Eaton P3BHFW3040JGN Breaker Plug-in Unit - NEMA Compliant
Part Number: P3BHFW3040JGN
Quick Summary
Eaton Pow-R-Way III circuit breaker plug-in unit provides reliable overcurrent protection for busway power distribution. Engineers and maintenance teams often struggle with fast, compliant protection in compact busway footprints, which can drive downtime. This model carries UL 857, ANSI/IEEE certifications, and CSA eligibility with NEMA compliance to support broad North American use. It features 100% neutral and 50% internal grounding, simplifying wiring and improving fault isolation, delivering measurable cost savings. The compact footprint fits busy installations, while 40 A protection and high interrupt ratings help keep systems up and running. Additional benefits come from quick field replacement, compatibility with existing Eaton busway components, and a clear path to scalable protection as plant layouts evolve.

Feature: Three-pole F-frame plug-in design supports three-phase protection for Pow-R-Way III busway systems. Business Impact: Ensures synchronized protection across all phases, reducing the risk of arc flash and unbalanced loads, while enabling faster installation. Application: Ideal for new builds and retrofits in manufacturing lines where three-phase power distribution is critical. Feature: Amperage Rating of 40A. Business Impact: Aligns protection with moderate-capacity feeders, minimizing nuisance trips and optimizing panel loading. Application: Suitable for mid-range busway feeders in processing facilities. Feature: Interruption ratings of 100 kAIC at 220–240 VAC, 70 kAIC at 380–415 VAC, and 14 kAIC at 660–690 VAC. Business Impact: Provides robust fault-current handling across multiple voltage classes, reducing downtime from fault events and simplifying coordination studies. Application: Essential for mixed-voltage industrial environments. Feature: 100% Neutral option. Business Impact: Ensures balanced phase currents and simplifies neutral conductors in multi-pole busway layouts. Application: Critical in systems with heavy neutral loading or sensitive electronics. Feature: 50% Internal Ground. Business Impact: Improves fault discrimination and reduces wiring complexity by localizing grounding within the unit. Application: Beneficial for installations prioritizing quick fault isolation. Feature: Busway compatibility with Pow-R-Way III. Business Impact: Accelerates installation with plug-in compatibility and reduces field wiring complexity. Application: Broadly applicable to Eaton busway deployments in both new and retrofit projects. Feature: Physical footprint and weight. Business Impact: 12.36 in depth, 21.2 in height, 5.43 in width, and 25 lb weight enable integration into tight enclosures without compromising protection. Application: Suitable for space-constrained switchgear rooms and modular plant layouts. Feature: Certifications and warranty. Business Impact: UL 857, ANSI/IEEE, CSA certifications and NEMA compliance support regulatory adherence; 1-year warranty minimizes lifecycle risk. Application: Essential for procurement specs and asset protection planning.
