FAQs
The P3BKDC3300 is a three-pole, K-frame plug-in unit designed for Pow-R-Way III busway installations. It integrates with standard busway accessories, supports 70-400 A frames, and uses a plug-in format to minimize field wiring. This simplifies retrofit projects and reduces commissioning time, making it suitable for expanding manufacturing lines and data center feeds.
This unit provides a 300 A amperage rating with interrupt ratings of up to 200 kAIC at 240 Vac, 100 kAIC at 480 Vac, and 50 kAIC at 600 Vac. The multi-voltage capability supports diverse loads, allowing a single device to protect critical busway segments while maintaining coordination with upstream protection devices.
It carries IEEE Certified, UL 857, ANSI, and CSA certifications, along with NEMA compliance. This combination supports regulatory approvals, safety assurances, and consistent performance across regions, simplifying procurement and audit processes for regulated facilities.
The plug-in design reduces field wiring, speeds up initial installation, and enables rapid replacement or upgrades without disturbing other busway segments. With known dimensions (13.29 in L × 34.41 in H × 7.79 in W) and a 53 lb weight, on-site handling is straightforward, minimizing downtime during proactive maintenance or fault recovery.
Eaton provides a standard warranty per policy 25-000: one year from installation or 18 months from shipment, whichever occurs first. This, combined with a robust aftermarket support ecosystem, helps protect total cost of ownership and improves ROI through predictable maintenance planning and readily available spare parts.
