ABB AF Contactors - AC and DC Electronic Coil
November 23 2011
AF contactors can manage large control voltage variations. One coil (e.g. 100...250 V 50/60 Hz - DC) can be used for different control voltages used worldwide without any coil change.
- Unique contactor whatever the AC or DC control supply mode
- Extended coil operating limits to manage large voltage variations
- Only 4 coils with wide voltage range covering voltages between 24...500 V 50/60 Hz and 20...500 V DC 
- Built-in surge protection
- From 30% up to 80% of reduction of AC pull-in coil consumption
- Direct control by PLC-output 24 V DC 500 mA
- Low AC and DC holding consumptions
- Extended features with AF..Z type: voltage sag & dips withstand in the control supply
Main Benefits
- Greater product availability, reduction of stocks and increased inventory turnover
- Simplified design with an unique AC/DC contactor frame size
- No interface relay coupled with PLC and no extra surge suppressor required anymore
- Reduced panel consumption, less fans, smaller control transformers
- Improved operational reliability of customer equipments
