Three-pole F-frame protection in a Pow-R-Way III plug-in unit delivers coordinated interrupt performance for busway circuits. The 90A rating paired with 18 kAIC at 240 Vac ensures rapid fault clearance, reducing arc energy exposure and downtime on critical production lines. This is ideal for medium-duty loads within the 15-225 A family. 50% integral grounding reduces wiring complexity and improves safety, enabling safer, quicker connections in dense panels and on constrained layouts. The compact footprint (12.36 in L x 21.2 in H x 5.43 in W) and 25 lb weight simplify installation, relocation, and spare-part provisioning, supporting modular expansion without sacrificing space. Compliance with UL 857, ANSI/IEEE, CSA, and NEMA standards provides regulatory alignment and audit-ready documentation for industrial deployments. Warranty terms and robust protection coordination further bolster total cost of ownership and maintenance planning.

FAQs
The P3BFDB3090 is a three-pole Pow-R-Way III plug-in circuit breaker designed for Eaton busway protection systems. It integrates with standard Pow-R-Way busways and uses a compact form factor (12.36 in L x 21.2 in H x 5.43 in W) weighing 25 lb, simplifying mounting and replacement. The unit also features 50% integral grounding for safer connections.
The unit is a 90A, three-pole breaker with 18 kAIC interrupt at 240 Vac and 14 kAIC at 480 Vac and 600 Vac. This combination provides fast fault clearing for typical industrial loads while maintaining coordination with downstream protection. Its three-pole configuration suits multi-phase busway applications and supports reliable system protection.
Yes. The P3BFDB3090 is explicitly designed for three-pole protection in busway-driven industrial lines. Its Pow-R-Way III design, UL 857 and ANSI/IEEE CSA certifications, and 90A rating ensure dependable protection for medium-duty loads. The grounding option and compact footprint simplify installation in tight spaces typical of modern manufacturing environments.
The P3BFDB3090 carries UL 857 certification, ANSI/IEEE certification, CSA certification, and is NEMA compliant. These standards confirm electrical performance, safety, and interoperability within North American facilities and allied markets. They also support regulatory audits, compatibility with other certified components, and streamlined procurement processes.
The unit includes a warranty of one year from installation or eighteen months from shipment, whichever comes first, supporting quick replacement in the field. Its plug-in design reduces spindle downtime and spare-parts inventory, while the robust interrupt ratings help minimize unplanned outages. Combined with its modular busway compatibility, this delivers favorable total cost of ownership and predictable maintenance timelines.
