Eaton P3BEHD3045GN Circuit Breaker Plug-in - UL 857

The P3BEHD3045GN delivers a 3‑pole, 45A circuit protection within an EHD frame, supporting fault currents of 18 kAIC at 240V and 14 kAIC at 480V. This capability translates to robust protection for critical loads while allowing rapid maintenance interventions without extended downtime. In practice, the higher interrupt rating reduces fault duration and limits collateral damage to adjacent equipment, improving line reliability for manufacturing lines and data-center feeder arrangements. The unit’s grounding configuration, offering 50% internal grounding and 100% neutral, enhances safety by providing predictable fault paths and clean neutrals for sensitive electronics, reducing electrical noise and potential malfunctions in control circuits. For installers, the plug-in format simplifies upgrades and replacements, minimizing field wiring and enabling modular expansion within Pow-R-Way III busway infrastructures. These features collectively improve compliance, ease of retrofits, and lifecycle cost efficiency. The compact dimensions (12.36 in depth, 21.2 in height, 5.43 in width) and a 25 lb weight support straightforward mounting on standard busway supports, enabling scalable protection in compact electrical rooms and restricted service aisles. In real-world deployments, this translates to faster deployment, lower labor costs, and more predictable maintenance windows, especially in high-demand facilities like automation plants and process lines.
