31074-400-57 - Square D Coil Description
31074-400-57 - Square D Coil
If your contactor suddenly stops pulling in, there’s a good chance the coil is the issue—not the entire unit. And replacing the whole contactor? That’s usually overkill.
The 31074-400-57 replacement coil is built for Type S contactors and starters, giving you a straightforward way to get things working again without a full replacement. Swap out the failed coil, match your control voltage, and you’re back up and running.
This coil is rated for 440/480V AC (50/60 Hz) and is commonly used across industrial and commercial systems. It’s fully encapsulated, which helps protect it from dust, vibration, and general wear—things you deal with every day in the field. The screw clamp terminals keep installation simple and secure, whether you’re doing a quick repair or scheduled maintenance.
It’s a solid fit for equipment like 8502SE contactors, 8536SE starters, 8903SQ lighting contactors, and 8910DPA definite purpose contactors—so if you’re working with any of those, this is likely the coil you need.
