The 3‑pole, 40A circuit breaker plug-in unit delivers rugged protection for mid-range loads on Pow-R-Way III busways. By matching the E frame design to this busway platform, maintenance crews benefit from straightforward replacement and standardized field service. In industrial settings, this translates to faster swap-outs during outages and reduced downtime, cutting project timelines and labor costs. 100% Neutral ensures balanced phase loading and accurate fault signaling across the distribution network. The plug-in unit maintains neutral integrity even in tight spaces, which improves protection coordination and reduces nuisance tripping in multi-branch configurations. Operators gain consistent performance across multiple units in multi-zone installations. With an 18 kAIC interrupt rating at 240 Vac and 14 kAIC at 480 Vac, the device handles short-circuit events without cascading faults on the busway. This level of rating supports safer startup sequences and aligns with the robustness expected in data centers and heavy manufacturing lines. Engineers can rely on predictable fault handling during software-controlled start sequences. Grounding options include 50% integral/housing grounding to simplify chassis design and installation. These features help achieve compliant grounding schemes while keeping enclosure footprints compact in crowded substation rooms. Fewer field adjustments during commissioning speed up project timelines. Certifications cover IEEE, CSA, ANSI, UL 857, and NEMA compliance, providing regulatory confidence for North American installations. The unit’s compact external dimensions and 25 lb weight help installers plan space and mounting hardware accurately, reducing freight and onsite handling. This also supports standard service contracts by simplifying parts stocking. Compatibility and installation advantages extend to modular busway systems, enabling scalable protection as load and plant layouts change. Operators appreciate quick-field adaptability and reduced wiring complexity compared with traditional panel-based solutions. System integrators report lower total cost of ownership when expanding to additional feeds.

FAQs
Yes. The P3BEHD3040N is a 3-pole, 40A plug-in unit designed to fit Eaton Pow-R-Way III busway configurations. It uses an E frame, weighs 25 lb, and occupies a footprint compatible with the busway housing. With 50% integral grounding and 100% neutral, it aligns with typical field wiring and grounding practices, enabling straightforward field replacement and quick commissioning.
The device provides 18 kAIC at 240 VAC and 14 kAIC at 480 VAC. This means it can interrupt high fault currents without tripping or causing cascading faults within the busway network. For 240 V systems, it offers higher fault current capacity, while at 480 V the rating remains robust for industrial loads, supporting reliable startup and protection coordination.
Industries with modular busway distribution benefit most, including manufacturing, data centers, and process automation facilities. It supports scalable protection in multi-zone, high-reliability environments where fast replacement, 100% neutral balance, and compliant wiring are critical to uptime and safety.
The P3BEHD3040N carries IEEE Certified, CSA Certified, ANSI, and UL 857 certifications and is NEMA compliant. These certifications ensure compliance with North American safety and performance requirements, simplifying procurement and regulatory approvals for industrial facilities.
Plug-in design enables rapid replacement with minimal downtime, reducing maintenance windows. The 25 lb unit is easy to handle on-site, and modularity supports scalable expansion with fewer wiring changes. Over time, this translates to lower total cost of ownership and faster project turnarounds compared with traditional panel-based solutions.
