The ABB AF38Z-30-00-30 is a three-pole electrical contactor from the AF38Z series, with a 24 VDC coil. It is classified under Contactors and Starters / Electrical Contactors, and sits within the Circuit Breakers, Fuses & Protection top category.
The 24 VDC coil is common for PLC-driven output cards; verify the coil suppression polarity (free-wheel diode) before energizing to avoid back-EMF damage to the digital output.
