Description AF09 ... AF38 contactors are mainly used for controlling 3-phase motors and power circuits up to 690 V AC and 220 V DC. These contactors are of the block type design with 3 main poles. – control circuit: AC or DC operated with electronic coil interface accepting a wide control voltage range (e.g. 100...250 V AC and DC), only 4 coils to cover control voltages between 24...500 V 50/60 Hz and 20...500 V DC - can manage large control voltage variations - reduced panel energy consumption - very distinct closing and opening. - built-in surge suppression - add-on auxiliary contact blocks for front or side mounting and a wide range of accessories.
