Eaton P3BEHD3040G Circuit Breaker Plug-in Unit - 18 kAIC at 240V
Part Number: P3BEHD3040G
Quick Summary
The Eaton P3BEHD3040G circuit breaker plug-in unit provides reliable overcurrent protection for Pow-R-Way III busway. Maintenance and upgrades in live busway installations can create project delays and safety risks. IEEE Certified, CSA Certified, and UL 857 compliance support regulatory goals while delivering dependable protection. As part of Eaton's Pow-R-Way III family, it enables fast plug-in installation, robust grounding, and scalable power distribution. For procurement teams, specifying this unit reduces variance across installs with a single, standardized plug-in design. Engineers benefit from a known performance envelope—40A rating, 18 kAIC at 240V, and 14 kAIC at 480V—while maintaining NEMA compliance. This combination supports faster maintenance cycles, lower total cost of ownership, and safer, compliant operations.

3-Pole, 40A rating paired with a 50% internal grounding design reduces wiring complexity and improves fault path control, delivering faster protection across the Pow-R-Way III busway. This means easier field wiring, reduced installation errors, and a smaller panel footprint, enabling tighter equipment layouts in commercial facilities. The unit's 18 kAIC at 240 VAC and 14 kAIC at 480 VAC handle high fault currents with confidence, limiting damage to downstream equipment and shortening outage times. This performance translates to lower risk during commissioning and a more predictable power profile for critical loads. IEEE Certified, CSA Certified, ANSI, UL 857, and NEMA compliance provide regulatory confidence for industrial environments and data centers alike, supporting safer, audit-ready operations. Compact dimensions — 12.36 in depth, 21.2 in height, 5.43 in width — and a 25 lb weight ensure straightforward mounting within standard Pow-R-Way III frames, with a plug-in design that minimizes wiring and commissioning time. 50% Internal grounding simplifies the grounding scheme, reducing external conductors, while the E-frame configuration ensures interchangeability with other P3 series plug-in units in the same family. Industry practitioners increasingly favor modular, certified protection for busway deployments, and this plug-in unit supports rapid retrofits, scalable protection, and consistent lifecycle performance. Compatibility and installation advantages are built in. The unit is designed for straightforward plug-in installation into Pow-R-Way III busways, minimizing field wiring, reducing commissioning time, and supporting rapid retrofit projects. Its 3-Pole, 40A rating aligns with common distribution feeds in commercial facilities, making it a natural upgrade path for aging busway circuits. Addressing common objections, this plug-in unit offers a clearly defined performance envelope with known interrupt ratings and grounding options, reducing risk during start-up and expansion. The combination of IEEE, CSA, ANSI, and UL 857 certifications, along with NEMA compliance, helps with regulatory audits, supplier qualification, and long-term maintenance planning. Field teams benefit from accessible installation manuals and Eaton datasheets, including the official specification sheet.
