Eaton P3BFDC3040G Circuit Breaker Plug-in Unit - UL 857
Part Number: P3BFDC3040G
Quick Summary
Eaton Pow-R-Way III circuit breaker plug-in unit provides reliable overcurrent protection for Pow-R-Way busways in commercial and industrial switchgear. Sizing, installation, and compatibility with existing busway footprints can stall projects and extend downtime. It carries IEEE Certified, CSA Certified, and UL 857 listings, with ANSI alignment to support regulatory compliance in critical facilities. The 40A amperage rating on a 3-pole, F-frame plug-in unit offers scalable protection for feeders and subpanels, while 50% internal grounding simplifies grounding schemes. For engineering teams, this translates into faster commissioning, reduced spare parts inventories, and safer, more maintainable electrical distribution.

FAQs
The P3BFDC3040G is a 3-pole plug-in unit designed for seamless insertion into Pow-R-Way III busways. Begin by verifying compatibility with the busway frame (F-frame), confirm grounding provisions (50% internal), and ensure the circuit rating matches the feeder’s load. Use standard mounting hardware and follow Eaton’s datasheet guidelines to avoid voiding certifications. This approach minimizes commissioning time and reduces field engineering changes.
The device provides 200 kAIC at 240 VAC, 100 kAIC at 480 VAC, and 35 kAIC at 600 VAC. This enables robust fault current protection across typical industrial and data center applications. Engineers should select the rating based on the worst-case fault current at the facility to ensure full protection without nuisance tripping.
Yes, the P3BFDC3040G is UL 857 listed. It also carries IEEE and CSA certifications and is ANSI-compliant, aligning with common regulatory requirements for industrial power distribution. This certification mix supports compliance during audits and simplifies procurement for facilities seeking formal conformance.
The plug-in unit measures 12.36 inches in depth, 21.2 inches in height, and 5.43 inches in width, with an approximate weight of 25 pounds. These compact dimensions facilitate retrofit projects in space-constrained switchgear rooms and support straightforward installation without cable or busbar rework.
It supports 50% internal grounding, simplifying the grounding scheme within the busway assembly. This option can reduce wiring complexity and installation time, particularly in facilities with standardized internal grounding practices. If broader grounding is required, plan for external grounding connections in accordance with relevant codes and the device’s installation guide.
