AF Contactors

AF contactors - 9-1250A (AC-3)

• Optimized logistics: With its contactor and motor protection range, ABB has managed to reduce the number of contactor coils to just four. Total number of product variants has been reduced by up to 90%. This simplifes the customers' logistics while cutting storage and administration costs
• Continuous operation:
  • 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.
• Speed up your projects:
• Use the same part number in Europe, Asia and North America as one contactor coil now handles 100 V – 250 V AC / DC, 50 / 60 Hz.
• By reducing contactor coil energy consumption by up to 80%, panels can be built smaller and transformers more compact
• Reliable in all networks: The electronic system within the AF contactor continuously monitor the current and voltage apply to the coil. The contactor is safely operated in an always optimized condition and hum free.
• Four coils for the entire voltage range: AF contactors feature both AC and DC control in the same product. 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 are 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 of the contactor. With the AF technology, the surges are handled by the contactor and never reach the control circuit. One less product and one less complication to worry about.
• Easy, fast and secure starters assembly: The AF contactor range is perfect for motor starting applications and for solutions where space is limited. You can create any motor starting type and save assembly time with a complete range of accessories and connection sets
• Compact size: The AF contactor is compact in size and has had its width reduced by up to 30% thanks to an 80% coil consumption reduction.
• Save space: Interlocking reversing pairs require no spacing between contactors, meaning you can fit more functionality into cabinets or other enclosures
• Protect from overload in all conditions: Select thermal overload relays (trip class 10) or electronic overload relays (trip class 10E, 20E, 30E in the same product) to protect your motors against overload and phase failure
• Easy to use accessories: 1-pole, 2-pole and 4-pole auxiliary contact blocks, front or side mounted, are available for a great flexibility up to 96 A. Furthermore, 116 to 2650 A contactors can take up to 2 side mounted auxiliary contact blocks without adding to its width. Coil connection terminals, mechanical and electrical interlocks and electronic timers are easily connected through he snap-to-connect function.
• Great flexibility for coil terminal access: Contactors up to 96 A offer free choice of coil terminal access from top, bottom, both top and bottom or front.
• Simple connection and maintenance: The main terminals of AF116 … AF2650 contactors are at the contactors's back to facilitate your bus bars connections. It also allows easy contact inspection and maintenance from AF400 and above.
