Eaton PRL4X3190B18C1 Panelboard - UL 67 Cert
Part Number: PRL4X3190B18C1
Quick Summary
The Eaton PRL4X3190B18C1 panelboard is a high-capacity interior power distribution unit designed for 208/120V three-phase service, making it ideal for large commercial facilities, industrial plants, and data centers that demand reliable feeders. Facilities struggle with crowded switchgear and upgrades that disrupt production; this interior panelboard optimizes space with a 68.75 in depth, 22 in width, and 8 in height, while delivering 72 circuits and a 1200A rating to support future expansion. UL 67 certification ensures safe interior assemblies, and copper bus provides reliable, low-resistance current transfer under heavy loads. As a Pow-R-Xpress interior solution, it enables faster installation, modular expansion, and predictable maintenance budgets, helping engineering teams meet project timelines and operators achieve higher uptime and lower lifecycle costs.

Pow-R-Line Xpert family overview
High amperage rating of 1200A enables large feeders and reduces panel sprawl, improving efficiency and space utilization in manufacturing floors. Copper bus and top feed create a low-impedance path, delivering stable voltage under peak demand and simplifying wiring during installation. With 72 circuits spread across three phases, the PRL4X3190B18C1 supports scalable distribution for expanding facilities and heavy-duty equipment. UL 67 certification provides regulatory assurance and reduces compliance risk, while the rugged copper construction improves longevity in harsh environments. The large footprint, measured at 68.75 in length, 22 in wide, and 8 in high, accommodates bundled conductors and subfeed connections with room for future growth. Compatibility with PD5 PXR20 ALSI 18CKT SUBCHS enables straightforward retrofits and modular expansion, lowering total cost of ownership over time.

FAQs
The interior panelboard uses a top-feed configuration and copper bus to connect 1200A feeders cleanly. It supports 72 circuits and aligns with PD5 PXR20 ALSI 18CKT SUBCHS for modular expansion, simplifying retrofit projects in industrial facilities and data centers.
With a 1200A amperage rating and copper bus, the unit provides low impedance pathways for stable voltages under peak demand. UL 67 certification confirms compliance, while the interior design minimizes resistance and heat buildup in heavy-use environments.
Yes. Its 68.75 in length, 22 in width, and 8 in height support dense conductor layouts; 72 circuits across three phases meet demanding distribution needs, and compatibility with ALSI sub-chassis enables rapid scaling for growing facilities.
UL 67 certification covers interior panelboard assemblies, ensuring safe construction, insulation, and enclosure integrity in industrial environments; copper bus material further supports compliance and longevity.
The modular design, top-feed access, and compatible subchassis reduce installation time and spare-part costs, lowering total cost of ownership while improving uptime in mission-critical applications.
