8536SEO1V02 - Square D Magnetic Starter

8536SEO1V02 - Square D Magnetic Starter

The 8536SEO1V02 NEMA Size 3 motor starter is a dependable option for controlling 3-phase AC motors in demanding environments. Built for full-voltage starting and stopping, this 90 amp, 3-pole non-reversing starter is commonly used in applications where consistent motor performance matters—think pumps, compressors, HVAC systems, and production equipment. It’s rated for up to 50 HP at 460/575 VAC, giving you the capacity needed for heavier loads without overcomplicating your setup.

This unit uses a melting alloy overload relay with Type CC thermal units, which helps protect your motor from overheating and overcurrent conditions. That’s one of those features you don’t think about—until it prevents a failure. The 110/120 VAC coil is wired for separate control, making it easier to integrate into existing systems or new builds. Since it’s an open-type starter, it’s meant to be installed inside an enclosure that fits your application.

If you’re looking for a straightforward, proven NEMA motor starter that does its job without unnecessary complexity, this one checks the right boxes.
