31091-400-38 - Square D Coil Description
31091-400-38 - Square D Coil
If a coil goes bad, you don’t need to scrap the whole contactor or starter. The 31091-400-38 replacement coil is a simple fix that gets your equipment back up and running without the extra cost. It’s designed for Type S contactors and starters, so you can swap it in and keep things moving—no major overhaul required.
This coil also gives you flexibility. If you're working with different control voltages, replacing the coil is often all it takes to adapt your setup. It’s commonly used with 8502SF contactors, 8536SF starters, and 8903SV lighting contactors, making it a go-to option for maintenance teams and electricians who want a reliable, straightforward solution.
The coil is fully encapsulated, which helps protect it from dust, vibration, and everyday wear. Installation is simple thanks to screw clamp connections, and once it’s in place, it delivers consistent performance with solid inrush power and efficient operation.
