FAQs
To install, power off the system, verify busway compatibility, and align the plug in unit with the busway interface. Secure the mounting points, connect line and load conductors per the spec sheet, and torque connections to Eaton guidelines. Confirm 90 A rating and 18 kAIC at 240 VAC are suitable for the site fault current. Finally, verify neutral and grounding configurations and perform a functional test after restoration.
Key ratings include 90 A amperage, 18 kAIC at 240 VAC and 14 kAIC at 480/600 VAC. The unit supports 100 percent neutral and 50 percent internal grounding. Certifications cover ANSI IEEE, UL 857, CSA, and NEMA compliance, ensuring regulatory alignment for both industrial and commercial installations.
Yes. The device is rated for 240 VAC with 18 kAIC interrupt capability and also supports 480 VAC and 600 VAC with 14 kAIC ratings, making it versatile for mixed voltage busway systems. Its three pole design and F frame support reliable protection across these common industrial distributions.
The unit measures 12.36 in in depth, 21.2 in in height, and 5.43 in in width, with a weight of 25 lb. It is designed as a plug in module for Pow-R-Way III busway systems. Ensure adequate clearance for cooling and removal, and plan for neutral and grounding terminations, which are 100 neutral and 50 internal ground as specified.
The unit comes with a one year warranty and uses standardized Eaton components, reducing maintenance complexity and spare part diversity. Its plug in design minimizes downtime during substitutions, while high interrupt ratings protect critical loads, lowering the risk of unscheduled outages and driving improved uptime and return on investment in retrofit projects.
