The ABB AF38Z-30-00K-21, product code 1SBL296005R2100, is a compact and energy-efficient three-pole power contactor designed for controlling three-phase motors and other industrial power circuits. Its three normally open main contacts provide dependable switching for machinery, process equipment and automated control systems.
Part of the advanced ABB AF..Z contactor series, the AF38Z-30-00K-21 features an electronic coil interface accepting 24–60 V AC at 50/60 Hz or 20–60 V DC. It supports direct control from a suitable PLC output, provides reduced holding-coil consumption and incorporates surge protection without requiring an external suppressor.
With a rated motor power of 18.5 kW at 380–415 V AC-3, a rated operational current of 38 A and push-in spring terminals, this contactor combines dependable motor switching with efficient, time-saving panel installation.
Contactors such as the ABB AF38Z control power to three-phase motors by opening and closing the main electrical circuit in response to a low-power control signal. This enables remote switching and integration with programmable controllers, motor starters, relays and automated machinery.
The AF..Z electronic coil interface supports both AC and DC control supplies while reducing holding-coil energy consumption. Integrated surge suppression, voltage-dip tolerance and push-in spring terminals help deliver reliable operation with efficient control-panel installation.
