The AF Series of contactors are used for controlling power circuits up to 600 V AC and 240 V DC. They are mainly used for controlling 3‑phase motors, non‑inductive or slightly inductive loads. 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 (e.g., 100...250 V 50/60 Hz ‑ DC) 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 built‑in N.C. auxiliary contact is a mirror contact in compliance with annex F of IEC 60947‑4‑1.

Contactors contain integrated, electronically controlled coils which reduce energy consumption. Contains push‑in spring terminals which allow for fast, easy wiring. Contactors can overbridge voltage drops and sags.
