FAQs
The P3BKDB3400GN uses a plug-in, three-pole design built for Eaton busway compatibility. Its K Frame supports 70-400 A integration, with a compact 13.29 in depth and 7.79 in width, simplifying mounting on standard busway stabs. Installation minimizes wiring runs and reduces commissioning time, making retrofit projects and new builds faster and more predictable.
This unit is rated for 400A with interrupt ratings of 65 kAIC at 240 VAC, 35 kAIC at 480 VAC, and 25 kAIC at 600 VAC. It provides 100% Neutral and 50% Internal Ground, along with NEMA compliance and certifications (ANSI UL 857, IEEE, CSA). These specs support reliable fault protection and safe operation in demanding industrial environments.
Yes. Its three-pole, K Frame design and busway compatibility make it ideal for high-density distribution scenarios. The 400A capacity and robust interrupt ratings ensure quick fault clearance, while the plug-in form factor reduces maintenance downtime. This combination is particularly beneficial for manufacturing lines, process industries, and data-center grade power distribution.
The unit carries ANSI UL 857, IEEE Certification, and CSA Certification, with NEMA compliance. These certifications support regulatory audits, interoperability with other devices in the protection scheme, and cross-border deployment in many regions. Maintaining documentation of these certifications aids in compliance verification during inspections.
The plug-in design enables faster field replacement, reducing downtime during maintenance and upgrades. With proven protection ratings and modular busway integration, you can expect lower labor costs, shorter outage windows, and improved system availability. The 1-year warranty (or 18 months from shipment) adds a predictable support framework for lifecycle planning.
