The 3-pole, 350 A protection rating enables scalable power distribution across Eaton Pow-R-Way III busways, delivering higher fault tolerance and reduced risk of cascading outages in mid- to large-size facilities. This translates to improved uptime and fewer emergency repairs during peak production periods in manufacturing environments. The interrupt ratings of 65 kAIC at 240 V, 35 kAIC at 480 V, and 25 kAIC at 600 V provide rapid fault clearing, minimizing arc energy exposure and equipment damage for critical processes in data centers and process plants. With a 50% integral grounding option, installation is simplified and grounding pathways are streamlined, reducing commissioning time and potential miswiring during field wiring. The K-frame, 3-pole design fits standard busway configurations, enabling quick replacement and modular expansion without extensive rewiring. Compliance with IEEE, CSA, ANSI, and UL 857 supports regulatory acceptance and supplier qualification, reducing procurement risk. The unit’s dimensions and weight—13.29 in depth, 34.41 in height, 7.79 in width, and 53 lb—facilitate handling, shipping, and fit in constrained mechanical spaces, improving site logistics and installation planning. Engineered for fast field replacement, the P3BKDB3350 minimizes downtime during maintenance windows while enabling scalable protection for evolving facilities and OEM equipment.
