Three-pole K-frame design provides robust three-phase protection while maintaining compact integration with Pow-R-Way III busways. This translates to fewer nuisance trips and easier coordination with upstream protection, improving line availability in critical production cells. In practice, technicians benefit from consistent breaker characteristics during commissioning and startup of new lines. 100% Neutral capability and flexible grounding options reduce neutral-related fault risk and simplify grounding schemes in mixed-voltage environments, lowering wiring complexity and material costs. Interrupt ratings of 200 kAIC at 240 VAC, 100 kAIC at 480 VAC, and 50 kAIC at 600 VAC deliver protection for high-energy faults, helping meet NEC/NEMA requirements and supporting safe shutdown in demanding environments. Plug-in design enables quick replacement and streamlined maintenance within dense busway racks, while compatibility with Pow-R-Way III components minimizes design risk. With a 150 A rating and K-frame geometry, this unit supports scalable protection for growing facilities, reducing downtime and lifecycle costs. Real-world industry use shows faster changeouts in automotive, packaging, and data-center environments due to standardized interfaces and proven Eaton protection technology.

FAQs
Begin with de-energizing the panel and confirming busway compatibility. Mount the P3BKDC3150N as a three-pole, K-frame breaker within the Pow-R-Way III housing, align with busway feeders, connect neutral to the 100% neutral terminal, and secure the integral or housing grounding as required. Verify proper torque, perform insulation and continuity checks, and test interlocks and trip settings before returning power to service.
The unit is rated for 150 A with interrupt ratings of 200 kAIC at 240 VAC, 100 kAIC at 480 VAC, and 50 kAIC at 600 VAC. It supports 100% neutral operation and offers 50% integral or housing grounding. It is a three-pole breaker designed for busway protection, aligning with NEMA and ANSI requirements.
Yes. The 150 A three-pole K-frame design with substantial interrupt ratings provides robust protection for dense busway configurations. Its plug-in format simplifies maintenance in compact racks, reducing downtime during replacements and upgrades while maintaining coordination with upstream protection devices.
The unit carries UL 857, IEEE Certified, CSA Certified, and ANSI certifications, with NEMA compliance noted for compatibility with standard industrial installations. These certifications assure safety, interoperability, and regulatory alignment across diverse facilities.
Eaton provides a warranty per policy 25-000, typically one year from installation or eighteen months from shipment, whichever occurs first. This coverage supports replacements and technical guidance, helping protect uptime and enabling proactive maintenance planning for power distribution in busway systems.
