The three-pole Pow-R-Way III plug-in unit uses an F-frame design compatible with busway systems, enabling a secure mechanical fit and rapid replacement. This reduces commissioning time for modular distribution setups and minimizes wiring complexity in field installations, delivering measurable efficiency gains. In practice, technicians experience smoother upgrades within Eaton Pow-R-Way III layouts, translating to shorter downtime and simplified spare-part planning. The unit carries a 50A amperage rating with a 100 kAIC interrupt capacity at 240/480 Vac and 25 kAIC at 600 Vac, ensuring robust short-circuit protection for high-demand applications like manufacturing lines and data centers. This high interrupt rating lowers fault energy, protecting downstream equipment and supporting safer, more reliable operations. Neutral options at 100% and grounding options at 50% integral or housing provide flexible configurations for balanced loads and code-compliant grounding, streamlining installation across varied facilities. With NEMA compliance and UL/CSA/IEEE certifications, customers gain regulatory confidence and easier procurement for industrial buses and plug-in protection. The compact plug-in design also simplifies maintenance; technicians can swap modules quickly, reducing downtime and extending asset life in continuous-operation environments. Overall, the device supports lifecycle cost reductions, better uptime metrics, and compatibility with modern busway systems, reinforcing a resilient electrical distribution strategy.

FAQs
Its three-pole Pow-R-Way III plug-in design is optimized for busway systems and Eaton Pow-R-Way III architectures. It features a three-pole F-frame breaker, 50% integral or housing grounding, and 100% neutral, delivering straightforward integration with modular busway assemblies and standard panels. The unit aligns with NEMA requirements and supports quick plug-in replacement in field installations.
The 100 kAIC interrupt rating at 240/480 Vac provides robust short-circuit protection, reducing fault energy and limiting damage to equipment. For harsh environments like manufacturing floors or data centers, this high rating translates to higher uptime, lower transients, and simplified coordination with upstream protective devices.
Yes for data centers due to high reliability and UL/CSA/IEEE certifications; however, it is not inherently rated for hazardous environments. Its NEMA compliance and grounding options support clean power distribution, and the device can be configured with neutral and grounding to meet data center power density and redundancy requirements.
Maintenance focuses on periodic terminal inspection, verifying torque, and checking grounding integrity. The plug-in design allows quick replacement without rewiring, minimizing downtime. Follow Eaton’s recommended maintenance schedule and use genuine spare parts to maintain reliability across shifts and long service lives.
The P3BHFD3050N carries UL 857 certification along with ANSI, IEEE, and CSA marks and is NEMA compliant. These certifications streamline procurement, support regulatory approvals in North America, and align with standard industrial busway and plug-in protection practices.
