The P3BKD3400G provides a 400A amperage rating, enabling a single protective device to serve substantial busway loads, which reduces overall panel count and simplifies layout planning. This directly translates to faster commissioning, easier spare-part management, and lower total installed cost for industrial power systems. In practice, the three-pole KD/K-frame design supports straightforward field upgrades and modular replacement in busy production lines, minimizing downtime during maintenance. The unit’s plug-in form factor enables quicker swaps without extensive wiring work, improving safety and reliability in motor control centers and distribution rooms. Its high interrupt ratings—65 kAIC at 240 VAC, 35 kAIC at 480 VAC, and 25 kAIC at 600 VAC—provide robust fault protection for high-energy facilities, reducing the risk of collateral equipment damage. Grounding options at 50% internal simplify grounding schemes in complex busway layouts, while the physical footprint (13.29 in deep, 34.41 in high, 7.79 in wide) and 53 lb weight support precise fitment in tight spaces. Together with industry certifications and a standard one-year warranty, this unit delivers predictable performance, regulatory compliance, and long-term maintenance peace of mind.
