FAQs
Installation begins with confirming busway compatibility and ensuring power is isolated. The plug-in unit mounts into the Pow-R-Way III busway segment using the documented mounting provisions for the F-frame. Verify grounding options (50% integral/housing) and connect conductors per the 3-pole configuration. After securing the unit, perform a system integrity check and verify insulation, alignment, and clearance to prevent arcing or overheating during operation.
The unit is rated for 45A with a 3-pole arrangement. It provides an interrupt rating of 100 kAIC at 240 VAC and 480 VAC, and 25 kAIC at 600 VAC, enabling robust fault protection for typical industrial and data-center busway loads while maintaining safe interruption at higher fault currents.
This Eaton module carries IEEE Certified, CSA Certified, ANSI, and UL 857 listings, along with NEMA compliance. These certifications confirm safety, performance, and reliability across diverse industrial applications and regulatory environments.
The unit measures approximately 12.36 in in depth, 21.2 in in height, and 5.43 in in width, and weighs around 25 lb. It is designed for 3-pole, F-frame protection and supports 50% integral grounding. Plan for adequate space in the electrical enclosure and ensure grounding conductors are properly routed to meet NCR and local codes.
By enabling plug-in protection within Pow-R-Way III busways, this unit minimizes downtime during maintenance and simplifies field replacements. Its high interrupt ratings and certified safety make it a cost-effective choice for protecting critical loads, reducing boilerplate rework, and accelerating project timelines for facilities investing in scalable, compliant power-distribution protection.
