Schneider Electric NQ3642400A3P4W0 Panelboard

Schneider Electric's Square D NQ3642400A3P4W0 Panelboard is a 400 A, three-phase, four-wire distribution panel from the NQ family, configured for 208Y/120 VAC service. It offers 42 spaces for circuit breakers, delivering substantial capacity for organizing and protecting a broad range of loads in commercial or light-industrial facilities. This panelboard uses the NQ interior framework designed to accept Square D breakers and provides three hot legs plus a neutral, supporting orderly load distribution and clear circuit segregation. The model encoding identifies a 400 A rating, a 3-pole, 4-wire configuration, and a 42-space interior—attributes that align with large-capacity installations commonly found in electrical rooms, data centers, and multi-tenant commercial buildings. Built for reliable power distribution, it enables scalable expansion as electrical demand grows while maintaining coordinated protection across circuits.
