Feature → Three-pole 125A protection in an F-frame circuit breaker plug-in unit designed to fit Eaton Pow-R-Way III busway segments. Business Impact → Delivers reliable short-circuit protection while preserving a compact footprint, reducing panel space requirements and easing downstream wiring in dense electrical rooms. Application → Ideal for 3-phase power distribution on Pow-R-Way III busways in manufacturing and processing facilities. Feature → Grounding options with 50% internal grounding and 100% neutral, enabling flexible grounding strategies and robust neutral performance. Business Impact → Simplifies grounding architecture, improves neutral integrity across loads, and reduces wiring complexity and potential miswiring during panel upgrades. Application → Suitable for large-scale distributions where shared neutrals and grounded conductors are common, including data centers, hospitals, and batch plants. Feature → Compliance and certifications: NEMA compliant; IEEE Certified, CSA Certified, ANSI, UL 857 listings. Business Impact → Ensures regulatory alignment, smoother audits, faster project approvals, and wider supply-chain acceptance. Application → Preferred choice for facilities requiring UL 857 protection and international standards across sectors. Feature → Physical footprint and weight: 12.36 in depth, 21.2 in height, 5.43 in width; 25 lb. Business Impact → Predictable installation dimensions simplify panel design and retrofit planning, minimizing enclosure modifications and enabling consistent installation tolerances. Application → Beneficial for retrofit projects and new builds in constrained spaces, plant expansions, or data center edge sites. Feature → Interrupt ratings: 18 kAIC at 240 VAC; 14 kAIC at 480/600 VAC for versatile fault current protection. Business Impact → Higher fault-current handling reduces equipment damage risk, improves safety margins, and supports compliance with short-circuit performance specs. Application → Critical in facilities with elevated fault currents, such as heavy manufacturing lines, power distribution hubs, and distributed generation interfaces.

FAQs
Install the 3-pole, 125A plug-in unit into the designated Pow-R-Way III busway section, ensuring proper alignment with the F-frame configuration. Confirm 50% internal grounding and 100% neutral connections per the datasheet, and verify the unit’s dimensions (12.36 in depth, 21.2 in height, 5.43 in width) fit the enclosure. Follow NEMA and UL 857 requirements during mounting and wiring to maintain compliance and reliable operation.
The P3BFDB3125GN provides 18 kAIC at 240 VAC and 14 kAIC at 480 VAC and 600 VAC. This indicates the maximum fault current the breaker can interrupt without damage or unsafe conditions. Choose the device for systems with fault currents within these limits to ensure effective protection and arc flash safety.
Yes. The 125A, 3-pole plug-in unit is designed for industrial power distribution within Pow-R-Way busways and is compatible with data centers and manufacturing facilities that require reliable UL 857 protection, IEEE/CSA compliance, and robust grounding/neutral performance for scalable loads.
The unit is IEEE Certified, CSA Certified, ANSI compliant, and UL 857 listed, with NEMA compliance. These certifications support regulatory acceptance, ease audits, and facilitate cross-border project approvals in facilities requiring rigorous electrical protection standards.
Modular, plug-in replacement simplifies maintenance and reduces downtime during upgrades. The 125A rating and standardization with Pow-R-Way busways streamline procurement and spares handling, contributing to lower lifecycle costs and faster return on investment in both retrofit and new-build projects.
