The AF09ZB-40-00RT-21 is a 4-pole contactor from the AFZ low-consumption series, designed for switching resistive or slightly inductive loads. It features four normally open (4NO) main poles and is operated by an electronic coil that accepts a control voltage range of 20-60V DC or 24-60V AC. This contactor has an IEC AC-1 rated operational current of 25 A at 40°C and a UL/CSA general purpose rating of 25 A at 600V. Its low power consumption and reliable AC/DC electronic control make it suitable for a variety of power circuit switching applications.
