Schneider Electric NQ3642 Panelboard

Schneider Electric's Square D NQ3642 panelboard is a 400 A, three-phase, four-wire distribution panel with 42 spaces, configured for 208Y/120 VAC service and delivered in a complete 3R enclosure. As part of Schneider Electric's NQ panelboard family, the NQ3642 interior is designed for 400 A applications and supports a full complement of branch breakers across 42 circuit spaces. Schneider Electric also offers factory-assembled interiors within the NQ lineup, enabling ready-to-install configurations for 400 A configurations and simplifying ordering for 42-space, 3P4W systems. This combination—400 A main and 42 spaces—provides a scalable solution for distributing power to downstream circuits while maintaining a single, code-compliant panel in a 3R enclosure.
