Three-pole design with an F frame provides consistent, high-performance protection for three-phase busway circuits, reducing arcing risk and improving protection coordination. This translates to safer startup sequences and easier panel integration in high-density manufacturing environments. The plug-in architecture enables rapid field replacement, minimizing downtime during maintenance and reducing overall labor costs while preserving system uptime. With 65 kAIC at 240 VAC, 25 kAIC at 480 VAC, and 18 kAIC at 600 VAC, it delivers strong fault-current interruption for diverse industrial loads, supporting critical machinery and process lines. The 100% Neutral and 50% Internal Ground grounding options enhance fault path clarity and electrical safety, simplifying compliance with strict plant safety programs. Compliance and warranty details — NEMA, UL 857, ANSI, CSA, IEEE certifications with a one-year to eighteen-month warranty window — reinforce total cost of ownership by limiting unexpected service expenses. Compatible with the Pow-R-Way III family, the unit offers scalable protection as your busway network expands and loads shift.

FAQs
The P3BFD3125GN is designed for seamless integration with Eaton Pow-R-Way III busway configurations. It uses a three-pole, F-frame design and plug-in architecture that aligns with standardPow-R-Way III breakers, enabling quick field swaps without disturbing busways. This reduces commissioning time and minimizes panel downtime during maintenance or expansion projects.
This unit is rated for 125A with interrupt ratings of 65 kAIC at 240 VAC, 25 kAIC at 480 VAC, and 18 kAIC at 600 VAC. Neutral handling is specified as 100% Neutral, with 50% internal grounding, providing robust fault paths and safer operation in three-phase busway systems.
Yes. The three-pole, F-frame Pow-R-Way III design is specifically suited for busway protection in manufacturing and other industrial environments. With 125A rating and high interrupt capabilities, it supports reliable protection for essential machinery while fitting neatly into standardized panel layouts and Eaton’s busway architectures.
The P3BFD3125GN carries UL 857 listing and ANSI/CSA/IEEE certifications, along with NEMA compliance. These certifications confirm safety, interoperability with control gear, and suitability for industrial power distribution applications.
Warranty terms are Eaton’s policy: one year from installation or eighteen months from shipment, whichever occurs first. This helps stabilize maintenance costs and provides a clear framework for service planning. The plug-in design also reduces maintenance labor and downtime, contributing to lower total cost of ownership over the equipment lifecycle.
