Thank you for reading AF contactors

Advanced Functionality

Flexible AF
AF contactors are perfect for AC or DC motor starting applications and for solutions where space is limited. Multiple configurations can be achieved within the AF product family. For example, interlocked reversing pairs require no spacing between contactors meaning you can fit more functionality into cabinets or other small enclosures. Drawings and coordination tables can be accessed online, simplifying your design and assembly process.

Reliable AF
The AF contactor ensures distinct operation in unstable networks and signifies a major advance in motor control and power switching. Voltage sags, dips and surges pose no threat.

Efficient AF
An 80% reduction in contactor coil energy consumption means less heat in the enclosure, allowing the use of smaller panels and more compact transformers.

Compact AF
ABB has reduced the number of contactor coils to just four across the whole AF range, reducing its width by up to 30%. This in turn allows the use of smaller cabinets, without compromising on heat dissipation.

Versatile AF
With conventional contactor technology, different contactors were needed for different network voltages. ABB has managed to reduce the number of contactor coils to just four. The total number of product variants has been reduced by up to 90% for streamlined ordering and inventory, providing a logistical advantage for customers.

Advanced Functionality

Functional AF
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 AF technology the surges are handled by the contactor itself, and so 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.

Quiet AF
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.

Safe AF
The AF contactor and motor protection range is compatible with all major national and international standards and is available worldwide. One contactor coil now handles 100 V – 250 V, AC/DC for use in Europe or Asia as well as North America.
