ABB recently introduced its new line of AF Range contactors featuring four coils in the entire voltage range for 90% fewer stock keeping units (SKUs) than conventional contactor lines. The line’s single-coil code covers all global network voltages; four coils cover 24 VAC, 20 VDC to 500 VAC/DC.
ABB’s line of AF Range contactors range from 4 kW/5 hp, for small motors, to model AF2650, for high-power switching, which is the world’s largest single-case block contactor.
“Our new coil design simplifies engineering and significantly reduces inventory variation, while meeting global voltage and frequency requirements,” says Steven Sundlov, ABB business unit manager, control products. “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% reduction of the coil’s energy consumption, the AF Range contactor is 30& 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 and DC for use in North America, Europe and Asia.
