Pow-R-Line Xpert family overview
800A amperage rating enables a single panelboard to feed large loads, reducing the number of devices needed and lowering installation time. This translates to improved reliability and maintenance efficiency in 480/277V three-phase systems across manufacturing lines and facilities. Thirty circuits offer expanded capacity for future expansion within a single enclosure. For OEMs and integrators, this reduces panel count in the field and simplifies wiring logistics during plant upgrades. Bottom-feed configuration simplifies enclosure layout during retrofits and new installs, enabling cleaner wiring runs and faster field assembly in crowded electrical rooms. Copper bus delivers low resistance and high current-carrying capability, supporting thermal stability and long-term performance in harsh industrial settings. UL 67 listing confirms safety compliance for interior panelboards, helping installers meet code requirements quickly and confidently. This performance profile suits healthcare, data centers, and manufacturing environments that demand dependable power distribution and tight installation schedules. The interior assembly design facilitates faster maintenance and modular upgrades, reducing downtime during panel refurbishment and allowing easier integration with modern monitoring and control architectures. For system integrators, the PRL4X3873BB0C2S aligns with standard Eaton Pow-R-Xpress accessories, enabling plug-and-play expansion and consistent electrical design language across facilities.
