FAQs
When installing the P3BKD3100, ensure compatibility with three-pole busway configurations and KD frame fit. Verify mounting clearance, confirm grounding path (50% integral/housing), and follow Eaton's wiring diagrams to avoid percussive faults. The plug-in design supports quick replacement during maintenance windows, minimizing downtime.
The unit is rated at 100A with interrupt ratings of 65 kAIC at 240V, 35 kAIC at 480V, and 25 kAIC at 600V. This makes it suitable for high fault-current environments and motor-heavy processes. Use these ratings to calculate upstream protection coordination and ensure busway sections stay within safe thermal limits.
Yes. Designed for busway systems with three-pole breakers, it delivers dependable protection for main and feeder circuits. Its grounding option, frame compatibility (K frame), and plug-in convenience support scalable protection schemes in manufacturing, data centers, and process facilities where modular distribution is critical.
The P3BKD3100 carries IEEE Certified, CSA Certified, ANSI, and UL 857 certifications, along with NEMA compliance. These marks demonstrate safety, interoperability, and regulatory alignment, reducing risk during audits and helping procurement meet stringent industry standards for industrial power distribution.
The plug-in design minimizes maintenance downtime by enabling rapid replacement without extensive rewiring. With a defined warranty window (one year from install or 18 months from shipment) and robust fault ratings, facilities can lower total cost of ownership through predictable service intervals, fewer cabinet removals, and improved uptime metrics.
