Description

NF Panelboard Interior 400A 54 Spaces 3 Phase 4 Wire 600Y/347 VAC

Features

Engineered with 54 pole spaces, this 400A panelboard interior allows for extensive high-density circuit routing in commercial and industrial buildings. The high space count provides the headroom needed to accommodate future layout expansions or additions without requiring an expensive secondary panel enclosure swap.
This rugged interior safely supports heavy power distribution systems up to 600Y/347V AC (and standard 480Y/277V AC) across a three-phase, four-wire configuration. Designed for intense environments like factories, data centers, and offices, it safely manages heavy-duty motor, lighting, and HVAC machinery loads.
Built as a Main Lug Only (MLO) configuration, the interior features field-convertible modular construction that seamlessly transitions from top to bottom feed or to a main circuit breaker with a simple kit. This flexible architecture eliminates long lead times and restocking fees if a project changes from main lugs to back-fed main protection mid-installation.
The plated aluminum busbar assembly is engineered specifically to accept Square D bolt-on branch circuit breakers including EDB, EDG, and EJB series. Choosing this verified factory setup eliminates mechanical fitment errors, ensures code-compliant electrical connections, and delivers an interrupt rating of up to 65kA to safely handle severe high-fault currents.
The factory-installed mechanical main lugs accept large-gauge copper or aluminum line and neutral wiring spanning from 1/0 AWG up to 750 kcmil. This massive terminal window allows commercial contractors to use heavier, cost-effective aluminum wiring or high-conductivity copper without buying aftermarket mechanical lug kits.
