31041-400-42 - Square D Coil

31041-400-42 - Square D Coil

When a contactor or starter stops working, it’s often just the coil—not the whole unit. The Schneider Electric 31041-400-42 replacement coil lets you fix the problem without replacing everything, saving both time and money. This coil is built for Type S contactors and starters, including popular 8502 and 8536 series models, as well as 8903SM lighting contactors. It’s rated for 110/120V AC (50/60 Hz), so it works in a wide range of standard control circuits. If you’re dealing with a failed coil or need to match a different control voltage, this is a straightforward solution that keeps your existing equipment in service. Installation is simple thanks to screw clamp terminals, and the encapsulated design helps protect the coil from dust, moisture, and general wear. Once installed, it delivers reliable pickup and holding performance, helping your system operate the way it should—without unnecessary downtime.
