70A amperage rating enables targeted protection for typical busway feeder circuits, reducing conductor waste and keeping protection coordination straightforward. This fits three-pole, F-frame configurations found in Pow-R-Way III systems, delivering tangible efficiency for design engineers and procurement teams. The unit’s 18 kAIC interrupt rating at 240 Vac and 14 kAIC at 480/600 Vac provides robust fault tolerance for motor loads and high inrush scenarios, minimizing unplanned outages and equipment damage. With 100% Neutral, current balance is maintained across all poles, simplifying multi-wire branch circuit design and improving coordination with upstream protection. Grounding options offer 50% integral or housing ground, reducing external wiring and speeding installation in dense busway layouts. Compliance is built-in with UL 857, CSA, IEEE, and ANSI certifications, guaranteeing interoperability and regulatory alignment across distributed systems. The compact footprint (12.36 in L × 5.43 in W × 21.2 in H) and a 25 lb weight enable straightforward retrofits and modular expansions within existing enclosures. A one-year Eaton warranty supports procurement planning and ongoing maintenance, while the plug-in design minimizes downtime during replacement or upgrades. This combination of protection, ease of installation, and standards compliance makes it a practical choice for modern industrial power management and distribution.
