8903SMO1V02 - Square D Lighting Contactor

8903SMO1V02 - Square D Lighting Contactor

The 8903SMO1V02 lighting contactor is a practical choice for controlling lighting circuits in commercial and industrial settings. It’s a 30 amp, 2-pole unit with normally open contacts, designed to switch lighting loads reliably without adding unnecessary complexity to your system.

This is an electrically held contactor, which means it stays closed only while the coil is energized. If power is lost, the contacts open automatically—something that’s often required in lighting control applications for safety and energy management. It comes equipped with a 110/120 VAC 50/60 Hz coil, and if your setup changes, the coil can be replaced without much effort.

Another thing worth noting is how serviceable this unit is. The coil and contacts are easy to access and swap out, so you’re not replacing the whole device for routine maintenance. Its compact, open-style design also makes it a good fit inside control panels or custom enclosures where space and flexibility matter.

If you need a straightforward, dependable lighting contactor that does exactly what it’s supposed to do, this one gets the job done.
