Eaton PRL2X3400B42A1 Panelboard Interior - UL 67
Part Number: PRL2X3400B42A1
Quick Summary
The Eaton PRL2X3400B42A1 panelboard interior distributes power reliably for industrial control panels. Design and installation challenges like wiring density, space constraints, and safety risk are common. UL 67 certification, aluminum bus construction, and a 400 A rating reinforce reliability and code compliance. This interior panelboard is designed for fast, scalable installations in 120/208 V three‑phase four‑wire systems. By combining factory-installed MCBs with Pow-R-Xpress stock support, it delivers time savings and predictable performance. Engineers benefit from clear wiring plans, reduced field labor, and improved maintenance planning. Its aluminum bus and 72-inch length enable scalable layouts for growing facilities while maintaining compact enclosure footprints.

FAQs
The PRL2X3400B42A1 interior panelboard is designed for industrial control panels operating at 120/208 V in three‑phase four‑wire systems. Its 400 A rating and 42 circuit capacity make it ideal for manufacturing lines, facility distribution, and automation racks where space is at a premium and reliable protection is required.
The panelboard interior carries UL 67 certification, ensuring compliance with safety standards for panelboards. This listing supports safe integration into commercial and industrial electrical distributions and simplifies inspection and commissioning processes.
The unit offers a 72 inch length, 8 inch width, and 4.25 inch height, with an approximate weight of 51 pounds. These dimensions facilitate ample wiring space while fitting within typical control room enclosures and panel housings.
Aluminum bus bars reduce overall panel weight, ease field handling, and resist corrosion in service environments. This translates to simpler installation, lower labor costs during wiring, and long-term durability in automated facilities with frequent access to the interior.
Factory-installed MCBs and SFB on a 42‑circuit interior minimize on‑site assembly, while Pow-R-Xpress compatibility helps with rapid procurement and lead-time reduction. Together, they shorten commissioning cycles and improve project ROI by delivering a ready-to-wire panelboard straight from stock.
