Original Press Release

New ABB AF Range Contactors Reduce SKUs by 90 Percent

Press release date: May 21, 2014

Five Coil Codes Cover All Global Network Voltages

NEW BERLIN, Wisc. — The new line of AF Range contactors from ABB Low Voltage Products division features four coils in the entire voltage range for 90 percent fewer stock keeping units (SKUs) than conventional contactor lines. The line’s single-coil code covers all global network voltages; four coils cover 24VAC, 20VDC to 500VAC/DC.

ABB’s line of AF Range contactors range from 4kW/5hp, for small motors, to model AF2650, for high-power switching, which is the world’s largest single-case block contactor.

“With a rating of nine amps to 2,700 amps, the ABB AF Contactor offers the widest range of single case contactors in the world” said Steven Sundlov, ABB business unit manager, control products. “Our new coil design simplifies engineering and significantly reduces inventory variation, while meeting global voltage and frequency requirements.  With its continuous monitoring, reduced power consumption and integral surge protection, the ABB AF contactor operates safely, reliably and efficiently.”

The electronic system within the AF Range contactor rectifies the AC or DC control voltage to a DC control voltage that is applied on the coil; the contactor operates safely and is always in an optimized condition, making it free of noise.

Additional features of the new line include:

Built-in surge suppression: The AF Range contactor manages surges, eliminating the need to use external surge-suppression devices
Compact size: Due to an 80-percent reduction of the coil’s energy consumption, the AF Range contactor is 30 percent narrower than conventional contractors, enabling applications where space is limited
Ease of maintenance: The AF Range contactor’s coil terminals are accessible from the front of the unit; cables and bars do not need to be disconnected for voltage measurement or service
Ease in accessorizing: Accessories, including coil connection terminals, mechanical and electrical interlocks, and electronic timers, are easily connected through the AF Range contactor’s snap-to-connect function

The AF Range contactor complies with all major national and international standards. One contactor coil now handles 100V to 250V AC/DC for use in North America, Europe and Asia. 

ABB’s new line of AF Range contactors is available now from authorized ABB distributors.
