31074-400-38 - Square D Coil Description
31074-400-38 - Square D Coil
If a contactor or starter suddenly stops working, there’s a good chance the coil is the culprit—not the entire unit. The 31074-400-38 replacement coil is designed to solve that exact problem without forcing you into a full replacement.
This coil fits Type S contactors and starters, including common setups used in motor control and lighting applications. Swap it in, and you can run your system on 110/120V AC (50/60 Hz) without changing out the whole assembly. That’s time saved, money saved, and less disruption overall.
It’s built the way you’d expect for real job-site conditions. The coil is fully encapsulated, so it holds up better against dust, vibration, and everyday wear. On startup, it delivers solid inrush power to pull in cleanly, then settles into efficient operation without excessive draw. Nothing flashy—just dependable performance where it counts.
Install is straightforward too. The screw clamp terminals keep wiring secure, and there’s no complicated setup involved. If you’ve replaced a coil before, this will feel familiar.
