Eaton PRL4X3190B18C2S Panelboard - UL 67, 1200A 3-Phase
Part Number: PRL4X3190B18C2S
Quick Summary
Pow-R-Xpress PRL4X panelboard delivers reliable, high-capacity power distribution for electrical subsystems in commercial and light industrial facilities. Engineers often struggle with space constraints, retrofit challenges, and staying compliant during panel upgrades. UL 67 certification ensures safe operation of interior panelboards in demanding environments, while the three-phase design and copper bus support high fault withstand and efficient distribution. This interior assembly is optimized for top-feed installation, enabling faster wiring and reduced field labor. By aligning with the Pow-R-Xpress stocking program, you can simplify procurement, shorten lead times, and standardize a scalable solution across multiple projects. For ongoing maintenance, the rugged construction and clear labeling help technicians diagnose and expand capacity without costly downtime. The result is a reliable, future-ready panelboard that fits growing energy needs and tight schedules.

FAQs
Yes, the PRL4X3190B18C2S is designed as an interior Pow-R-Xpress panelboard suitable for 480/277V, 3‑phase systems with top-feed access. Its footprint aligns with standard commercial/industrial installations, and the 68.75 in length, 22 in width, and 8 in height provide a consistent cabinet depth for retrofit or new-build projects. When integrating with existing gear, verify feeder accommodations and MCB compatibility (PD5 PXR20 blocks) to ensure seamless upgrade paths.
Core specs include a 1200A amperage rating, 480/277V operation, three-phase configuration, copper bus, and UL 67 listing. These features support high-current loads with robust fault withstand, enabling efficient distribution across large facilities. The design also facilitates organized subfeeds (up to 18 circuits) and top-feed wiring, which enhances circuit protection alignment and reduces voltage drop in long feeder runs.
The PRL4X interior panelboard is well suited for commercial buildings, manufacturing floors, data centers, and campus-type facilities requiring reliable 3‑phase power distribution at high capacity. Its rugged copper bus and interior assembly support dense feeder layouts, while its size and weight are optimized for fixed installations in dedicated electrical rooms or cabinets.
This panelboard is UL 67 listed, confirming compliance with safety standards for interior electrical panelboards. UL 67 certification helps satisfy regulatory requirements for commercial and industrial spaces, supports risk mitigation for short circuits and arc events, and simplifies inspection and qualification processes during both new installations and retrofit work.
The Pow-R-Xpress program offers faster availability and standardized parts across sites, reducing lead times and procurement costs. With components designed for straightforward wiring and maintenance, technicians spend less time on commissioning and more on productive tasks. Over the life of a facility, this translates to lower downtime, easier future expansions, and a stronger total cost of ownership.
