The three-pole F-frame plug-in unit is designed for busway protection, enabling quick integration into existing Eaton busway networks and reducing installation time while maintaining reliable protection. This translates to lower commissioning costs and faster time-to-value for new lines or retrofits. Its 40A rating with 18 kAIC at 240 Vac and 14 kAIC at higher voltages provides robust fault interruption for motor feeders and power distribution panels, improving uptime and minimizing equipment damage. Compliance with NEMA, ANSI CSA, IEEE, and UL 857 reduces procurement risk and streamlines regulatory approvals across facilities. The 50% internal grounding option supports safer, more predictable fault paths in dense electrical rooms. Compact dimensions (12.36 in depth, 21.2 in height, 5.43 in width) and a 25 lb weight simplify handling, service, and spare-part planning. Warranty covers one year from installation or 18 months from shipment, whichever comes first, protecting your investment during the critical early life of the asset. This plug-in unit aligns with common busway assemblies, easing replacement during routine maintenance and facilitating scalable protection as loads grow.

FAQs
Install the P3BFDB3040G into a compatible three-pole busway section designed for Pow-R-Way III plug-ins. Verify the catalog number, confirm a 40A rating, and ensure proper grounding (50% internal grounding). Secure the unit in the correct orientation, connect supply and load conductors per the installation drawing, and perform a functional test to confirm proper tripping and mechanical alignment. The process leverages a plug-in design to minimize wiring and field assembly time while maintaining UL 857 and NEMA compliance.
The unit is a 40A, three-pole breaker with an 18 kAIC interrupt rating at 240 Vac and 14 kAIC at 480/600 Vac. This combination delivers strong fault interruption for motor feeders and distribution panels while accommodating a range of busway voltages. The ratings support reliable protection with fast fault clearance, reducing equipment damage and downtime in demanding industrial environments.
This breaker is NEMA Compliant and carries ANSI CSA IEEE and UL 857 certifications. Compliance with these standards ensures safety, interoperability, and regulatory alignment across facilities. These certifications simplify procurement, qualify it for a wide range of industrial applications, and support confident spec-in during design reviews and audits.
The P3BFDB3040G is covered by Eaton's warranty policy: one year from the date of installation or eighteen months from shipment, whichever occurs first. This warranty supports protection against manufacturing defects and provides assurance during initial operation. Routine maintenance and periodic inspection should follow Eaton guidance to maximize run time and reliability.
By enabling rapid installation with a plug-in form factor, the unit reduces commissioning time and field wiring labor. Its high interrupt ratings protect critical loads, lowering downtime costs and equipment damage. Standardized certifications simplify approvals, while the 50% internal grounding option enhances safety. Overall, you gain faster time-to-operation, lower spare-parts inventory, and improved lifecycle cost management.
