8903SQO10V02 - Square D Lighting Contactor
The 8903SQO10V02 lighting contactor is a straightforward solution for controlling lighting in commercial and industrial setups. It’s mechanically held, so it doesn’t draw power continuously—only when switching. That’s a practical advantage if you’re trying to cut down on energy use or avoid unnecessary heat in your panel.
With a 100-amp rating and a 2-pole configuration, it’s built to handle typical lighting loads you’d find in larger buildings, warehouses, or exterior lighting systems. It comes with a 110/120VAC coil, which covers most standard applications, and since the coil is interchangeable, you’re not locked into one setup.
The open-style design keeps things simple. You can mount it as-is or pair it with the enclosure that makes sense for your environment. No extras you don’t need—just a dependable contactor that does what it’s supposed to do.
