Schneider Electric NF125A42S3W480Y277V Panelboard

Schneider Electric's NF125A42S3W480Y277V panelboard is a 125 A NF lighting and appliance panelboard configured as a 42-space, 3‑phase, 4‑wire interior designed to distribute 480Y/277 V services across commercial circuits. This model uses a Type W indoor enclosure and is main-lug-only (MLO), meaning there is no factory-installed main breaker and all circuit protection is provided by branch devices mounted on the interior bus, with 42 usable spaces for expansion or subfeed arrangements. This arrangement is commonly used in commercial installations where a separate upstream main disconnect exists, or where subfeed distribution within a larger electrical system is required, offering organized circuit planning in a relatively compact footprint. For dry indoor environments such as offices, retail spaces, healthcare facilities, and other commercial settings, the NF125A42S3W480Y277V provides a robust 125 A rating and a 42-pole layout that supports 480Y/277 V distribution using NF-series breakers and accessories from Schneider Electric.
