FAQs
To install the P3BKD3400, verify busway compatibility, mount the plug-in unit into the KD frame, and connect conductors per the busway installation instructions. Ensure grounding is configured to the 50% integral/housing option, and confirm the unit's three-pole configuration fits the designated panel footprint. Finally, perform a functional checkout and insulation resistance test to validate proper operation.
The P3BKD3400 provides 65 kAIC at 240 VAC, 35 kAIC at 480 VAC, and 25 kAIC at 600 VAC. These ratings enable effective protection for high‑fault scenarios across common industrial voltages, reducing the risk of equipment damage and unplanned downtime.
Yes. With a 400A rating and high interrupt ratings, the P3BKD3400 is well-suited for high-density motor feeders and process-load protection in busway environments. Its three-pole, KD plug-in design facilitates rapid deployment in demanding manufacturing and processing facilities while maintaining regulatory compliance.
The unit carries IEEE certification, UL 857 listing, CSA certification, and ANSI compliance. These certifications support safe operation, interoperability with other equipment, and streamlined approvals in industrial control environments.
The P3BKD3400 comes with Eaton’s warranty policy: one year from installation or eighteen months from shipment, whichever occurs first. Regular inspection for signs of wear, proper grounding, and periodic functional checks help maintain reliability and minimize unforeseen maintenance costs.
