8903SQO1V02 - Square D Lighting Contactor

The 8903SQO1V02 from Schneider Electric is a solid, no-nonsense lighting contactor built for handling bigger lighting loads in commercial and industrial setups. It’s rated for 100 amps and uses a 2-pole configuration, which is pretty standard for this kind of application.

This model is electrically held, meaning it stays energized as long as the control circuit is powered—something you’ll want in systems that need lights on for extended periods without interruption. The open design keeps things simple. You can get eyes on it quickly, troubleshoot faster, and swap or service parts without dealing with a bulky enclosure.

It runs on a 120V coil (60/50 Hz), so it fits right into most existing control setups without needing special adjustments. Overall, it’s a practical choice if you’re looking for something dependable that just does its job without overcomplicating things.
