AF contactors for motor starting and power switching up to 2650A
The latest technology of electronically controlled coil is our standard
It offers multiple benefits over conventional alternatives and together with ABB's wide product offering it is an optimal configuration every time.


Optimized logistics -- Cut your costs
With its contactor and motor protection range ABB has managed to reduce the number of contactor coils to just four.
Total number of product variants has been reduced by up to 90%.
This simplifies the customers' logistics while cutting storage and administration costs.


Continuous operation -- Secure uptime
Prevent stoppages caused by voltage fluctuations.
The AF contactor ensures distinct operation in unstable networks and signifies a major advance in motor control and power switching.
Voltage sags / dips / surges pose no threat.
The AF contactor secures your uptime.


Speed up your projects -- Simplify design
Use the same part number in Europe Asia and North America as one contactor coil now handles 100 V - 250 V AC (50 / 60Hz) / DC.
By reducing contactor coil energy consumption by up to 80% panels can be built smaller and transformers more compact.


Reliable in all networks -- The electronic system within the AF contactor continuously monitor the current and voltage apply to the coil.
The contactor is safely operated in an always optimized condition and hum free.


Four coils for the entire voltage range
AF contactors feature both AC and DC control in the same product.
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 are 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 (50 / 60 Hz)


Built-in surge suppression
With conventional contactor technology it is recommended to use an external surge suppressor that could cost as much as half of the contactor.
With the AF technology the surges are handled by the contactor and never reach the control circuit.
One less product and one less complication to worry about


Easy fast and secure starters assembly
The AF contactor range is perfect for motor starting applications and for solutions where space is limited.
You can create any motor starting type and save assembly time with a complete range of accessories and connection sets.


Compact size
The AF contactor is compact in size and has had its width reduced by up to 30% thanks to an 80% coil consumption reduction.


Save space
Interlocking reversing pairs require no spacing between contactors meaning you can fit more functionality into cabinets or other enclosures.


Easy to use accessories
1-pole / 2-pole / 4-pole auxiliary contact blocks front or side mounted are available for a great flexibility up to 96A contactors.
116 to 2650 A contactors can take up to 2 side mounted auxiliary contact blocks without adding to its width.
Coil connection terminals mechanical and electrical interlocks and electronic timers are easily connected through the snap-to-connect function.


Great flexibility for coil terminal access
Contactors up to 96 A offer free choice of coil terminal access from top / bottom / top + bottom / front only.


Simple connection and maintenance
The main terminals of AF116 to AF2650 contactors are at the contactors' back to facilitate your bus bars connections.
It also allows easy contact inspection and maintenance from AF400 and above.
