Special features
Sprinkler-proof plug-in
Three-pole, F-frame configuration delivers coordinated three-phase protection for busway feeders, reducing nuisance trips during startup and protecting downstream equipment; the 50A rating aligns with typical distribution circuits, enabling seamless integration with existing panels and equipment. In fault events, the 65 kAIC at 240Vac, 25 kAIC at 480Vac, and 18 kAIC at 600Vac provide fast interruption and system safety, minimizing downtime in manufacturing lines. The sprinkler-proof plug-in design enhances reliability in damp or sprinkler-prone environments, reducing corrosion risk and facilitating rapid maintenance swaps to keep lines running. Neutral options of 100% and ground options of 50% integral/housing support flexible grounding schemes, simplifying compliance with site wiring practices and improving fault return paths. Its Pow-R-Way III compatibility enables modular expansion, reducing field install time and enabling scalable power distribution across growing facilities. Compliance with UL 857, IEEE, CSA, and ANSI standards helps streamline audits and regulatory approvals, while the NEMA compliance footprint reinforces rugged operation in harsh industrial conditions.

FAQs
Yes. The P3BFD3050NSP is designed as a plug-in unit within the Pow-R-Way III family, enabling seamless integration with existing busway segments. Its modular plug-in design reduces field wiring and simplifies extensions or replacements without major rework, improving installation speed and reducing commissioning time.
The device provides 65 kAIC at 240 VAC, 25 kAIC at 480 VAC, and 18 kAIC at 600 VAC. These ratings ensure fast clearing of faults for typical industrial feeder configurations and help protect downstream equipment from high fault currents.
The unit supports 100 percent Neutral and 50 percent Integral/Housing Ground. This flexible grounding arrangement accommodates diverse installation practices, improves fault return paths, and supports code-compliant grounding strategies across a range of facilities.
The P3BFD3050NSP carries UL 857, ANSI, CSA certifications, and IEEE components, with NEMA compliance. These certifications facilitate regulatory approvals, supplier qualification, and performance verification during audits, reducing procurement risk and ensuring suitability for harsh industrial environments.
The sprinkler-proof design minimizes moisture ingress and corrosion risk, improving long-term reliability in damp or sprinklered areas. Field swaps are faster, downtime is reduced, and maintenance costs decline due to simpler replacement and module-level protection, contributing to a lower total cost of ownership in manufacturing, data centers, and distribution rooms.
