31063-409-47 - Square D Coil Description
31063-409-47 - Square D Coil
If a contactor or starter stops working, the coil is often the first thing to check—and in a lot of cases, it’s the only part that needs replacing. The 31063-409-47 coil gives you a straightforward way to get your equipment back in service without tearing everything out and starting over.
This coil is made for use with 8502 Type SD contactors, 8536 Type SD starters, and 8903 Type SP lighting contactors, so if you’re working with any of those, it’s a direct fit. It runs on 220/240V AC (50/60 Hz) and installs using standard screw clamp connections—nothing complicated or time-consuming.
One thing worth noting: the coil is fully encapsulated. That matters more than people think. It helps keep out dust, moisture, and general shop grime, which is usually what shortens the life of electrical components in the first place. So once it’s in, you’re not coming back to fix the same issue anytime soon.
Bottom line—if the rest of your equipment is still in good shape, this lets you fix the problem without overspending or overthinking it.
