FAQs
The P3BNW3800LSIGN is designed for plug-in integration into Pow-R-Way III busway configurations, with a three-pole N-frame footprint and dedicated mounting provisions. Plan for a 138 lb module in a compatible enclosure, ensure space for the 19.65 in depth, 10.15 in width, and 45.89 in height, and verify alignment with busway connectors and neutral/ground paths for safe, code-compliant installation.
Key ratings include 800 A amperage, with interrupt ratings of 85 kAIC at 220-240 VAC, 50 kAIC at 380-415 VAC, and 20 kAIC at 660-690 VAC. These values determine fault-current withstand and clearing speed across voltages, enabling proper protection coordination with downstream devices and minimizing damage during faults in mixed-voltage facilities.
Yes. The unit is specified as three-pole with N-frame design and Pow-R-Way III compatibility, making it suitable for NW busway feeders. Its LSIG option supports efficient integration, and the 100% neutral design helps maintain balanced loading in multi-pole busway layouts commonly found in large facilities.
The product carries UL 857 certification, CSA certification, and ANSI/IEEE recognition, along with NEMA compliance. These certifications confirm safety, interoperability, and regulatory adherence for industrial electrical installations, simplifying procurement, installation approvals, and ongoing compliance audits in regulated environments.
The unit’s robust build (N-frame, three-pole) and LSIG capability reduce wiring complexity and installation time, lowering labor costs. A one-year Eaton warranty and UL/CSA/IEEE certifications support predictable maintenance planning and asset longevity, contributing to reduced downtime and a favorable total cost of ownership over the equipment lifecycle.
