Feature → Business Impact → Application: The three-pole Pow-R-Way III plug-in unit provides focused protection for balanced phase protection in busway distributions, enabling faster fault isolation and reduced downtime in manufacturing lines and data centers. This directly supports uptime targets and safer maintenance windows. The 125A rating paired with high interrupt ratings (200 kAIC at 240 Vac, 100 kAIC at 480 Vac, 35 kAIC at 600 Vac) ensures scalable protection for mid-range to high-demand workloads, reducing nuisance trips and improving system reliability in industrial facilities. Grounding flexibility with 50% integral or housing grounding simplifies installation in existing assemblies and helps align with site grounding practices, lowering installation risk and non-conformance. The F-frame design and plug-in approach offer quick swap-out capability, minimizing commissioning time and spare-part burdens during plant upgrades. Compatibility with Pow-R-Way III busways results in a cohesive, modular protection strategy that scales with facility growth. Certification alignment—NEMA, UL 857, IEEE, CSA, ANSI—mitigates procurement risk and expedites approvals for regulated industries.

FAQs
The P3BFDC3125 is a three-pole plug-in circuit breaker designed for Eaton Pow-R-Way III busways. It uses an F-frame, supports 125A loads, and features 50% integral or housing grounding, allowing quick replacements without wiring disassembly. This enables faster commissioning and easier maintenance in busway-based distributions.
The device is rated 125A with interrupt ratings of 200 kAIC at 240 Vac, 100 kAIC at 480 Vac, and 35 kAIC at 600 Vac. These ratings support robust short-circuit protection across typical industrial voltage classes, ensuring reliable coordination with upstream devices in busway systems.
Yes. It is ideal for busway-based power distribution in manufacturing, data centers, and facilities using Eaton Pow-R-Way III busways. The three-pole design ensures balanced protection, while grounding flexibility and a plug-in format simplify installation, commissioning, and future upgrades in electrically demanding environments.
The P3BFDC3125 carries UL 857, IEEE, CSA, and ANSI certifications with NEMA compliance. These approvals support safe, compliant operation in diverse markets, streamline vendor qualification, and accelerate site acceptance tests and utility interconnections on regulated projects.
Maintenance is simplified by the plug-in design and Eaton’s warranty policy (one year from installation or 18 months from shipment). Modular replacement reduces downtime, while high interrupt ratings and busway compatibility minimize spare parts and service costs. Overall, expect lower lifecycle costs and predictable performance in heavy-use facilities.
