Eaton Specification Sheet - ER4X-63N3PR
Enclosed, non-fused rotary disconnect with a pistol-style handle enables rapid, safe isolation of live circuits. The non-fused design reduces the number of components workers must inspect during maintenance, decreasing risk of accidental contact and mis-wiring. This configuration is well-suited for 600 V, 63 A circuits in machine controls, conveyors, and process lines, delivering predictable performance and straightforward field servicing. NEMA 4X enclosure rating provides robust protection against water, dust, and corrosive washdown in harsh environments. The rugged enclosure minimizes corrosion-related downtime and extends service life in outdoor installations or washdown areas, supporting higher uptime and lower replacement costs. For OEMs and integrators, this means fewer enclosure-related design constraints and faster time-to-market for rugged equipment. Compact dimensions and light weight support easier installation in tight spaces, while CE marking confirms compliance with safety standards. The pistol handle enables ergonomic operation during frequent switching, improving operator confidence and safety. The overall design reduces spare parts, accelerates procurement, and enhances maintenance efficiency in production lines.
