring reliable medium-voltage motor switching.
