Description
NQ Panelboards are versatile panelboards that feature a wide selection of circuit breakers, accessories, and ready to install kits. NQ Panelboards provide 200% rated neutrals for nonlinear loads. NQ Panelboards are convertible from main lug to main breaker. Interior has a maximum voltage rating of 240 VAC and 48 VDC. This NQ Panelboard interior has a main lug and is rated at 225 A three phase. Interior has an interrupt current rating of up to 65 kA. This interior is for a 4 wire system with 72 circuits and has an aluminum bus bar. Interior is for QOB, QOBVH and QHB branch circuit breakers. This interior provides 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. Lug connections will accept 6 AWG to 350 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 a high-density, 72-circuit layout, this panelboard interior maximizes available space within a standard footprint, allowing commercial electricians and facility engineers to consolidate distribution. It accommodates a vast array of single-, double-, or three-pole breakers, ensuring your infrastructure is fully prepared for tenant fit-outs, machinery additions, and unexpected electrical load expansions without requiring a costly second panel enclosure.
- Engineered for ultimate versatility, the chassis 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 225-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 hardwar
- Built with a fully symmetrical chassis design, this interior can be flipped in the field to support either top or bottom cable incoming feeds. This eliminates installation bottlenecks and matching design errors, enabling field technicians to rout incoming 240V AC or 48V DC feeder lines naturally based on existing structural building layouts and conduit path
- Engineered to seamlessly integrate with 200% rated neutral accessory kits, this interior is purpose-built to mitigate excessive neutral bus overheating caused by non-linear electronic loads. This essential feature safeguards sensitive commercial data centers, LED lighting arrays, and office server rooms from catastrophic harmonic feedback failures and tracking fires, keeping operations code-compliant and safely online.
