Schneider Electric 8903 PO-2 Lighting Contactor

Schneider Electric's Square D 8903 lighting contactor, PO‑2, is a two‑pole, open‑style device designed to switch lighting loads in commercial control systems. It is rated for 60 A and uses a coil rated for 120/110 VAC at 60/50 Hz, making it compatible with common North American and many international lighting control circuits. As part of the 8903 family, this contactor is built to handle typical lighting applications such as large banks of interior or exterior lights, signage, and other building illumination circuits where a reliable, mechanically simple on/off switch is required. The open‑type enclosure supports installation in control panels or remote enclosures, and the two poles provide the necessary switching for single‑phase lighting or paired circuits as your layout demands. When selecting a PO‑2 variant, ensure coil voltage matches the control circuit and confirm mounting footprint and terminal configuration against the factory datasheet for a precise fit in your control panel. This Square D/Schneider Electric product reflects the brand’s long‑standing approach to robust lighting control components used in industrial and commercial electrical installations.
