Plug-in design for the Pow-R-Way III busway system enables rapid installation and straightforward maintenance. This translates to reduced commissioning time, fewer field wiring errors, and lower total cost of ownership in industrial power distribution environments. High interrupt ratings of 65 kAIC at 240 Vac, 25 kAIC at 480 Vac, and 18 kAIC at 600 Vac give engineers confidence in handling high fault currents. In practice, this means improved system protection for motor loads and distribution feeders with diverse voltage levels. Three-pole, F-frame design with 50A rating and 50% integral/housing grounding offers flexible grounding options and compatibility with standard busway rails. Certifications and compliance—UL 857, CSA Certified, IEEE Certified, and NEMA Compliant—streamline regulatory approvals and panel integration. Dimensions and weight (12.36 in L, 21.2 in H, 5.43 in W, 25 lb) support compact panel layouts and retrofit projects. Warranty terms provide risk coverage during installation or shipment window, helping procurement teams plan maintenance budgets. The combination of plug-in ease and robust ratings makes it a dependable choice for busway protection across industrial facilities.

FAQs
The P3BFD3050 is a three-pole plug-in unit designed for Eaton Pow-R-Way III busway configurations. It integrates with standard busway rails, uses an F-frame design, and supports a 50A rating with 50% integral or housing grounding. This combination simplifies retrofits and minimizes field modification, helping project teams accelerate commissioning and maintain consistent grounding practices across panels.
This unit provides a 50A amperage rating with interrupt ratings of 65 kAIC at 240 Vac, 25 kAIC at 480 Vac, and 18 kAIC at 600 Vac. These ratings enable reliable protection across multiple voltage levels typical in industrial power distribution, reducing the likelihood of nuisance tripping while preserving system safety during fault conditions.
Yes. The P3BFD3050 carries UL 857, CSA Certified, and IEEE Certified markings and is NEMA compliant. This certification suite supports regulatory approvals, panel approvals, and interoperability with downstream equipment, easing procurement and integration into regulated facilities such as manufacturing and data centers.
The plug-in design enables rapid replacement and testing without extensive wiring, reducing maintenance time and potential wiring errors. The three-pole F-frame construction supports standardized mounting, and the unit’s compact dimensions fit tight panel footprints. Together, these factors shorten downtime during preventive maintenance and allow quicker fault isolation in high-availability environments.
Warranty terms follow Eaton’s policy: one year from installation or eighteen months from shipment, whichever occurs first. This coverage provides protection against manufacturing defects and supports a predictable maintenance budget, with access to Eaton’s service network for field support and spare parts.
