The unit employs a three-pole, F-frame breaker optimized for plug-in busway modules. This topology delivers balanced protection and a compact footprint, helping you fit protection right where power enters a bank of busways. It’s designed for seamless integration with Eaton's Pow-R-Way III family, reducing installation steps and replacement time on the line. High interrupt ratings provide robust fault-current handling—100 kAIC at 220-240V, 70 kAIC at 380-415V, and 14 kAIC at 660-690V—minimizing the need for oversizing and enhancing system safety in motor and high-load busway applications. Neutral distribution is 100% with 50% internal grounding, improving fault management and personnel safety. The device meets NEMA compliance and ANSI UL 857, CSA, and IEEE certifications, supporting compliance-driven projects and procurement. Its footprint and plug-in design simplify retrofit and expansion, reducing downtime and lifecycle costs in evolving facilities. Designed for compatibility with the Pow-R-Way III family, it offers straightforward maintenance, rapid part replacement, and predictable performance in harsh industrial environments.

FAQs
Yes. The P3BHFWF3040GN is a three-pole, F-frame plug-in circuit breaker designed specifically for Pow-R-Way III busway configurations. It integrates with the Pow-R-Way III family to enable rapid installation, straightforward replacements, and scalable protection across busway sections. Verify catalog alignment (P3BHFWF3040GN) and busway section compatibility before pairing with existing equipment.
The 100 kAIC rating at 220-240V indicates the maximum fault current this breaker can interrupt safely at that voltage range. This rating helps protect downstream equipment in medium- to high-current busway circuits, reducing the risk of damage during short-circuit events and allowing for a more compact protective solution without oversizing.
This unit is NEMA compliant and carries ANSI UL 857, CSA Certified, and IEEE Certified markings. These certifications ensure compliance with North American electrical codes and industry best practices, facilitating procurement, qualification testing, and regulatory acceptance in commercial and industrial installations.
The device measures 12.36 in in depth, 21.2 in in height, and 5.43 in in width, with a shipping weight around 25 lb. These dimensions support planning in crowded electrical rooms or panel banks and help ensure compatible packaging within busway assemblies and adjacent components.
Using this plug-in unit reduces installation time through a plug-in design, lowers wiring complexity, and enables modular protection upgrades as the plant expands. The 40A rating with 100% neutral and 50% internal grounding supports safer, scalable power distribution, while high interrupt ratings improve protection reliability and reduce total cost of ownership over the system lifecycle.
