Schneider Electric's Square D 8903-SPG11-CF4T Contactor Enclosure is an enclosure designed to house a Square D 8903-series lighting contactor (the 8903-SPG11-CF4T model ships without a contactor). The SPG11 designation identifies this unit as part of Schneider Electric's SPG family of NEMA 1 general-purpose enclosures, intended for indoor control‑panel installations with contactors in the 8903 lineup. Retail listings for 8903-SPG11-CF4T explicitly note "NO Contactor," confirming that the package includes only the enclosure.
