Description
NQ Panelboards are versatile panelboards that feature a wide selection of circuit breakers, accessories, and ready to install kits. NQ Panelboards provide 2% rated neutrals for non-linear loads. NQ Panelboards are convertible from main lug to main breaker. This NQ Panelboard interior has a main lug and is rated at 4 A and 3 phases. With 4 wire system with 72 circuits and aluminum busbar, these interiors provide protection for your commercial and industrial applications. NQ Panelboard interiors are field convertible to top or bottom feed. Some factory installed options are split bus, lighting contactors, compression lugs, surge protection devices, and phenolic nameplates. NQ Panelboard interiors can be used for applications such as commercial buildings, industrial buildings, stadiums, and offices. 1P-short-circuit current 10 kA-Range Presentation Some factory installed options are split bus, lighting contactors, compression lugs, surge protection devices, and phenolic nameplates. Interior is 57 inches tall and 10.44 inches wide. Lug connections will accept 1/0 AWG to 750 kcmil aluminum wire. This interior is UL listed and CSA certified. NQ Panelboard interiors can be used for applications such as commercial buildings, industrial buildings, stadiums, and offices.
Features
- Featuring an extra-high density, 72-circuit layout, this panelboard interior maximizes distribution capacity within a standard enclosure footprint. It allows commercial electricians and plant engineers to consolidate multiple sub-panels into one central location, accommodating a massive array of single-, double-, or three-pole breakers to easily handle future tenant fit-outs, machinery additions, or automated lighting upgrades.
- Engineered with robust, high-conductivity copper buses rated for a full 400 Amps at 240V AC, this interior delivers reliable primary or secondary power distribution for high-demand electrical environments. The heavy-duty 400A busing mitigates heat buildup and voltage drop under continuous peak loads, making it ideal for large offices, retail spaces, and modern manufacturing facilities.
- Engineered for ultimate versatility, the chassis seamlessly accepts both standard Square D™ QO™ plug-on breakers and QOB bolt-on circuit breakers. This dual compatibility allows contractors to meet rigid project specifications—such as utilizing high-vibration resistant bolt-on breakers for industrial machinery while dropping in cost-effective plug-on components for standard commercial lighting circuits—greatly simplifying on-site inventory management.
- Shipped out of the box with a 400-amp, 3-phase, 4-wire main lug configuration, this interior easily converts into a main circuit breaker panelboard using simple, field-installable conversion kits. This agile design allows you to quickly adapt to shifting design-build requirements on the job site or seamlessly upgrade sub-panels to primary service entrance equipment without scrapping the original core hardware.
