Description
NQ Panelboard interiors may be used in a wide variety of applications including: commercial buildings; industrial buildings; data centers; stadiums; and offices. NQ Panelboards are versatile panelboards that feature a wide selection of bolt-on and plug-on branch circuit breakers, integral main circuit breakers, branch mounted SPDs, and a wide variety of ready to install accessory kits. The interiors are field convertible to support top or bottom feed. NQ Panelboards are convertible from main lugs to main circuit breaker. NQ 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. NQ 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 NQ panelboard interior is UL listed for applications in the USA and Canada. Interior accepts QOB, QOBVH and QHB bolt-on and QO, QOVH and QH plug-on branch circuit breakers. Standard mechanical main lug connections will accept copper or aluminum wire. NQ Panelboard interiors are available with plated aluminum or copper bus. 100A branch circuit breakers may be installed on both sides of NQ Panelboard interiors. This NQ panelboard interior is UL listed and CSA certified.
