8903SQO2V02 - Square D Lighting Contactor

8903SQO2V02 - Square D Lighting Contactor

When you’re dealing with lighting control in a commercial or industrial setup, you don’t want surprises. The 8903SQO2V02 electrically held lighting contactor is built for exactly that kind of reliability. Rated for 100 amps, this 3-pole unit with three normally open contacts is designed to handle larger lighting loads without overcomplicating the install or maintenance.

Because it’s electrically held, the contactor stays engaged as long as the coil is energized—making it a solid choice for systems that need lights on consistently without interruption. It comes equipped with a 110/120V AC coil (50/60 Hz), which covers most standard applications, and if your setup changes down the line, there are other coil options available.

Another thing contractors tend to appreciate is how serviceable this unit is. You don’t have to replace the whole contactor if something wears out—both the coil and contacts can be swapped out pretty easily. The open-style design also gives you flexibility to mount it in the enclosure that makes the most sense for your project. It’s a straightforward, dependable piece of gear that does its job without getting in your way.
