FAQs
The P3BKDB3400N is designed for seamless integration with Pow-R-Way III busway assemblies. It uses a three-pole, K-frame configuration compatible with 70-400 A ranges and busway plug-in connections, which minimizes retrofit complexity. This compatibility reduces field wiring, speeds up installation, and ensures consistent performance across new and existing installations while maintaining UL 857 and CSA IEEE certifications.
Key specifications include a 400A amperage rating, interrupt ratings of 65 kAIC at 240 Vac, 35 kAIC at 480 Vac, and 25 kAIC at 600 Vac, 100% Neutral, and 50% Integral/Housing grounding. Dimensions are 13.29 in length, 34.41 in height, and 7.79 in width, with a shipping weight of 53 lb. These specs support reliable protection in medium- to high-current busway circuits.
Yes. The unit is UL 857 certified, CSA Certified, IEEE Certified, and ANSI compliant, with NEMA guidance for electrical products. This certification suite supports regulatory acceptance in industrial facilities, reduces validation time for compliance audits, and provides assurance that the plug-in unit meets stringent safety and performance standards for busway distribution.
The plug-in design simplifies field installation by reducing terminal wiring and enabling quick replacement or upgrade within existing busway footprints. Its 100% Neutral and 50% integral grounding support straightforward grounding schemes, improving fault tolerance. Regular maintenance is facilitated by standardized Eaton components, while warranty terms help manage lifecycle costs and minimize downtime during component swaps.
Implementing the P3BKDB3400N can reduce stuck-open faults and unplanned downtime through high interrupt ratings and robust busway protection. The plug-in configuration shortens commissioning time, minimizing labor costs during installation. Combined with its certifications and durable K-frame construction, facilities can expect lower maintenance expenses, improved safety, and a faster path to scalable power distribution upgrades, contributing to a favorable total cost of ownership.
