Plug
The Pow-R-Way III plug-in unit delivers a modular protection platform that simplifies installation for busway systems. The three-pole FD frame and 100 A rating translate into precise protection for three‑phase loads with predictable trip characteristics, reducing unplanned downtime and extending motor life. Its high interrupt ratings—65 kAIC at 240 Vac, 25 kAIC at 480 Vac, and 18 kAIC at 600 Vac—provide robust short-circuit protection for diverse industrial feeders, enabling safer starts and less equipment damage. Grounding flexibility with 50% integral or housing grounding helps match system practice without costly retrofits. Compliance with UL 857, ANSI, CSA, and NEMA standards ensures procurement teams meet regulatory requirements while maintaining supply chain stability. The compact busway-friendly footprint and balanced dimensions support efficient enclosure planning and easier retrofits in existing installations.
