The Allen-Bradley 551684A-SC Coil is an electromagnetic operating coil (Series SC) that actuates contactors, relays, solenoids, and other electrically operated devices in industrial control equipment. It features a copper winding with an insulated coil assembly (MPN 551684A-SC) and is designed for application-dependent mounting in motor control systems, electrical control panels, and machinery, delivering magnetic actuation in industrial control setups. As a legacy/surplus component, it serves as a replacement coil for OEM 551684A-SC in manufacturing, automation, material handling, and process-control environments.
