The P3BHFD3045GN is a 3-pole, 45A plug-in unit with a Pow-R-Way III busway interface that leverages a 50% internal grounding scheme and 100% neutral configuration. This combination reduces field wiring complexity while ensuring reliable fault return paths, delivering faster installation and easier serviceability for busy electrical rooms. The 12.36 in depth, 21.2 in height, and 5.43 in width footprint fits compact panels while still delivering robust protection, with a 25 lb weight that supports manageable handling during retrofit projects. With a 100 kAIC interrupt rating at 240 Vac and 480 Vac, and 25 kAIC at 600 Vac, it protects feeders against high fault currents common in industrial facilities, improving uptime and equipment longevity. Certification to IEEE, CSA, ANSI, and UL 857 simplifies compliance and procurement across multi-site deployments. The 100% neutral option ensures accurate monitoring of sensitive loads, and the 50% internal ground minimizes external wiring while maintaining safety. Compatibility with F-frame breakers supports Eaton’s broader spare-part strategy, reducing total-cost-of-ownership and slowing obsolescence. Documentation and warranty alignment further streamline project planning and field support.

FAQs
For reliable mounting, ensure the plug-in unit is seated squarely within the Pow-R-Way III busway interface. Verify the F-frame compatibility, confirm the 3-pole arrangement aligns with your feeder configuration, and follow Eaton’s mounting clearances to prevent binding during plug-in removal or replacement. Use the unit’s 12.36 in depth, 21.2 in height, and 5.43 in width footprint to plan space in the electrical room and coordinate with adjacent devices for proper cooling and accessibility.
The unit provides a 45A amperage rating with a 100 kAIC interrupt rating at 240 Vac and 480 Vac, plus 25 kAIC at 600 Vac. These ratings support protection for feeders in facilities with high fault currents, enabling rapid disconnection and limiting damage to busways and downstream equipment. The 100% neutral option also ensures accurate sensing for balanced and unbalanced loads, improving protection accuracy.
Yes, the P3BHFD3045GN is designed for seamless integration with Eaton Pow-R-Way III busway systems. It offers 50% internal grounding, which reduces external wiring, and a 100% neutral configuration for stable return paths and accurate protection of sensitive loads. This combination supports straightforward upgrades and retrofits without major rewiring or cabinet modifications.
The unit is IEEE Certified, CSA Certified, ANSI compliant, and UL 857 listed, with NEMA compliance noted. These certifications cover safety, compatibility with electrical standards, and regulatory acceptance across common markets, helping you meet procurement specifications, insurance requirements, and industry guidelines during audits and commissioning.
The plug-in design enables rapid field replacement, reducing downtime during fault events or maintenance. Its compatibility with existing Eaton components minimizes spare-part complexity, while the robust 100 kAIC protection and 100% neutral configuration improve reliability for critical feeders. Over time, this translates to lower maintenance costs, shorter outage durations, and improved overall equipment effectiveness (OEE) in industrial environments.
