Allen-Bradley 72A288 Electromechanical Relay Coil is a replacement magnet coil for Allen-Bradley size-2 contactors, compatible with 2-, 3-, and 4-pole configurations in Series K. The coil is rated for 480V AC at 60 Hz or 440V AC at 50 Hz, matching common industrial power systems. It energizes the contactor to switch heavy loads such as motors and industrial equipment, using the exact coil voltage required for the 72A288 assembly. Use this coil as a direct replacement for 72A288 to maintain correct actuation voltage and reliable operation in your control panel.
