AF12 contactors are 1-stack, 3-pole contactors with a block type design. Features and Benefits: -Include an electronic coil interface accepting a wide control voltage -AF contactors can manage large control voltage variations making them incredibly versatile, one coil can be used for different control voltages used worldwide without any coil change -Built-in surge protection and so, do not require additional surge suppressors Typical Applications: -Used for controlling power circuits up to 690 V ac and 220 V dc -Used for controlling 3-phase motors, non-inductive or slightly inductive loads Notes: -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
