31063-409-38 - Square D Coil
When a contactor or starter fails, it’s often just the coil—and replacing the entire unit is overkill. The 31063-409-38 replacement coil gives you a smarter, faster fix. Designed for Type S NEMA Size 2 contactors and starters, this coil lets you restore your equipment without the cost and hassle of a full replacement.
Built for 110/120V AC control circuits (50/60 Hz), this coil is a direct-fit solution for 8502SD contactors, 8536SD starters, and 8903SP lighting contactors. Whether you're maintaining an industrial motor control system or troubleshooting a lighting panel, this replacement coil gets the job done efficiently.
Performance-wise, it delivers where it counts. With strong inrush power up to 311 VA, it ensures reliable engagement every time, while low sealed consumption (as low as 36 VA) helps keep energy usage in check. The fully encapsulated design adds an extra layer of protection against dust, moisture, and everyday wear—making it a dependable choice for different types of environments.
