8903SPO3V02 - Square D Lighting Contactor

When you’re dealing with large lighting systems, you don’t want to second-guess your equipment. The 8903SPO3V02 electrically held lighting contactor is built to handle that responsibility with straightforward, dependable performance. Rated for 60 amps and equipped with four normally open poles, it’s designed to manage multiple lighting circuits without overcomplicating your setup. Whether you're upgrading an existing system or building out a new panel, this contactor gives you a clean, reliable way to control power where it matters.

This model uses an electrically held coil, meaning it stays engaged as long as power is applied—ideal for lighting applications that need to remain on for extended periods. It comes standard with a 110/120 VAC 50/60 Hz coil, and the interchangeable coil design makes it easy to adapt if your voltage requirements change down the line. The open-style construction keeps things flexible during installation, especially in custom enclosures or control panels. And when maintenance comes into play, available replacement contacts and accessories help keep downtime to a minimum without replacing the entire unit.
