Three-pole, F-frame Pow-R-Way III plug-in unit delivers robust overcurrent protection for busway installations. The 80A rating paired with 18 kAIC at 240V minimizes fault energy and guards critical equipment, reducing unplanned downtime. It’s ideal for use in modular busway configurations across manufacturing lines and distribution centers. Grounding options include 50% integral/housing grounding, simplifying installation and improving safety by providing a reliable earth path without complex field wiring, which reduces wiring effort in panelless or partially enclosed busways. Plug-in design enables fast field replacement and reduced downtime during maintenance or upgrades, since units can be swapped quickly without bespoke assembly. Compliance and certifications—IEEE, ANSI, UL 857, CSA, and NEMA—support regulatory alignment across regions, giving confidence in performance under diverse conditions. Compact dimensions and a practical weight support easy integration with existing footprints in factory floors and utility rooms.

FAQs
The P3BFDB3080 is designed as a three-pole Pow-R-Way III plug-in unit intended for Eaton busway systems. It integrates into modular busway configurations that accept plug-in breakers aligned with the Pow-R-Way III family. For exact enclosure compatibility, verify the catalog number against your busway module and mounting footprint to ensure secure mechanical fit and wiring access.
An 80A amperage rating defines the continuous operating capacity, while 18 kAIC at 240V specifies the interrupt capability at short-circuit conditions. Together, they limit fault energy, reduce arc-flash risk, and protect downstream motors and drives. This combination supports reliable operation in medium-to-large industrial loads common in manufacturing and processing facilities.
Yes, the unit supports 50% integral or housing grounding. This provides a straightforward grounding path that minimizes external wiring and simplifies code compliance during installation. The option reduces field engineering time and improves fault-path reliability, which is especially beneficial in modular busway installations where quick, repeatable grounding is desired.
The P3BFDB3080 carries IEEE Certification, ANSI listings, UL 857, and CSA Certification, with NEMA compliance as well. These certifications validate performance under safety and reliability standards across regions, helping you meet procurement specs and regulatory requirements for industrial power distribution equipment.
Maintenance benefits include faster replacement due to plug-in design, reducing downtime during outages. The 25 lb unit fits typical busway enclosures, easing handling during service. ROI is driven by shorter maintenance windows, lower field labor for replacements, and enhanced protection that minimizes unplanned outages and equipment damage over the life of the installation.
