Schneider Electric Square D NF442L2 Panelboard

Schneider Electric's Square D NF442L2 Panelboard Interior is a 42-space NF-series panelboard interior with main‑lug access, rated for 250 A and configured with aluminum bus. It supports three‑phase, four‑wire systems and is compatible with a maximum of 600Y/347 VAC, making it suitable for commercial or light industrial power‑distribution environments that use 347 VAC three‑phase services. The NF442L2 interior provides 42 spaces for circuit‑breaker devices, enabling substantial branch‑circuit deployment within a proper Square D enclosure. Because this interior uses main‑lugs rather than an integral main breaker, incoming feeders terminate at the lugs, and any required main protection must be provided by a separate main breaker or main‑lug assembly within the overall panel configuration. This interior is intended to be paired with NF‑series enclosures and the NF panelboard devices specified by Schneider Electric for NF panelboards, to form a complete distribution panel. In installations needing a 250 A service with a high circuit count, the NF442L2 offers a compact footprint and scalable layout that can accommodate a range of circuit‑breaker layouts while maintaining standard Square D NF design conventions.
