8538SBG12 - Square D Combination Starter

8538SBG12 - Square D Combination Starter

If you just need a reliable way to control and protect a motor without overthinking it, the 8538SBG12 combination starter gets the job done. It combines a contactor and overload protection into one enclosed unit, so you’re not juggling separate components or dealing with a complicated install.

This model is built on the 8536 frame, which has been around for a long time for a reason—it works. The 120V AC coil fits into most standard control setups, and the 3-pole design makes it a good match for typical three-phase applications. With a 3 HP rating at 230V, it’s commonly used in everyday equipment like pumps, fans, and small machinery.

The NEMA 1 enclosure is designed for indoor use, keeping the internal components protected while still being easy to access when you need to check or service it. Nothing flashy here—just a straightforward, dependable starter that does what it’s supposed to do.
