Selling Policy 25-000 - Distribution and Control Products and Services
Pow-R-Way III busway integration with a three-pole, K-frame design improves standardization and reduces commissioning time for busway-distribution in manufacturing and warehouses. The unit delivers a 125A rating with interrupt ratings of 200 kAIC at 240 VAC, 100 kAIC at 480 VAC, and 50 kAIC at 600 VAC, translating to lower fault energy and minimized downtime in heavy-load environments. With 100% neutral and 50% integral or housing grounding, system balance and fault clearance are enhanced, supporting safer operations and easier maintenance in modern facilities. The plug-in format enables rapid replacements and simpler field service without extensive rewiring, while UL 857, ANSI, CSA, IEEE, and NEMA compliance provide confidence for regulatory-aligned installations in industrial plants, data centers, and distribution hubs. This combination improves lifecycle costs by reducing spare-part complexity and facilitating scalable upgrades as load profiles evolve.
