Schneider Electric QGL22150 Panelboard Interior

Schneider Electric's Square D QGL22150 Panelboard Interior is the 30-space interior assembly for a Square D NQ panelboard, rated for 400 A at 208Y/120 V, 3-phase, 4-wire. This interior serves as the distribution core inside NQ panelboard enclosures, providing the mounting points for branch-circuit breakers and the necessary bus structure to support a mid-size electrical distribution in commercial or light-industrial environments. With 30 available spaces, the QGL22150 interior supports up to 30 circuit positions within a 400 A, 208Y/120 V system, enabling organized, scalable protection and control for loads such as lighting, outlets, and equipment circuits when paired with compatible Square D breakers and enclosure components. Cataloged as QGL22150, this interior aligns with 30-space, 400 A NQ panelboard configurations in the Square D product family, making it a practical choice for projects that require upgrading service capacity or reorganizing distribution. Typical applications include office buildings, retail spaces, and light industrial facilities where a 400 A, 208Y/120 V distribution panel is appropriate.
