Eaton P3BFD3050N Pow-R-Way III Circuit Breaker - UL 857
Part Number: P3BFD3050N
Quick Summary
The Eaton Pow-R-Way III circuit breaker plug-in unit protects busway power feeds in industrial facilities. Maintaining uptime and safe disconnection amid complex busway configurations is a common challenge. UL 857, IEEE, CSA and ANSI certifications support safety, reliability and interoperability. Coupled with a 50 A rating and multi-voltage interrupt ratings, it scales from 240 to 600 V. In practice, it supports 100% neutral and 50% integral grounding for safer, compliant distribution. End users gain predictable protection timelines and faster retrofit cycles thanks to plug-in modularity. Operational costs drop as maintenance crews leverage common Eaton components across sites. This combination of standards, performance and install simplicity translates to faster commissioning and reduced downtime.

FAQs
Install the P3BFD3050N by mounting the three-pole, F-frame plug-in unit into compatible busway sections. Ensure the device aligns with available neutral and grounding provisions (100% neutral; 50% integral grounding). Follow Eaton wiring diagrams and lockout/tagout procedures. The modular plug-in design shortens commissioning time and reduces on-site wiring complexity, making retrofits and expansions faster and safer.
The P3BFD3050N is rated for 50 A with interrupt ratings of 65 kAIC at 240 VAC, 25 kAIC at 480 VAC, and 18 kAIC at 600 VAC. It features 100% neutral and 50% integral grounding. These ratings support safe operation across a range of industrial busway distributions and fault conditions, improving system reliability.
Yes. Designed for three-pole busway protection, the unit delivers 65 kAIC at 240 VAC and 50 A nominal rating, with full neutral and partial integral grounding. This makes it well-suited for factory floors and manufacturing lines where robust protection and modularity are required for scalable power distribution.
The P3BFD3050N carries UL 857 certification, and is IEEE, CSA, and ANSI certified. These certifications ensure electrical safety, interoperability, and compliance with industry standards across North American markets, reducing regulatory risk and simplifying procurement for regulated facilities.
Warranty terms follow Eaton Policy 25-000: one year from installation or eighteen months from shipment, whichever occurs first. This coverage, combined with Eaton’s service ecosystem, supports predictable maintenance planning, lowers total cost of ownership, and helps protect long-term ROI in busway protection projects.
