8903SPO4V02 - Square D Lighting Contactor

8903SPO4V02 - Square D Lighting Contactor

If you’re managing a commercial or industrial lighting system, you already know one thing—control and reliability aren’t optional. The 8903SPO4V02 electrically held lighting contactor is built for exactly that kind of environment. Designed to handle up to 60 amps, this 5-pole contactor gives you the confidence to control large lighting loads without hesitation. Whether you're upgrading an existing setup or building out a new panel, this unit offers the kind of straightforward, dependable performance that keeps operations running smoothly.

What makes this contactor especially practical is its electrically held design—it stays engaged only while energized, making it ideal for automated lighting systems that rely on timers, sensors, or centralized controls. The included 110/120 VAC coil (50/60 Hz) is a standard, widely compatible option, and the interchangeable coil design means you’re not locked into one configuration if your needs change down the line. Add in its open-style construction, and you’ve got the flexibility to install it your way—inside a custom enclosure or as part of a larger control system.

From a maintenance standpoint, this unit is built with longevity in mind. Replacement contact kits are available, which means you can extend the life of your equipment instead of replacing it outright. For professionals who value uptime and efficiency, that’s a major advantage.
