8903LXO1000V02 - Square D Lighting Contactor

If you’re managing large-scale lighting and need control that’s reliable without being wasteful, the 8903LXO1000V02 lighting contactor is built for exactly that job. This mechanically held lighting contactor gives you precise switching for multiple lighting circuits—without constantly drawing power to stay engaged. In other words, it works smarter, not harder.

Designed for commercial and industrial environments, this 10-pole unit handles up to 30A fluorescent and 20A tungsten loads, making it a go-to solution for everything from office buildings to warehouses. And because it uses a mechanically held mechanism, power is only used when switching states—not continuously—helping reduce energy usage and extend component life.

What really makes this unit stand out is its flexibility in the field. Need to change contact configuration? You can convert contacts from normally open (NO) to normally closed (NC) without replacing the unit. Maintenance is just as straightforward, thanks to easily replaceable coils and contacts, which means less downtime and fewer headaches.
