AF38 contactors are used for controlling power circuits up to 690 VAC and 220 VDC. They are mainly used for controlling 3 ph 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 500 V 50/60 Hz or 20 to 500 VDC. 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. NC 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..-30-..-11 not suitable for a direct control by PLC-output. AF..-30-..-11 contactor type available in some countries: please consult your ABB representative.
