Special features
Sprinkler-proof plug-in
Sprinkler-proof plug-in design reduces exposure to moisture and nuisance tripping, boosting uptime in damp and sprinkler-protected areas. This translates to lower maintenance costs and faster rearrangements during plant expansions, especially in modular Pow-R-Way III busway layouts. The three-pole F-frame architecture delivers balanced protection across phases, improving feeder reliability and simplifying integration with existing Eaton equipment. Business implications include safer shutdowns and easier fault localization, supporting compliance with industry safety practices in commercial and industrial facilities. Interrupt ratings of 65 kAIC at 240 Vac, 25 kAIC at 480 Vac, and 18 kAIC at 600 Vac enable rapid clearance of high-energy faults without compromising system integrity, delivering measurable reductions in arc flash exposure and downtime. 100% Neutral and 50% Integral Grounding provide flexible grounding strategies that streamline wiring and enhance fault analysis during installation and maintenance. The compact footprint (12.36 in L, 21.2 in H, 5.43 in W) and 25 lb weight ease field mounting in tight spaces, improving install time and reducing crane or access requirements. Compliant with NEMA, UL 857, CSA, and ANSI/IEEE standards, the unit supports procurement programs and reduces regulatory risk, while the included warranty (one year from installation or 18 months from shipment) protects your investment. This combination of protection, compatibility, and safety features makes P3BFD3175NSP a robust choice for busway-based industrial power distribution and sprinkler-zone installations.
