Sprinkler-proof plug-in
Three-pole Pow-R-Way III design provides balanced protection for three-phase busway runs, simplifying field installation and reducing wiring errors. The unit supports frame ratings from 15 to 225 A, with a dedicated 100 A rating available for common feeder applications. In industrial power networks that rely on busway distribution, this configuration improves fault management and subsystem isolation, delivering predictable protection across critical loads. Sprinkler-proof plug-in construction enhances reliability in environments with exposure to water or sprinklers, minimizing nuisance trips and maintenance. The design also supports a 100% neutral configuration and 50% integral ground, helping ensure proper neutral return paths and faster grounding during fault events. For installers, the plug-in interface reduces commissioning time and simplifies retrofits. With 65 kAIC at 240 VAC, 25 kAIC at 480 VAC, and 18 kAIC at 600 VAC, the P3BFD3100NSP accommodates substantial fault currents without compromising system integrity, translating to safer switchgear operation and extended equipment life under short-circuit stress. Certification coverage—including IEEE, UL 857, ANSI, CSA and NEMA compliance—supports regulatory acceptance across industries. Physical footprint measures 12.36 in L, 21.2 in H, and 5.43 in W, with a weight of 25 lb, enabling installation in standard enclosures without dedicated space. The unit’s compatibility with Pow-R-Way III busway and sprinkler-proof plug-in design streamlines OEM and retrofit projects. Clear labeling and standardized cataloging simplify maintenance planning and parts replacement. Warranty terms follow Eaton policy 25-000, offering one year from installation or eighteen months from shipment, whichever occurs first. Long-term value is enhanced by widely available datasheets and the Eaton support ecosystem, reducing mean time to repair and ensuring ongoing compliance. In short, the P3BFD3100NSP combines robust protection with lifecycle cost savings for demanding facilities.
