Three-pole, three-wire design aligns with standard Pow-R-Way busway configurations, simplifying wiring and improving fault isolation. Business impact: faster commissioning, fewer wiring errors, and improved line reliability. Application: ideal for factory floor distribution panels using busway segments. The unit delivers 65 kAIC at 240 VAC, 35 kAIC at 480 VAC, and 25 kAIC at 600 VAC, providing high fault-current protection for critical loads. Business impact: enhanced safety margins and reduced downtime during faults. Application: data centers and manufacturing lines with diverse load profiles. Grounding options include 50% integral or housing grounding, giving installers flexibility to meet site grounding practices and standards. Business impact: simplified compliance and reduced installation time. Application: facilities requiring adaptable grounding strategies for modular busway assemblies. With a 500 A amperage rating at 600 V, the device supports substantial power distribution while keeping a compact footprint. Business impact: lower total cost of ownership through fewer components and simpler maintenance. Application: mid-to-large industrial feeders. The Pow-R-Way III design enables plug-in enclosure compatibility, reducing field wiring length and simplifying future reconfigurations. Business impact: easier upgrades and scalable electrical infrastructure. Application: evolving plant layouts and expansion projects. Certifications to note include ANSI, CSA, and IEEE, along with NEMA compliance, supporting regulatory alignment and safer operation. Business impact: risk mitigation and smoother audits. Application: any environment requiring rigorous standards conformance. Warranty coverage (one year from installation or eighteen months from shipment) provides risk reduction during early adoption and deployment phases. This support reduces unplanned downtime while you validate system performance. Application: project rollouts and service windows where reliability matters.

FAQs
To install the P3BLD3500, first verify busway compatibility and mount the plug-in unit onto the designated Pow-R-Way enclosure. Connect three poles to the three-wire busway per the standard wiring diagram, and establish grounding via the 50% integral/housing option. Torque critical connections to spec and perform a control circuit test to confirm proper trip operation under nominal load conditions. This approach reduces commissioning time and minimizes field wiring errors.
The P3BLD3500 provides 500 A at 600 V with interrupt ratings of 65 kAIC at 240 VAC, 35 kAIC at 480 VAC, and 25 kAIC at 600 VAC. These ratings support reliable protection for moderate to high-current busway feeders, helping maintain service continuity during fault events while meeting standard utility and equipment protection requirements.
Yes. The unit’s three-pole, three-wire configuration, 600 V rating, and high interrupt ratings make it well-suited for data centers, manufacturing lines, and other facilities using busway power distribution. Its plug-in design accelerates installation and simplifies future upgrades, which is especially valuable in spaces with tight land for modular protection and scalable protection schemes.
The P3BLD3500 is UL 857 listed and certified to ANSI, CSA, and IEEE standards, with NEMA compliance. These certifications assure regulatory alignment, safer operation in industrial environments, and smoother audits and qualification processes for critical power distribution equipment.
The unit carries Eaton’s warranty of one year from installation or eighteen months from shipment, whichever comes first. For best ROI, schedule periodic inspection of grounding connections, verify torque on terminations, and monitor insulation and trip performance. Regular maintenance reduces unexpected outages and extends the service life of busway protection schemes.
