Eaton P3BKDC3175 Pow-R-Way III plug-in circuit - UL 857
Part Number: P3BKDC3175
Quick Summary
Eaton Pow-R-Way III circuit breaker plug-in unit protects busway distributions in industrial facilities. Engineers often struggle to provide fast fault clearance on long busways without sacrificing uptime. This unit carries UL 857, ANSI/IEEE, and CSA certifications, confirming compliance and reliable operation in demanding environments. With three-pole, K-frame construction and a 175A rating, it delivers robust protection for mid-range power feeds while accommodating high interrupt levels (200 kAIC at 240 Vac, 100 kAIC at 480 Vac, 50 kAIC at 600 Vac). The design supports straightforward field installation and robust grounding options, delivering lower total cost of ownership and improved system reliability for electrical distribution upgrades.

Plug-in design enables quick, bolt-free installation in Pow-R-Way III busway runs, dramatically cutting commissioning time and field labor costs. This translates to faster project turns and reduced downtime during upgrades or repairs. Three-pole, K-frame construction delivers consistent interrupt performance and reliable compatibility with standard busway sections, supporting safer, more predictable protection for critical loads. A high interrupt rating of up to 200 kAIC at 240 Vac (plus 100 kAIC at 480 Vac and 50 kAIC at 600 Vac) reduces arcing damage and enables safer fault clearance in demanding facilities. Grounding options of 50% integral or housing grounding simplify integration with existing grounding schemes and minimize extra hardware. Compliance with UL 857, ANSI, IEEE, CSA, and NEMA standards provides confidence for regulated industries while easing procurement and audit requirements. With dimensions of 13.29 in (L) × 34.41 in (H) × 7.79 in (W) and a weight of 53 lb, the unit fits common enclosure footprints and supports safer, more efficient shipping and handling. Compatibility with the Pow-R-Way III busway ecosystem streamlines installation, reduces lifecycle risk, and supports scalable protection as electrical distribution grows.

FAQs
The P3BKDC3175 is a three-pole plug-in unit engineered for seamless integration with Eaton Pow-R-Way III busway installations. Its K-frame design and plug-in configuration simplify field deployment, enabling rapid commissioning while maintaining alignment with standard busway sections. This combination minimizes installation risk, reduces project lead times, and supports scalable protection as your busway network expands.
The unit is rated at 175A with interrupt ratings of up to 200 kAIC at 240 Vac, 100 kAIC at 480 Vac, and 50 kAIC at 600 Vac. These ratings define the maximum fault current it can safely interrupt, guiding proper coordination with upstream protections and ensuring reliable fault clearance in mid-range distribution applications.
Yes. The device carries UL 857, ANSI, IEEE, and CSA certifications and is NEMA compliant. This combination of certifications supports code compliance, safer operation in harsh industrial environments, and easier auditability for regulated industries, making it well suited for manufacturing, processing, and facility electrical upgrades.
The unit provides 50% integral or housing grounding. This flexibility simplifies integration with existing grounding schemes, reduces the need for additional chassis hardware, and helps optimize fault path design. Proper grounding is essential for safety, arc fault mitigation, and reliable protection coordination in busway systems.
Eaton’s policy 25-000 indicates a one-year warranty from installation or eighteen months from shipment, whichever occurs first. This coverage complements standard service offerings and ensures support for installation-related issues, enabling a clearer total cost of ownership calculation and informed maintenance planning.
