8903LO80V02 - Square D Lighting Contactor

If you’re running a lighting system that needs to be dependable day in and day out, the 8903LO80V02 electrically held lighting contactor is a solid, no-nonsense choice. Built for commercial and industrial lighting control, this 8-pole unit handles multiple circuits without overcomplicating your setup. It’s rated for up to 30 amps on fluorescent lighting and 20 amps on tungsten, making it a practical fit for a wide range of applications where consistent switching matters.

This model uses an electrically held design, so it stays engaged as long as power is applied—simple and predictable. It comes equipped with a 110/120 VAC coil, and if your requirements change later, you’ve got the option to swap in a different coil voltage. One thing contractors and maintenance teams appreciate is how easy it is to work on. The contacts can be converted in the field from normally open to normally closed, and both the coil and contacts can be replaced without much hassle. The open-style design also makes access easier when it’s installed in a panel.

Overall, this is the kind of component you install and don’t have to think much about afterward—it just does its job controlling lighting where and when you need it.
