AF09 4-pole contactors are used for controlling power circuits up to 690 V AC and 440 V DC. They are mainly used for controlling non-inductive or slightly inductive loads (i.e. resistance furnaces...). AF... contactors include an electronic coil interface accepting a wide control voltage Uc min. ... Uc max. Only four coils cover control voltages between 24...500 V 50/60 Hz or 20...500 V DC. AF contactors can manage large control voltage variations. One coil can be used for different control voltages used worldwide without any coil change. AF contactors have built-in surge protection and do not require additional surge suppressors. The AF... series 4-pole contactors are of the block type design. - Main poles and auxiliary contact blocks: 2 N.O. + 2 N.C. main poles, front and side-mounted add-on auxiliary contact blocks (mechanically-linked auxiliary contacts compliant with Annex L of IEC 60947-5-1. N.C. mirror contacts compliant with Annex F of IEC 60947-4-1) - Control circuit: AC or DC operated - Accessories: a wide range of accessories is available. Note: - AF..-..-..-11 not suitable for a direct control by PLC-output. - AF..-..-..-11 type available in some countries: please consult your ABB representative.

Compared with the traditional technology, AF series control coil can provide multiple advantages. At the same time, with the help of ABB's wide range of product models, the electronic control coil has a reasonable configuration in each application. 

• The product model is streamlined and helps optimize logistics and reduce management costs
• The same model is suitable for almost all applications in the world and provides global technical support
• The coil energy consumption is reduced by 80%, and energy cost is greatly saved
• Using AF technology, effectively deal with the control voltage drop or disappear in a flash, to ensure normal operation
