What this contactor is
The ABB AF26ZR-30-22-21 is a 3-pole reversing contactor rated at 25.3 A, carrying the REV suffix for the reversing variant. It's part of the AF26 series, designed for motor switching and load management in industrial control panels.
What the 25.3 A rating means for fit
The 25.3 A rating is the continuous thermal current (Ith) for the main contacts. For motor duty (AC-3), derate to the motor full-load current.
Deployment context
This reversing contactor mounts on a DIN rail inside an enclosure, with the mechanical interlock built into the REV variant to prevent simultaneous closure of forward and reverse contactors. It's used in control panels for conveyor direction reversal, pump sequencing, or any application requiring motor direction change.
