FAQs
The P3BKDB3400G is a 3-pole plug-in unit designed for Pow-R-Way III busway systems, featuring a K-frame and 50% internal grounding. Installation involves mounting the unit onto the busway with proper alignment to the K-frame, connecting grounding per internal grounding guidelines, and ensuring compatibility with regional standards (NEMA, IEEE, CSA, ANSI, UL 857). Follow Eaton’s datasheet and your panel manufacturer’s integration practices for a safe, code-compliant installation.
The P3BKDB3400G provides 65 kAIC at 240 VAC, 35 kAIC at 480 VAC, and 25 kAIC at 600 VAC. This range supports robust fault clearance for main feeders and motor loads across common industrial voltages, reducing the likelihood of downstream damage and improving ride-through during faults, which translates to safer operation and reduced unplanned downtime.
Yes. The unit carries IEEE, CSA, ANSI, and UL 857 certifications and is NEMA compliant, enabling safe use across multiple regions. This reduces the need for separate variants when expanding operations internationally and simplifies supplier and maintenance workflows while ensuring regulatory compliance.
The 50% internal grounding option streamlines grounding paths by integrating a substantial portion of the grounding within the unit itself. This reduces external grounding hardware, simplifies wiring, and minimizes potential ground loops, improving reliability and cutting installation time in dense panel cabinets.
The modular design enables rapid unit swaps and scalable protection without full-panel replacements, reducing downtime during maintenance and upgrades. With a 400 A rating and high interrupt capability, you gain fault tolerance while limiting spare-part inventories. Over time, this translates to lower maintenance costs, faster capacity expansion, and improved overall equipment effectiveness (OEE).
