3-Pole, 150A rating with an F frame provides dependable fault isolation for busway feeders, reducing exposure to overloads. In practice, this enables quick plug-in replacement without rewiring, accelerating maintenance windows in crowded electrical rooms. High interrupt ratings of 18 kAIC at 240 V, and 14 kAIC at 480–600 V, enable the device to absorb surge energy typical in modern plants while protecting feeders and downstream motors. This translates to lower energy-related damage and fewer unplanned outages during commissioning. Certifications and compliance—IEEE and CSA certifications, ANSI listings, UL 857 recognition—along with NEMA compliance, provide regulatory assurance, simplify supplier qualification, and ease audits in regulated environments. That certification footprint supports procurement teams seeking proven reliability for critical infrastructure. Grounding options of 50% internal ground and 100% neutral configuration simplify protective-earth design and reduce field wiring complexity, helping installers meet safety standards without sacrificing performance. Installation footprint and compatibility matter in busy facilities; at 12.36 in depth, 21.2 in height, 5.43 in width, and about 25 lb weight, the plug-in unit fits alongside existing busway assemblies and minimizes downtime during upgrades. Real-world service teams benefit from the standardized frame and the 150A amperage rating, which align with typical plant feeders, enabling predictable protection schemes and easier spares planning. Reliability under harsh industrial conditions is a core consideration. The Pow-R-Way III plug-in unit is designed for dependable operation in busy switchgear environments, where fast access and plug-in replacement minimize downtime. Compatibility and maintenance planning are simplified by Eaton's ecosystem. The P3BFDB3150GN leverages the Pow-R-Way III busway family and is documented in Eaton's specification sheet and partner videos. This supports procurement, enables standardized training, and helps maintenance teams prepare spare parts, reducing lead times for replacements. In today’s regulated environments, this translates into reduced risk, faster recovery after faults, and measurable improvements in overall equipment effectiveness.

FAQs
Install the P3BFDB3150GN as a plug-in unit directly into the Pow-R-Way III busway system. Ensure the 3-Pole, 150A unit sits on the correct frame (F) and align with the busway connectors to avoid misalignment. Use the 50% internal grounding option and connect the 100% neutral as specified. Verify IEEE CSA ANSI UL 857 compliance during commissioning and document the grounding arrangement for safety audits.
The unit is rated for 150A with a 3-Pole configuration and an F frame. It provides interrupt ratings of 18 kAIC at 240 VAC and 14 kAIC at 480 VAC or 600 VAC. These ratings enable protection against high-energy faults typical in industrial facilities, reducing downstream damage and facilitating safe start-ups and testing.
Yes. The P3BFDB3150GN carries IEEE Certified, CSA Certified, ANSI listings, and UL 857 recognition, and it is NEMA compliant. This certification set supports regulatory compliance, audit readiness, and supplier qualification for regulated environments such as manufacturing, data centers, and process facilities.
This plug-in unit is ideal for industrial power distribution within busway systems, where modular protection, rapid replacement, and compact plug-in installation are prioritized. It supports heavy feeders, 150A circuits, and environments requiring robust grounding and neutral configurations, delivering reliable protection in automated facilities and plant-wide electrical distributions.
The plug-in design simplifies field swaps and reduces wiring complexity, cutting downtime during maintenance windows. With standardized Eaton components and documented installation procedures, spare parts planning becomes straightforward, improving mean time to repair (MTTR) and lowering total cost of ownership over the system lifecycle.
