Description
NQ Panelboard Interior, 400A, 72 Circuits, 4-Wire, 240V AC, Aluminum
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 DTM QOTM 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.
