31063-409-57 - Square D Coil Description
31063-409-57 - Square D Coil
If your contactor or starter suddenly stops working, chances are the coil is the culprit—and replacing the entire unit is overkill. The 31063-409-57 replacement coil gives you a smarter, faster, and far more cost-effective fix. Designed specifically for Type S contactors and starters, this coil lets you restore full functionality without tearing out and replacing expensive equipment.
Built for 440/480V AC applications (50/60 Hz), this coil delivers reliable pull-in performance with strong inrush power and efficient holding consumption. In plain terms: it energizes quickly, runs efficiently, and keeps your system operating the way it should. The fully encapsulated design helps shield internal components from dust, moisture, and everyday wear, making it a dependable choice in real-world industrial environments—not just on paper.
Installation is refreshingly simple thanks to secure screw clamp terminals, so whether you're handling a planned maintenance job or a time-sensitive repair, you can get in, swap it out, and get back online fast. If you're trying to minimize downtime and avoid unnecessary costs, this is exactly the kind of replacement part you want on your shelf.
