Eaton Specification Sheet - ER4-80N3PR
Enclosed protective architecture reduces arc flash exposure and shields live components, improving operator safety and equipment longevity in control panels operating in dusty or wet environments. This leads to lower risk, shorter maintenance windows, and compliant performance in automation installations. Non-fused configuration simplifies control schemes, reduces spare parts inventories, and accelerates commissioning, delivering faster time-to-value for retrofits and new builds in manufacturing environments. A pistol-style handle enables ergonomic, one-handed operation, enhancing safety during isolation sequences and decreasing manual effort for technicians working in confined spaces. The 600 V, 80 A rating paired with a NEMA 4 enclosure supports both indoor and outdoor installations, ensuring reliable performance across temperature and humidity swings in food processing, water treatment, and outdoor equipment applications. CE marking and Bussmann series compatibility streamline regulatory compliance and procurement workflows, while the compact footprint and simple mounting options shorten installation timelines in tight enclosures and switchgear rooms. This combination delivers measurable ROI through reduced downtime, safer operations, and easier maintenance planning for industrial protection projects.
