The Square D 31041-400-51 is a magnetic coil for an electromechanical contactor, serving as the energizing element that drives the contactor’s switching action inside control circuits and motor control panels. This coil is rated at 240V, providing the electromagnetism needed to move the contactor’s contacts and control the flow of power to connected loads in industrial applications. This makes it suitable as a replacement or spare coil in existing Square D electromechanical contactor assemblies.
