Eaton PRXP31PFILLER Panelboard Filler - UL 67
Part Number: PRXP31PFILLER
Quick Summary
PRXP31PFILLER is a panelboard filler used in Eaton Pow-R-Xpress PRL3X installations to preserve enclosure integrity. Engineers often struggle with gaps, dust ingress, and retrofit challenges when filling unused spaces in compact panelboards. This filler meets UL 67 certification and NEMA compliance, helping you satisfy electrical safety and enclosure standards. Designed for snap-in compatibility with PRL3X sub chasses and tight tolerances, it minimizes gaps without specialized tools, supporting faster commissioning and higher uptime in electrical rooms. For integrators and maintenance teams, the slight additional cost is offset by improved safety, easier inventory management, and reduced warranty concerns. Its lightweight steel construction also aids handling and resale value for field service operations.

Pow-R-Line Xpert family overview
UL 67 certification and NEMA compliance are built into the PRXP31PFILLER. This compliance translates to safer enclosures and audit-ready documentation, reducing risk during inspections and installations across commercial and industrial facilities. In practice, you can deploy this filler with confidence in low-voltage panelboards that demand strict safety standards. Durability comes from a steel construction that resists impact and dust ingress, delivering long-term reliability in harsh environments found in manufacturing floors and electrical rooms. The 1P filler minimizes deformation under normal service and supports consistent performance across Pow-R-Xpress panels, reducing field repairs and extending service life. Snap-in compatibility with PRL3X sub chasses enables tool-free installation and quick reconfiguration, which is especially valuable during plant start-ups or retrofit projects. The precise fit minimizes gaps and maintains enclosure seals, improving overall protection. Its compact dimensions and light weight simplify handling and inventory management for field crews, reducing labor costs and freight footprint while avoiding crowding in tight spaces. Standardizing on 1P fillers like PRXP31PFILLER streamlines spare parts catalogs and service workflows, delivering predictable project outcomes and scalable deployment across multiple panelboards.

FAQs
PRXP31PFILLER is a steel, 1P filler designed for Eaton Pow-R-Xpress PRL3X panelboards. It fills unused 1-pole spaces in the low-voltage enclosure to preserve enclosure integrity and dust protection. Its dimensions are 2.483 in long, 0.312 in high, and 1 in wide, with an approximate weight of 0.2 lb. It installs in compatible PRL3X configurations.
The part carries UL 67 certification and is NEMA compliant. UL 67 covers electrical panelboards, while NEMA compliance ensures compatibility with standard enclosures used in commercial, industrial, and process environments. Together, these certifications simplify regulatory reporting, reduce audit findings, and support warranty coverage for assembled Eaton panel systems.
Yes. PRXP31PFILLER is engineered for snap-in compatibility with PRL3X sub chasses, allowing tool-free installation and quick reconfiguration. The precise steel filler minimizes gaps and maintains enclosure seals, which is especially valuable during plant starts or expansions. Proper alignment with the PRL3X modules helps ensure consistent performance across panels.
Using the filler reduces commissioning time by eliminating the need for custom cutouts and reduces field errors from improper gaps. It strengthens dust protection and mechanical integrity, improving uptime in manufacturing and facilities operations. For project teams, standardizing on 1P fillers like PRXP31PFILLER also streamlines spare parts and service workflows.
From a compliance and maintenance perspective, adopting UL 67 and NEMA-compliant fillers supports safer, audit-ready panel assemblies. The sturdy steel construction withstands routine handling, while the tool-free installation lowers labor costs during retrofits. Over a project lifecycle, these factors contribute to lower total cost of ownership and more predictable ROI for industrial distributors and end users.
