Eaton PRL4X3873B00C1S Panelboard - UL 67, 800A
Part Number: PRL4X3873B00C1S
Quick Summary
Eaton Pow-R-Xpress PRL4X panelboard is a high-capacity power distribution solution designed for industrial facilities. For engineers and maintenance teams, wiring complexity and long lead times are common pain points that slow projects and raise costs; this panel consolidates feeders and simplifies service during upgrades. UL 67 certification and a NEMA 1 enclosure provide safety and indoor protection, while the three-phase copper bus delivers reliability in demanding environments. With 208/120V operation and an 800A rating, PRL4X3873B00C1S scales to growing electrical demands, and its Pow-R-Xpress compatibility supports faster stocking and installation, reducing downtime and total cost of ownership.

FAQs
The PRL4X3873B00C1S is a top-feed interior panelboard designed for indoor installations. Plan for a 50.25 inch length, 22 inch width, and 8 inch height footprint, with a 350 lb weight. Ensure adequate clearance for service access, allow for copper conductor terminations up to (2) 500-750 kcmil, and verify 208/120V three-phase compatibility with downstream equipment.
This panelboard accepts (2) 500-750 kcmil conductors, enabling large feeder connections with low resistance. Proper termination requires caliper-compatible lugs and torque procedures per UL 67 guidelines. The copper bus construction improves conductivity and reduces voltage drop, supporting reliable operation of high-current loads up to 800A.
Yes, the PRL4X3873B00C1S carries UL 67 certification, aligning with standard safety requirements for panelboards. It is configured with a NEMA 1 enclosure, suitable for indoor, dry environments where protection against dust and incidental contact is needed.
Ideal for industrial facilities with substantial power needs, including manufacturing lines, data centers, and process plants. Its 800A rating and three-phase design support large motor loads and equipment feeds, while its compact interior assembly enables easier integration in space-constrained rooms.
The interior PRL4X3873B00C1S simplifies field service with accessible terminations and a robust copper bus path, reducing maintenance time. Its UL 67/NEMA 1 compliance lowers regulatory risk, while higher efficiency and reduced wiring complexity contribute to lower total cost of ownership over the system’s life cycle.
