Selling Policy 25-000 - Distribution and Control Products and Services
Sprinkler-proof plug-in design improves system reliability in sprinkler zones, reducing maintenance calls and leakage risk while simplifying retrofits in existing busway layouts. Business impact: faster commissioning, lower risk of water-related faults, and enhanced safety during startup. Application: busway distribution on commercial and industrial facilities with mixed occupancy. Three-pole F-frame construction supports balanced, three-phase protection for high-demand feeders, delivering 40 kAIC interrupt rating at 220–240 VAC. Business impact: robust fault clearance, minimized equipment damage, and smoother coordination with upstream protection. Application: 100A feeders feeding modular loads via Pow-R-Way III busways. Neutral options of 100% neutral with 50% internal grounding offer wiring flexibility and fault-path reliability, reducing mis-wiring during installation. Application: complex panel assemblies requiring precise grounding strategies. Compact footprint — 12.36 in depth, 5.43 in width, and 21.2 in height with a 25 lb weight — simplifies installation in tight spaces and eases handling during field mounting. Business impact: reduced installation time and improved crew productivity. Compliance and certification assurance come from CSA, ANSI, IEEE, UL 857 with NEMA compliance, supporting procurement and QA processes. Application: projects with stringent regulatory requirements and rigorous supplier qualification. Warranty terms of one year from installation or 18 months from shipment help mitigate risk for maintenance planning and long lead-time projects, contributing to lower total cost of ownership.

FAQs
The P3BFWF3100GNSP is designed specifically for Eaton Pow-R-Way III busway installations. It is a three-pole, F-frame breaker with a sprinkler-proof plug-in design that aligns with standard Pow-R-Way III modules. This enables seamless integration with existing busway feeders and reduces modification work during upgrades or expansions.
The unit is rated for 100 A with a 40 kAIC interrupt rating at 220–240 VAC. This means it can safely interrupt high fault currents up to 40 kiloamps, protecting downstream devices and wiring, while supporting three-pole protection for balanced fault clearing in three-phase systems typical of busway feeders.
The unit’s plug-in accessibility also supports rapid replacement or upgrades without extensive rework, helping maintain protection levels during facility maintenance or renovation projects.
The product is CSA, ANSI, IEEE, and UL 857 certified, with NEMA compliance. These certifications validate electrical safety, performance, and interoperability with North American standards. For procurement, this simplifies regulatory approvals, minimizes qualification risk, and supports compliance-driven project timelines.
Warranty is one year from installation or eighteen months from shipment, whichever occurs first. For maintenance, follow Eaton’s guidelines in the Selling Policy 25-000 and standard commissioning procedures. Regular inspections, torque checks on connections, and prompt replacement of worn plug-in units help sustain protective ratings, reduce downtime, and optimize lifecycle costs.
