ABB has released 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 groundbreaking ac/dc electronic coil technology. Covering both ac and dc voltages between 24 to 500V 50 and 60Hz and 20 to 500Vdc, the coil has reduced the number of contactor types by 90%, from 2,500 to just 250 parts. This makes the range both 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 installations.For installers, the new range’s standardised 45mm housing also enables it to be easily integrated into an existing installation. Around 33% narrower than other products on the market, the range 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%.
