FAQs
The P3BFD3175 is designed for three-pole busway installations using Eaton Pow-R-Way III systems. It fits plug-in configurations common in industrial power distribution, data centers, and manufacturing floors. Its 175A rating and multi-kA interrupt capability support scalable protection for growing facilities, while the three-pole design ensures coordinated protection across phases. Compatibility considerations include mounting in standard busway enclosures and ensuring panel space accommodates its 12.36 inch depth, 21.2 inch height, and 5.43 inch width.
Key ratings include 175A amperage with interrupt ratings of 65 kAIC at 240 Vac, 25 kAIC at 480 Vac, and 18 kAIC at 600 Vac. This combination provides fast, reliable fault clearance across common industrial voltages, protecting feeders and connected loads. The unit also supports 50% integral grounding, enhancing safety and fault-path management in busway applications.
Yes. The P3BFD3175 is NEMA compliant and carries certifications including ANSI UL 857, CSA, and IEEE. These standards ensure safety, interoperability with downstream equipment, and suitability for regulated North American facilities. Compliance reduces procurement risk and supports traceable maintenance and service expectations.
Installation is designed for rapid plug-in replacement, minimizing field wiring and downtime during upgrades or maintenance. The modular, plug-in approach lowers labor costs and reduces panel downtime. With documented dimensions and a manageable weight of 25 lb, technicians can plan replacements without heavy lifting, contributing to lower total cost of ownership over the equipment lifecycle.
Eaton provides a warranty under policy 25-000, offering one year from installation or eighteen months from shipment, whichever occurs first.
