Pow-R-Way III design and three-pole plug-in unit optimize busway distribution by simplifying installation and reducing field adjustments, enabling faster commissioning and less downtime in busy facilities. The business impact is measurable: accelerated wiring, fewer mis-matches with busway fixtures, and reliable protection for feeder lines. It is ideal for busway systems requiring compact, modular protection at 40A, helping electrical teams meet tight project schedules while maintaining safety margins in demanding environments. The high interrupt ratings—100 kAIC at 220-240V, 70 kAIC at 380-415V, and 14 kAIC at 660-690V—provide robust fault protection, reducing collateral damage and maintenance costs in high-energy applications. This unit’s 100% neutral and 50% internal grounding simplify grounding schemes and improve fault clarity for maintenance crews. The vertical hanger design supports ergonomic installation in vertical bus runs, improving accessibility and reducing installation time. Certifications (ANSI/IEEE, UL 857, CSA) and NEMA compliance reinforce regulatory adherence, lowering risk during inspections. Finally, the 40A amperage rating with a three-pole F-frame design aligns with common industrial feeder requirements, enabling scalable protection within Pow-R-Way III architectures and ensuring long-term compatibility with a broad range of Eaton accessories.
