New energy saving control gear family

ABB has introduced a new generation of control gear, including contactors, coupling energy saving technology with simplified specification and ordering.

A key feature of the new range is the use of ABB’s AC/DC electronic coil technology. Covering both AC and DC voltages between 24…500 V 50/60 Hz and 20…500 V DC, the coil has reduced the number of contactor types by 90%, from 2,500 to just 250 parts. This makes it particularly suitable for OEMs and distributors by making the range easier to specify and stock. With its reduced AC pull-in coil consumption from 30% (for AF) to 80% (for AF…Z), the contactors deliver less losses per phase and generate less heat, enabling users to improve the energy efficiency of their panel systems.

For installers, the standardised 45mm housing enables it to be easily integrated into an existing installation. Around 33% narrower than other products on the market, the range also helps save space, enabling operators to reduce both the overall size and cost of their panels. With no need for mounting plates, the cost and time of installing reversing or star-delta starters can now be reduced, with installation times typically cut by over 50%.

A key benefit of the AF contactor range is its ability to manage the effects of unstable voltage conditions caused by poor network conditions, motor inrush current or voltage drops along cable lengths. As well as extended coil operating limits, the new AF contactors feature built-in surge protection, eliminating the need for an extra surge suppressor and providing added reliability and safety in the event of voltage fluctuations.

With a choice of left, right, top or bottom mounting options, the AF contactor range also offers groundbreaking flexibility during installation, by removing the disruption caused by incompatible or wrongly sized products.
