Three-pole E-frame design with a 40A rating delivers targeted protection for busway feeders, enabling precise trip curves that align with downstream protection. This configuration reduces nuisance trips and simplifies coordination with upstream devices, cutting arc-flash risk and downtime during faults. The plug-in unit format accelerates field installation in crowded switchgear, allowing faster upgrades without rewiring and minimizing commissioning risk for new builds or retrofit projects. High interrupt ratings of 18 kAIC at 240 VAC and 14 kAIC at 480 VAC provide robust fault-current handling across typical industrial networks. By preserving circuit integrity during high-energy faults, the unit minimizes equipment damage and improves safety margins for motor loads, drives, and critical processing lines. This protection capability translates into lower total cost of ownership through reduced maintenance windows and longer equipment life. Designed for Pow-R-Way III busway systems, the plug-in unit integrates seamlessly with Eaton products and supports straightforward step-in installation in modular assemblies. The grounding option offering 50% integral or housing grounding simplifies field wiring and reduces the risk of ground faults in complex busway configurations. Compact dimensions—12.36 in depth, 21.2 in height, and 5.43 in width—coupled with a 25 lb weight, enable easy handling, quick swaps, and minimal space impact in tight panels. The 40A, three-pole setup complements standard protection schemes while preserving panel layout flexibility for future expansion. Compliance and certifications underwrite procurement confidence. UL 857, IEEE, ANSI, CSA certifications, and NEMA compliance provide cross-border acceptability and align with stringent safety programs. The documented warranty (one year from installation or 18 months from shipment) helps facilities plan maintenance and budget with certainty. Operational benefits extend to maintenance teams who appreciate clear specifications, consistent performance data, and readily available datasheets, including the Eaton specification sheet for P3BEHD3040. In practice, this translates to faster audits, easier training, and smoother lifecycle management for industrial power distribution systems.
