Eaton P3BKW3400GNSP Pow-R-Way III circuit breaker plug-in unit - 85 kAIC

Feature: Sprinkler-proof plug-in design enables safe deployment in environments with fire suppression systems. Business Impact: reduces risk of arcing, corrosion, and nuisance trips during sprinkler activation, while speeding maintenance because replacements are plug-and-play. Application: busway protection in industrial facilities where uptime is mission-critical, such as manufacturing plants and data centers. This design also minimizes retrofit complexity when upgrading existing Pow-R-Way III installations. The plug-in unit is compatible with standard KW frame ranges and supports quick field changes. Feature: Three-pole, K-frame, 400 A rating provides robust power distribution within a compact footprint. Business Impact: handles heavy current without sacrificing protection or space, improving panel density and reducing enclosure costs. Application: new builds and retrofits that rely on Pow-R-Way III plug-in units to feed large motors and feeders across a busway network. The K-frame design ensures consistent mechanical alignment with Eaton's modular busway architecture. Feature: High interrupt ratings across voltage ranges—85 kAIC at 220-240 VAC, 45 kAIC at 380-415 VAC, and 20 kAIC at 660-690 VAC—give consistent fault clearance. Business Impact: limits fault propagation, protects upstream equipment, and lowers maintenance costs due to fewer downstream damages. Application: multi-voltage industrial plants where different circuits share the same busway infrastructure. These ratings align with IEC and NFPA guidelines in many regions. Feature: 100% Neutral and 50% Internal Ground options provide flexible grounding and neutral distribution. Business Impact: simplifies coordination with downstream protection schemes and reduces grounding-related troubleshooting. Application: standard Pow-R-Way III panels and busways that require predictable neutral paths for harmonics control and safety compliance. This flexibility supports custom grounding schemes for complex plant layouts. Feature: Certifications, compliance, and warranty—IEEE, UL 857, CSA, ANSI, and NEMA Compliant, plus a one-year warranty (18 months from shipment per Eaton policy). Business Impact: streamlines regulatory approvals, improves procurement confidence, and protects investment through coverage during initial installation and operation. Application: procurement and field service teams seeking reliable, code‑compliant protection for critical busway circuits. Documentation and datasheets—Specification Sheet and policy SP03000001e—support audits and long-term maintenance planning.
