8903LXO40V02 - Square D Lighting Contactor

8903LXO40V02 - Square D Lighting Contactor

The 8903LXO40V02 lighting contactor is built for straightforward, reliable control of large lighting loads. It’s commonly used in commercial and industrial setups where lights need to switch on and off consistently without putting extra demand on the system. With a 30A rating for fluorescent lighting and 20A for tungsten, this 4-pole unit handles typical lighting circuits with ease.

What sets this model apart is its mechanically held design. Once the contactor changes state, it stays there without continuous power to the coil. In day-to-day operation, that can help cut down on energy use and reduce wear on the control circuit. It uses two coils—one to latch and one to unlatch—running on standard 110/120 VAC (50/60 Hz), so it fits into most existing control setups without much trouble.

It’s also built with serviceability in mind. The contacts can be changed from normally open to normally closed in the field, and both coils and contacts are replaceable. The open-style design makes it easy to install in a panel or enclosure that fits your setup, and the screw-clamp terminals keep wiring simple and secure.
