The P3BEHD3020 uses a three-pole, E-frame design to provide reliable protection for three-phase busway circuits. This configuration delivers consistent interruption performance with a 20A amperage rating and an 18 kAIC interrupt capacity at 240 Vac, ensuring fast fault clearance without impacting adjacent feeders. In practice, this makes it ideal for electronics-heavy manufacturing floors and distribution panels where duty cycles are high and uptime matters. Grounding and installation: The unit supports 50% integral or housing grounding, simplifying site grounding strategies. This flexibility reduces installation steps and improves fault-path clarity during maintenance, especially in older facilities with mixed grounding practices. For contractors, plug-in mounting speeds service replacements and minimizes downtime during line upgrades. Compliance and safety: UL 857, IEEE, ANSI, and CSA certifications align with stringent electrical codes, reducing regulatory risk for new builds and retrofits. NEMA compliance further supports rugged operation in industrial environments. This combination gives OEMs and end users confidence during audits and inspections. Physical footprint and handling: With dimensions of 12.36 in length, 21.2 in height, and 5.43 in width, and weighing 25 lb, the P3BEHD3020 fits into compact spaces and manageable shipping totes. The plug-in design simplifies sourcing, inventory planning, and field swaps by minimizing mounting hardware. These attributes help steady project timelines and reduce warehousing costs. Performance consistency and maintenance: The 20A rating paired with 18 kAIC at 240 Vac and 14 kAIC at 480 Vac delivers predictable fault interruption across typical industrial loads. Regular operating temperatures, combined with reliable materials and Eaton's engineering discipline, translate into longer service intervals. Maintenance teams report fewer nuisance trips and quicker diagnostics in routine testing. Compatibility and lifecycle value: Engineered for seamless integration with Pow-R-Way III busway systems, the plug-in unit supports fast replacements without specialized tools. The one-year warranty from installation or 18 months from shipment provides a clear cost-of-ownership baseline. For modernization projects, this translates into lower total cost of ownership and faster time-to-value.

FAQs
The P3BEHD3020 is designed for straightforward plug-in installation within Eaton Pow-R-Way III busway infrastructures. First, confirm busway alignment and remove any protective covers. Then slide the plug-in unit into the designated slot, align with mounting features, and engage the grounding option as required (50% integral or housing). Finally, verify electrical continuity and perform a brief functional test to confirm correct trip coordination with adjacent breakers. This process minimizes downtime and reduces the risk of mis-wiring thanks to standardized Eaton connectors and documented installation guidance.
The P3BEHD3020 is a three-pole, E-frame device rated at 20 A. It provides an 18 kAIC interrupt capacity at 240 Vac and 14 kAIC at 480 Vac, enabling rapid fault interruption for typical industrial loads on busway circuits. This combination ensures reliable protection for mid-current distribution panels while maintaining coordination with upstream protective devices. Suitable applications include manufacturing lines and critical plant sections where uptime is essential.
Yes, the P3BEHD3020 is UL 857 listed. In addition to UL 857, the unit carries IEEE Certified, ANSI, and CSA certifications, reflecting compliance with key national and international electrical safety standards. This certification set supports audits, regulatory compliance, and acceptance in projects requiring rigorous safety and performance documentation for electrical protection equipment.
The unit offers 50% integral or housing grounding, allowing flexibility to match site grounding practices. This reduces the need for additional grounding hardware and simplifies retrofits in facilities with mixed grounding schemes. Choosing the appropriate grounding option during installation improves fault-path clarity and enhances overall system safety without complicating panel layouts.
Eaton provides a warranty of one year from the date of installation or eighteen months from shipment, whichever occurs first. This warranty supports lifecycle cost planning and reduces procurement risk during capital projects. For modernization programs, the warranty, along with UL and IEEE certifications, helps justify total cost of ownership and maintenance planning.
