Panelboard Interior, NF, Main Lugs, 400A, CU Bus, 42 Spaces, 3PH, 4W, 480Y/277VAC

NF Panelboard interiors may be used in a wide variety of applications including: commercial buildings; industrial buildings; data centers; stadiums; and offices. NF Panelboards are versatile panelboards that feature a wide selection of bolt-on branch circuit breakers, integral main circuit breakers, bus mounted SPDs, and a wide variety of ready to install accessory kits. NF Panelboard interiors are field convertible to support top or bottom feed. This main lugs interior is rated 400A for 600Y/347VAC, has a plated copper bus, and 42 pole spaces. NF Panelboards are convertible from main lugs to main circuit breaker. NF Panelboards offer 200% rated neutrals for nonlinear loads. Factory installed options include phenolic nameplates, power monitoring of mains and branch circuits, split bus interiors, and neutral assemblies which support up to 36 100A branch circuit breakers. NF Panelboards are available with IP2X per IEC 60529 barriers for UL service entrance applications. Interior has an interrupt current rating of up to 65kA (depending upon the circuit breakers installed). This NF panelboard interior is UL listed for applications in the USA and Canada. Interior accepts ECB, EDB, EGB, and EJB bolt-on branch circuit breakers. Standard mechanical main lug connections will accept copper or aluminum wire. Kits available to replace standard main mechanical lugs with compression lugs, sub-feed lugs, or a vertically mounted main circuit breaker. NF Panelboard interiors are available with plated aluminum or copper bus. Standard 100% rated neutrals accept aluminum and copper wire; field installable kits support 200% rated or copper neutral assembly requirements. NF Panelboards may be used in voltage systems up to 600Y/347VAC.
