FAQs
Is the P3BKD3350N compatible with Pow-R-Way III busways? Yes. It is a three-pole KD plug-in unit designed to fit majority Pow-R-Way III busway sections. Typical installation steps involve aligning with the busway channel, securing the device with the KD mounting pattern, and connecting to the bus bars. The unit’s dimensions (13.29 in depth, 34.41 in height, 7.79 in width) and 53 lb weight help you plan for supporting structures and clearances in standard industrial enclosures.
What ratings define the device’s protection? The P3BKD3350N provides 350 A amperage with interrupt ratings of 65 kAIC at 240 VAC, 35 kAIC at 480 VAC, and 25 kAIC at 600 VAC. This means robust fault clearing for typical industrial loads, motor drives, and panel feeders while maintaining system integrity during fault events. Neutral is 100% available, and grounding can be 50% integral or housing, depending on the installation needs.
Yes, the P3BKD3350N is designed for general industrial use and is compliant with multiple standards. It carries IEEE Certified, UL 857 listed, CSA Certified, and is NEMA compliant, providing regulatory assurance for varied environments. For humid or harsh environments, ensure proper enclosure rating and installation practices while leveraging its grounding options to maintain safe operation.
Warranty coverage follows Eaton policy 25-000: one year from the date of installation or eighteen months from shipment, whichever occurs first. This protection covers manufacturing defects and ensures access to Eaton support resources for troubleshooting, replacements, and guidance on commissioning within Pow-R-Way III busway configurations.
The unit delivers reliable protection with a plug-in design that reduces installation time and panel footprint. Its high interrupt rating minimizes downtime during faults, while 100% neutral and flexible grounding improve safety and compliance. In practice, this translates to lower lifecycle costs, easier maintenance, and faster project sign-off in manufacturing and processing facilities.
