FAQs
Compatibility centers on busway-based power distribution with a three-pole, F-frame design. The unit adheres to ANSI/IEEE and UL 857 standards and features 50% internal grounding, NEMA compliance, and a plug-in form factor that accelerates retrofit projects in space-constrained panels. For best results, verify busway channel dimensions and mounting provisions in the project specs.
Key specs include a 125A amperage rating, three-pole configuration, and interrupt ratings of 65 kAIC at 240 VAC, 25 kAIC at 480 VAC, and 18 kAIC at 600 VAC. These ratings define fault-current withstand and coordination with upstream devices. Consider these values against your facility’s fault current calculations and busway ratings to ensure proper protection.
Yes. Its Pow-R-Way III design is purpose-built for busway installations, offering robust overcurrent protection in a plug-in format. With 125A capacity, high interrupt ratings, and certified compliance (ANSI/IEEE, UL 857, CSA), it supports reliable protection for motors, conveyors, and other heavy loads while enabling modular, scalable protection schemes.
The unit carries ANSI/IEEE certification, UL 857 listing, and CSA certification, plus NEMA compliance. These certifications indicate conformity with recognized safety and performance standards, easing regulatory approvals, supporting cross-site installations, and reducing risk during audits and inspections.
The modular plug-in design reduces installation time and simplifies field replacements, lowering labor costs during upgrades and maintenance. A 125A rating with high fault-current withstand plus a one-year warranty (or 18 months from shipment) from Eaton translates to predictable maintenance expenditures and improved lifecycle value for power distribution investments.
