ABB AF Contactors

Product Description

Thermal Devices is an authorized distributor for ABB Low Voltage Control Products including all ABB Contactor products. The latest range of ABB’s contactors – the AF Series – establishes 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. Below are some of the benefits and features of the ABB AF contactor:

Globally Accepted

The AF contactor and motor protection range from ABB 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.

Optimizes logistics

With its contactor and motor protection range, 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%. This simplifies the customers’ logistics and cuts administration costs. When you choose the ABB AF Series contactors, your inventory SKUs are reduced significantly and the resulting consolidation offers opportunity for efficiency and cost savings

Simplify design

By reducing contactor coil energy consumption by up to 80%, panels can be built smaller and transformers more compact. All the features of the AF technology, along with access to drawings and coordination tables online, simplifies your de-sign and assembly process.

Secure uptime

Time to 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 and surges pose no threat. The AF contactor secures your uptime.

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 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 sup-pressor nor the actual surge has to be considered anymore. One less product and one less complication to worry about.

The AF contactor is compact

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

The AF contactor is flexible

AF09…AF370 is perfect for motor starting applications and for solutions where space is limited. Interlocked reversing pairs require no spacing between contactors meaning you can fit more functionality into cabinets or other small enclosures.

Coil terminal access in the front

The AF contactor has its coil terminals accessible from the front. The cables or bars do not have to be disconnected in order to perform voltage measurement or servicing work.

More functionality without adding width

The AF116 … AF2650 can take up to 2 side mounted auxiliary contact blocks without adding to its width and are delivered with 1 N.O. + 1 N.C. as standard.

Easy-to-use accessories

Contactors up to 96 A offer free choice of coil terminal access and can take side and front mounted auxiliary contact blocks. All the accessories: Coil connection terminals, mechanical and electrical interlocks and electronic timers are easily connected through the snap-to-connect function.
