AF 3-pole contactors

Secure uptime and optimize stocks with AF latest technology up to 2650 A

Featuring AF technology as standard, AF contactors establish a new industry benchmark. The electronically controlled coil offers multiple benefits over conventional alternatives, and together with ABB's wide product offering, an optimal configuration, every time.

Main benefits

  • Optimize logistics  and cut administration costs with fewer product variants to handle
  • Access global support and use the same products in all parts of the world: the 100 - 250 V, AC/DC coil covers all standard network voltages
  • A reduction of the coil's energy consumption by 80% lets you save energy
  • Secure your uptime by letting the AF technology overbridge voltage drops and sags.

Main features

  • Up to 560 kW - 400 V AC-3, 900 hp - 480 V and 2650 A - 690 V AC-1, 2700 A - general use
  • Only 4 coils cover 24 V - 500 V AC and 20 V - 500 V DC
  • Screw, spring and ring tongue connection types
  • Built-in surge suppression
  • Connection sets and interlock unit for reversing and star-delta starter for an easy, fast and secure assembly of starters
  • Mirror and mechanically linked contacts.

Reliable in all networks

The electronic system within the AF contactor rectifies the AC or DC control circuit voltage to a DC control voltage that is applied on the coil. The contactor is safely operated in an always optimized condition making it virtually noise free.

Four coils for the entire voltage range

The AF contactor features both AC and DC support. With the complete AF contactor range, functionality is improved. Still, the total number of product variants compared to a conventional range is reduced by 90%. Only four coils are required to cover 24 V AC, 20 V DC-500 V AC/DC.

Wide control voltage range

With conventional contactor technology, different contactors were needed for different network voltages. Thanks to the wide operating range of the AF contactor it can operate just as well in Europe as in Asia or North America. The core coil of the AF contactor range covers 100-250 V, AC/DC and 50/60 Hz.

Built-in surge suppression

With conventional contactor technology it is recommended to use an external surge suppressor, an accessory that could cost as much as half the contactor itself. With the AF technology the surges are handled by the contactor itself and the surge never reaches the control circuit. Neither the surge suppressor nor the actual surge has to be considered anymore. One less product and one less complication to worry about.
