Three-pole F-frame design with a 125A rating delivers reliable protection for busway feeders while preserving a compact plug-in footprint. This enables fast device replacement, reduces spare parts inventory, and minimizes downtime during outages or expansions. It's well suited for Pow-R-Way III busway assemblies in manufacturing and distribution facilities where scalable protection is essential. An interrupt rating of 40 kAIC at 220-240 Vac provides high fault-current withstand and quicker fault clearance. This improves safety, protects downstream equipment, and reduces arc flash risk during peak fault conditions. In practice, engineers can specify this unit to meet plant-wide coordination requirements without oversizing upstream gear. Vertical hanger mounting and the 50% internal grounding option simplify installation and maintenance. The vertical orientation speeds alignment along vertical busways, while the grounding scheme reduces wiring runs and monochromatic grounding issues in complex layouts. This setup aligns with NEC and NEMA expectations for safe, scalable distribution. 100% Neutral support ensures proper handling of multi-wire branch circuits and eliminates uneven neutral loading. Coupled with a plug-in design, it streamlines panel modernization and future reconfigurations. In retrofit projects, this unit minimizes rework and keeps critical feeders compliant with today’s power quality standards. Compliance and certification alignment—UL 857, IEEE Certified, ANSI, CSA—helps procurement teams meet regulatory requirements and pass audits. The plug-in unit is NEMA-compliant and designed for direct integration into existing busway stabs and sections, reducing field engineering time. In operations, you gain repeatable, documented protection across multiple lines. Warranty and support: Eaton’s policy covers one year from installation or 18 months from shipment, whichever comes first, reassuring maintenance planning. With the Pow-R-Way III family, you benefit from documented service lifecycles, easy stocking, and short lead times for replacements.
