ABB LTD GBCON 1SBL277001R1300 3 Pole AF30 contactor is used for controlling power circuits up to 690V AC and 220V DC. They are mainly used for controlling 3 Phase motors, non-inductive or slightly inductive loads. AF contactors include an electronic coil interface accepting a wide control voltage Uc min, Uc max. Only four coils cover control voltages between 24 to 500V 50/60Hz or 20 to 500V 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 1-stack 3 Pole contactors are of the block type design. Main poles and auxiliary contact blocks: 3 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). AC or DC operated control circuit.
