Eaton P3BFD3040NSP Plug-in Circuit Breaker - 65 kAIC

Three-pole, F-frame design provides consistent three-phase protection for busway runs, reducing coordination errors and arc-flash risk. The business impact is safer commissioning and smoother maintenance, especially in dense plant layouts where space constraints are common. This is ideal for Pow-R-Way III installations where reliable phase balance is crucial. Sprinkler-proof plug-in construction minimizes moisture ingress and foreign-object intrusion, delivering higher uptime in facilities with fire suppression requirements. The resulting benefit is lower unplanned downtime and fewer field re-works during maintenance windows, particularly in harsh environments or high-humidity areas. The unit offers 65 kAIC at 240 Vac, 25 kAIC at 480 Vac, and 18 kAIC at 600 Vac, enabling fault-current withstand for robust industrial profiles. This translates to improved protection for heavy machinery, conveyors, and automation panels with high short-circuit demands. Its 100% Neutral option and 50% Integral/Housing grounding simplify grounding schemes, reducing wiring complexity and installation time across multi-panel busways. In practice, technicians appreciate quick plug-in mounting, standardized busway integration, and consistent performance across varying fault levels. With a compact footprint—12.36 in long, 21.2 in high, 5.43 in wide—and a modest 25 lb weight—the P3BFD3040NSP fits standard enclosures and supports safer, faster retrofits in evolving facilities. The design aligns with NEMA compliance and provides a dependable, scalable solution for growing power distribution needs.
