Feature → Business Impact → Application: The P3BFDB3040N delivers 40A protection with an 18 kAIC interrupt rating at 240 Vac (14 kAIC at 480/600 Vac), enabling robust fault interruption for busway-fed loads and reducing equipment damage and downtime in busy production lines. Application: ideal for Eaton Pow-R-Way III busway systems in manufacturing cells and distribution centers. Feature → Fast service → Installation efficiency: As a plug-in, three-pole, F-frame design, it enables quick field replacement with minimal panel downtime. Application: supports rapid maintenance in high-uptime environments, improving overall line availability. Feature → Grounding and neutral flexibility → Safety and compliance: 100% Neutral with 50% Integral/Housing grounding simplifies bonding schemes and enhances regulatory alignment. Application: essential for control circuits and safe operation in mixed-load power distribution. Feature → Certification stack → Regulatory readiness: NEMA Compliant with UL 857, CSA Certified, IEEE Certified, and ANSI listings provide confidence in safety and reliability. Application: suitable for regulated North American facilities and OEM panel builds. Feature → Physical footprint and warranty → Total cost of ownership: Dimensions of 12.36 in L × 21.2 in H × 5.43 in W and 25 lb weight support compact integration, while the one-year warranty (or 18 months from shipment) reduces risk. Application: procurement planning for modular, serviceable busway protection.
