The 70 A amperage rating paired with the three-pole F-frame design offers targeted protection for moderate busway feeders, enabling efficient load management and reduced wiring complexity in new builds or retrofits. This translates to lower installation time, fewer field adjustments, and improved equipment uptime in busy electrical rooms. The plug-in unit format supports rapid replacements, minimizing downtime during maintenance or expansions while maintaining consistent electrical characteristics across the Pow-R-Way III family. By leveraging a defined grounding strategy—50% integral or housing ground—the solution ensures a safe fault path and simplifies conduit routing, contributing to lower commissioning costs and improved personnel safety. The 12.36 in length, 21.2 in height, and 5.43 in width deliver a compact footprint suitable for medium-density busway configurations, with an estimated 25 lb handling weight improving on-site maneuverability. This combination supports scalable protection strategies, facilitating future capacity additions without large-scale panel rework. Certification-aligned design choices further reduce risk in regulated environments, improving procurement confidence and project timelines. For installers and engineers, the unit’s compatibility with existing Pow-R-Way III components offers a familiar, reliable integration pathway that minimizes rework and ensures consistent performance across installations in manufacturing, data centers, and process facilities.

FAQs
For installation, verify three-pole, F-frame compatibility and ensure the unit is mounted within the busway enclosure mounting dimensions. Use the 50% integral/housing grounding option as specified, and confirm neutral is configured at 100%. Ensure tight torque on connections and maintain clearances for heat dissipation. The plug-in design supports rapid replacement, reducing downtime during maintenance.
The P3BFD3070N is rated at 70 A with interrupt ratings of 65 kAIC at 240 Vac, 25 kAIC at 480 Vac, and 18 kAIC at 600 Vac. This performance supports feeder protection across typical busway voltages, enabling reliable fault interruption and minimizing downstream damage in high-energy short circuits while maintaining system uptime.
Yes. It is a three-pole, F-frame plug-in unit designed for busway protection, with a compact footprint (12.36 in L, 21.2 in H, 5.43 in W) and 25 lb weight. Its plug-in format reduces installation footprint and simplifies replacement in crowded electrical environments, supporting scalable, modular protection as facilities evolve.
The unit carries NEMA compliance, UL 857, CSA Certification, and IEEE Certification. These certifications ensure safety, reliable performance, and regulatory alignment across North American markets, simplifying procurement, installation approvals, and ongoing compliance for industrial facilities and regulated environments.
Maintenance benefits include faster replacements due to the plug-in design, reduced labor costs, and predictable maintenance intervals backed by a one-year warranty (or 18 months from shipment). ROI stems from improved uptime, lower spare-part complexity, standardized protection across systems, and the ability to support future capacity expansions with minimal rework.
