8903LO20V02 - Square D Lighting Contactor

If you're looking for a straightforward way to control lighting in a commercial or industrial setup, the 8903LO20V02 lighting contactor is a solid, dependable option. It’s built to handle everyday lighting loads without overcomplicating things—exactly what you want when reliability matters more than bells and whistles.

This is an electrically held contactor, which simply means it stays engaged as long as power is applied to the coil. That makes it a good fit for systems where lights need to remain on for extended periods without interruption. It’s rated for 30 amps on fluorescent lighting and 20 amps on tungsten, so it covers a wide range of common applications.

One thing contractors and maintenance teams appreciate is how adaptable it is. The contacts can be changed from normally open to normally closed in the field, and the coil is interchangeable if your voltage requirements change. You’re not stuck replacing the whole unit just because one spec shifts.

It’s also designed with real-world use in mind. The open-style build makes it easy to install inside your preferred enclosure, and when it comes time for maintenance, both the coil and contacts can be swapped out without much effort. That can save you time—and frustration—down the line.
