Square D NQ472L2C NQ Panelboard Interior, 225A, 3 Phase, 72 Pole Spaces, 240V AC, Copper Bus

Description

Features

• Engineered with an industry-leading 72 pole spaces, this electrical panelboard interior provides massive circuit density within a standard 44-inch NEMA enclosure footprint. This extensive circuit layout ensures commercial contractors and facility managers have plenty of expansion room for dense lighting, appliance, and branch distribution networks without needing to buy a second, costly panel enclosure.
• Featuring a high-conductivity solid copper bus assembly, this interior minimizes heat generation and limits voltage drops across heavy-duty runs. The robust copper construction ensures long-term operational reliability in demanding environments and completely bypasses the thermal expansion issues or routine torque inspections associated with cheaper aluminum alternatives.
• This NQ series interior is precision-machined to accept Square D QOB bolt-on, QOB-VH high-interrupt, and QHB heavy-duty branch circuit breakers. The physical bolt-on configuration provides a secure mechanical connection to the copper bus, eliminating vibration-induced loose contacts and ensuring maximum safety in commercial or industrial settings.
• Built to handle demanding 3-phase, 4-wire systems up to 240 VAC or 48 VDC, this interior seamlessly integrates with systems requiring 200% rated neutral setups to manage harmonic distortion. This heavy-duty current management safely mitigates transformer neutral overheating caused by extensive LED lighting arrays, variable frequency drives (VFDs), and modern office IT equipment.
