Pow-R-Line Xpert family overview
Neutral termination design supports wide conductor ranges, minimizing torque variability and termination errors. This improves long-term connection reliability under thermal cycling and load transients, especially in compact panel enclosures. It applies directly to PRL4X neutral integration in Eaton Pow-R-Xpress panelboards, streamlining field wiring. UL 67 certification and NEMA compliance ensure code-aligned performance, reducing inspection time and boosting safety margins in critical installations. The robust ROH material combined with an aluminum bus delivers corrosion resistance and mechanical strength without adding unnecessary bulk, supporting dependable operation in harsh environments. Its compact footprint — 8.142 in long with a 0.625 in profile and 0.375 in width — frees valuable space in crowded panels while preserving electrical integrity. Compatibility with #14-#6 and #14-1/0 conductors enables straightforward design integration for both retrofit and new-build projects. Used with PRL4X NEUTRAL, this terminal bar is a turnkey solution that minimizes BOM complexity and accelerates commissioning. Despite its slim profile, the unit maintains reliable contact performance under vibration and temperature swings, addressing common objections about space-constrained panelboards with a proven, field-tested design. The combination of aluminum bus, ROH construction, and a dedicated modular interface supports consistent electrical performance, lower maintenance intervals, and a clearer path to regulatory compliance across diverse industrial applications.

FAQs
The P4NLTERMBAR is designed specifically for use with the PRL4X neutral module in Eaton Pow-R-Xpress panelboards. It accepts a wide conductor range including #14-#6 and #14-1/0 conductors, enabling straightforward retrofits or new builds. The aluminum bus and ROH-compliant construction provide robust mechanical strength, while the compact footprint eases mounting in dense panel environments. When integrating, ensure the neutral path aligns with the PRL4X module and that conductor sizes match the terminal bar’s supported range, to maintain proper torque and termination integrity over the system life.
The P4NLTERMBAR supports conductor ranges from #14 to #6 and from #14 to 1/0, covering common branch feeder and neutral connections in Pow-R-Xpress panelboards. This broad compatibility enables flexible wiring strategies, reduces the need for additional adapters, and simplifies BOM planning. The terminal bar’s design ensures consistent seating and termination reliability across these conductor sizes, even under thermal cycling and vibration found in industrial environments.
Yes. The P4NLTERMBAR carries UL 67 certification and is designed to be NEMA compliant, which aligns with typical safety and performance requirements for panelboard components in commercial and industrial settings. These certifications support compliance during inspections and commissioning, reduce uncertainty in procurement, and help ensure long-term reliability of neutral terminations in Power-R-Xpress configurations.
The terminal bar measures 8.142 inches in length, with a height of 0.625 inches and a width of 0.375 inches, and weighs about 1 pound. This compact, lightweight form factor enables easier installation in space-constrained panels, supports modular mounting with PRL4X, and minimizes added panel depth. The slim profile reduces clearance concerns and helps maintain adequate room for bus bars and feeders in dense electrical gear.
The P4NLTERMBAR uses ROH material with an aluminum bus, delivering corrosion resistance and robust mechanical strength. This combination supports durable performance in varied environments while helping align with RoHS and environmental safety expectations. UL 67 certification and NEMA compliance further reinforce reliability and regulatory alignment, enabling safer operations, lower maintenance needs, and clearer paths to regulatory audits in industrial facilities.
