Eaton PRL3X3490B00C1 Pow-R-Xpress panelboard - UL 67
Part Number: PRL3X3490B00C1
Quick Summary
The Eaton PRL3X3490B00C1 Pow-R-Xpress panelboard is a compact, UL 67-rated power distribution solution for commercial and light industrial electrical rooms. Engineers often contend with tight spaces, cumbersome wiring, and long cabinet workflows when upgrading panel capacity. UL 67 and NEMA compliance underpin reliability in critical environments, while its three-phase 400 A rating supports scalable loads and future expansion. Designed to integrate with the Pow-R-Xpress family, it offers predictable installation timelines, consistent electrical performance, and clear code compliance. For procurement teams, the copper bus construction, top-feed configuration, and documented reference guides help reduce risk, minimize downtime, and lower total cost of ownership over the project lifecycle.

Pow-R-Line Xpert family overview
Feature 1: 400A amperage rating and 208/120V three-phase configuration provide the capability to distribute substantial loads with balanced phases. Business Impact: Enables scalable electrical distribution for growing facilities while maintaining voltage integrity and protection coordination. Application: Main distribution in commercial spaces and light industrial rooms where space is at a premium. Feature 2: Copper bus material and robust copper construction reduce resistance, improve conductivity, and enhance long-term reliability. Business Impact: Lower I²R losses and longer service life translate to lower operating costs and fewer maintenance events. Application: High-demand feeder runs and critical circuits in data centers and manufacturing environments. Feature 3: Top feed and interior assembly simplify wiring access and cabling management. Business Impact: Reduces installation time and labor risk during retrofit projects or new builds. Application: Retrofit projects in existing electrical rooms with limited space. Feature 4: UL 67 certification and NEMA compliance provide proven safety and regulatory alignment. Business Impact: Streamlines code approvals and reduces the risk of non-compliance penalties. Application: Emergency and standard power distribution in regulated facilities. Feature 5: Physical footprint and weight specifications (78 in length, 12 in width, 5.75 in height; 120 lb) support planful space allocation. Business Impact: Accurate space planning and easier handling during installation. Application: Facility upgrades and new builds using the Pow-R-Xpress family. Feature 6: Documentation and quick selector resources expand procurement efficiency. Business Impact: Accelerates design cycles and reduces engineering turnaround time. Application: Specification and purchasing workflows in engineering firms and electrical contracting.

FAQs
To maximize compatibility, confirm the interior configuration matches the existing Pow-R-Xpress family and maintain top-feed wiring as designed. Ensure mounting clearance for the 78 in length and the 120 lb weight, and reference Eaton's quick selector guides for correct bus and breaker arrangements. This minimizes field changes and preserves system integrity.
The PRL3X3490B00C1 operates at 208/120V, three-phase, four-wire, with a 400A amperage rating. It carries UL 67 certification and NEMA compliance, and uses copper bus for lower resistance. These specs support robust distribution in commercial and light industrial environments while meeting code requirements.
Yes. UL 67 certification and NEMA compliance support reliable operation in emergency and life-safety lighting applications. The 400A three-phase design enables essential loads to be prioritized, while the copper bus ensures consistent performance under fault conditions and during peak demand.
Top-feed configuration reduces wiring complexity at the cabinet top, streamlines conductor routing, and shortens assembly time. Combined with a 78 inch long interior and integrated copper bus, installers benefit from faster sheet-to-finish timelines and lower labor costs on retrofit or new-build projects.
Eaton provides quick selector reference guides and program brochures specific to Pow-R-Xpress products. These resources help engineers select the correct interior configuration, verify compatibility, and accelerate procurement, reducing design risk and speeding project timelines.
