Eaton P3BHFD3090N Pow-R-Way III circuit breaker - UL 857
Part Number: P3BHFD3090N
Quick Summary
Eaton Pow-R-Way III circuit breaker plug-in unit provides reliable overcurrent protection for busway systems. Installers frequently face space constraints and compatibility gaps when upgrading modular power layouts, making it hard to achieve quick, code-compliant installations. This unit ships UL 857, ANSI and IEEE certifications with NEMA compliance, and offers 100% neutral alongside 50% integral ground to support safe, predictable operation. By combining a compact plug-in form with a three-pole F-frame design and high interrupt ratings, it accelerates commissioning, simplifies maintenance, and reduces downstream rework for industrial facilities and service crews alike.

Three-pole, F-frame plug-in design delivers robust protection in a compact footprint, reducing panel depth and enabling easier busway installation. Business impact: saves space, cut wiring complexity, and shorten panel builds; application: busway feeders in manufacturing and distribution facilities. High interrupt ratings—100 kAIC at 240 and 480 Vac, 25 kAIC at 600 Vac—allow reliable fault clearing for high-energy systems, minimizing downtime and equipment damage. Application: critical feeders to motors and presses; impact: lower energy at fault and faster restoration. 100% neutral with 50% integral/housing grounding simplifies grounding schemes, improving safety and reducing field wiring costs. Application: systems requiring robust grounding and regulatory alignment; impact: safer, compliant installations. Certifications including UL 857, ANSI, IEEE, and CSA provide regulatory confidence, facilitating procurement and cross-site compliance. Application: regulated facilities; impact: smoother audits and fewer design changes. NEMA compliance and modular busway compatibility streamline integration with Eaton and third-party busway components. Application: modular power portfolios; impact: faster deployment and future-proofing. Warranty coverage of one year from installation or eighteen months from shipment adds predictable post-sale support, reducing total cost of ownership. Application: asset-intensive environments; impact: improved ROI through reduced downtime and faster service.

FAQs
For successful installation, verify compatibility with the busway profile and ensure correct three-pole mounting on the F-frame. Follow the wiring diagram for neutral and grounding connections, apply proper torque to terminals, and maintain clearances for heat dissipation. The unit’s 100% neutral and 50% integral grounding simplify grounding design while meeting UL 857 and NEMA requirements.
The device is rated 90A with interrupt ratings of 100 kAIC at 240 Vac and 480 Vac, and 25 kAIC at 600 Vac. It is a three-pole plug-in unit with a busway application, offering 100% neutral and 50% integral/housing grounding to support safe, compliant operation in modular power systems.
Yes. The P3BHFD3090N carries UL 857 certification along with ANSI and IEEE, CSA certifications and NEMA compliance, ensuring safe integration with NEMA-listed busway products and standardized electrical installations across facilities.
The unit provides 50% integral or housing grounding, offering a flexible grounding path that simplifies installation and reduces external grounding conductor runs. This supports safer fault-clearing paths, meets NEC expectations, and aligns with busway system grounding practices used in industrial installs.
This plug-in breaker minimizes downtime through rapid installation and reliable fault protection, lowering maintenance frequency. With a one-year warranty (or 18 months from shipment), and proven UL/ANSI/IEEE/CSA certification, the total cost of ownership drops as fewer field reworks are required, while outages are reduced and commissioning is accelerated.
