Eaton P3BFWF3080VN Pow-R-Way III Circuit Breaker - 40 kAIC
Part Number: P3BFWF3080VN
Quick Summary
Pow-R-Way III circuit breaker plug-in unit is a robust protection solution for busway-fed electrical distributions in industrial facilities. This three-pole plug-in unit delivers reliable short-circuit interruption with an 80A rating and a 40 kAIC interrupt capability at 240V. Engineers often struggle with space constraints and mounting compatibility in vertical busway configurations; this unit’s vertical hanger and plug-in design help minimize footprint while preserving serviceability. Certified for NEMA compliance and supported by CSA, UL 857, and IEEE certifications, it meets stringent safety and performance standards. In addition to dependable protection, the 100% neutral option and 50% integral grounding simplify wiring and grounding schemes, reducing install time and labor costs. The result is a safer, more reliable busway distribution solution with ready availability for maintenance and upgrades, and improved uptime for critical loads.

Three-pole plug-in design with Pow-R-Way III architecture reduces installation time and panel footprint, facilitating rapid deployment in new builds and retrofit projects. This enables shorter project timelines and cost savings on space and labor, especially in compact industrial cabinets and retrofit scenarios. The 80A rating combined with a 40 kAIC interrupt rating at 240V provides robust fault current handling, lowering the risk of equipment damage and unplanned downtime in high-demand facilities. In practice, this translates to safer, more reliable startup sequences and reduced risk during short-circuit events. The unit’s 100% neutral and 50% integral grounding simplify wiring schemes, cutting field-wiring complexity and potential grounding errors. Vertical hanger design and busway compatibility minimize clearance requirements, making maintenance and part replacement faster and less disruptive. Compliance with NEMA, CSA, UL 857, and IEEE standards gives engineers confidence in safety, performance, and long-term reliability, while a compact footprint supports scalable power distribution for growing facilities.

FAQs
Installation begins with confirming busway compatibility and the three-pole configuration. The unit uses a vertical hanger for mounting and a plug-in connection to the busway system. Ensure 240V supply, connect the neutral (100%), and complete the grounding path (50% integral housing grounding). Refer to the Eaton specification sheet for torque values and step-by-step sequencing to minimize downtime and ensure code-compliant wiring.
The device is rated for 80A with an interrupt rating of 40 kAIC at 220-240 Vac. It operates at 240V with 100% neutral and 50% integral grounding. It is a three-pole, F-frame breaker designed for busway distribution, with H class fuse type noted in the physical specifications for compatibility considerations.
Yes. It is designed specifically for busway distributions, featuring a vertical hanger and plug-in mechanism to simplify installation. With a robust 40 kAIC interrupt rating at 240V and NEMA/UL/CSA/IEEE certifications, it provides reliable protection for industrial loads while reducing wiring complexity and installation time.
The P3BFWF3080VN is CSA Certified, UL 857 listed, IEEE Certified, and NEMA Compliant. These certifications validate safety, performance, and compatibility with standard industrial power systems, supporting compliance with common electrical installation codes and facilitating procurement approvals in regulated environments.
Warranty follows Eaton’s policy: one year from installation or eighteen months from shipment, whichever occurs first. Routine maintenance is typically limited to periodic inspection of connections and grounding, with ongoing reliability supported by the unit’s robust fault current rating and NEMA/UL/CSA/IEEE certifications, contributing to reduced downtime and predictable lifecycle costs.
