Square D 8903SPG2 Three Phase Lighting Contactor

Square D by Schneider Electric 8903SPG2 is a three-pole lighting contactor designed to control large lighting loads in commercial and industrial settings. It is rated to switch up to 60 A on circuits up to 600 VAC, making it suitable for multi-lamp fixtures or three‑phase lighting circuits in a single enclosure. The V02C coil variant uses a 120 VAC control signal at 50/60 Hz to energize and hold the contactor, providing a reliable latch until de-energized. This electrically held design helps reduce control wiring requirements in standard lighting control schemes. The unit ships in a NEMA 1 enclosure, meaning it is intended for indoor, dry environments and offers basic dust and incidental moisture protection typical of indoor electrical equipment. The 8903SPG2 family is a part of Square D’s Type S multipole lighting contactors, with three poles and a robust switching pathway suitable for commercial lighting coils and distribution. This model is documented as UL listed and CSA certified for use in appropriate electrical installations, and is commonly used where a dedicated contactor is required to switch three separate lighting circuits or a three‑phase lighting load. When replacing or retrofitting, ensure coil voltage (120 VAC, 50/60 Hz) matches the control circuit and confirm that the maximum load current and line voltage meet your application requirements.
