Eaton P3BKDC3400N Pow-R-Way III plug-in breaker - UL 857
Part Number: P3BKDC3400N
Quick Summary
The Eaton Pow-R-Way III circuit breaker plug-in unit protects busway systems by interrupting faults in three-pole configurations. Installing in high-current environments can be challenging due to space constraints, grounding options, and integration with housing. IEEE certified, CSA certified, and UL 857 listings accompany ANSI recognition, delivering reliability and safety under rigorous standards. Designed for busway protection, it supports a 400 A rating with high interrupt capability, helping minimize downtime and maintenance costs. In practice, the 100% neutral and 50% integral or housing ground options simplify wiring and speed field upgrades. This combination of ratings and compliance makes it a practical, long-term solution for industrial power distribution.

FAQs
Yes. The P3BKDC3400N is a three-pole, K-frame plug-in unit designed specifically for Eaton Pow-R-Way III busway configurations. With a 13.29 in depth, 34.41 in height, and 7.79 in width, it aligns with standard busway footprints and supports 400 A service with 100% neutral and 50% integral grounding for straightforward field integration.
The unit provides a 400 A amperage rating and an interrupt rating of 200 kAIC at 240 VAC, 100 kAIC at 480 VAC, and 50 kAIC at 600 VAC. This combination ensures strong fault current protection across typical industrial busway applications, reducing equipment damage and downtime during faults.
Ideal for industrial power distribution in manufacturing plants, processing facilities, and energy-intensive environments, the P3BKDC3400N protects busway feeders and distribution segments. Its three-pole design, grounding options, and neutral capability support reliable protection in challenging layouts and retrofit projects.
The unit is IEEE certified, CSA certified, ANSI approved, and UL 857 listed, with NEMA compatibility. These certifications help meet industry and regulatory requirements, simplify audits, and support safer, compliant installations across regulated sectors.
Eaton offers a one-year warranty from the installation date or eighteen months from shipment, whichever occurs first. This policy provides protection against manufacturing defects and supports faster return-to-service during retrofit projects or new installations.
