Eaton ER04-100CF3PR Enclosed Rotary Disconnect - NEMA 4

Enclosed rotary disconnect design provides robust isolation while keeping live components shielded from dust, moisture, and incidental contact in demanding industrial environments. This feature directly reduces arc-flash exposure and maintenance risk, enabling safer maintenance windows, faster turnarounds, and improved personnel safety. For panel designers and technicians, the enclosure simplifies safety justification, aligns with common industrial safety standards, and supports compliant lockout/tagout practices during service. CF fuse type compatibility ensures fast, selective protection without requiring a wholesale switchgear redesign or special wiring schemes. It simplifies spare parts inventory by aligning with the Bussmann CF family, reducing stocking complexity and shortening downtime during fuse replacements. In field applications, this compatibility supports predictable performance across diverse motor feeders, control circuits, and distribution panels. Rated for 600 V and 100 A in a three-pole configuration, ER04-100CF3PR supports typical three-phase motor circuits, power feeders, and process loads with confident protection. The rating delivers reliable operation while maintaining a compact footprint that eases panel integration and reduces wasted cabinet space. Engineers also value the standard pistol handle for ergonomic, one-hand operation under load, minimizing operator fatigue. NEMA 4 enclosure provides weather and dust resistance suitable for indoor and outdoor installations, including damp or wash-down environments, which reduces additional enclosure requirements. CE marking confirms compliance with European safety standards, facilitating global deployment and supplier diversity in procurement. The rugged enclosure design contributes to longer service intervals and lower maintenance costs in harsh environments. Pistol handle enables ergonomic operation and quick, safe disconnection during routine maintenance or fault isolation, even with gloved hands. The unit dimensions—11.8 in depth, 10.8 in height, and 9.84 in width—with a 6 lb weight support straightforward mounting in compact switchgear or retrofit projects and simplify shipping logistics. This combination delivers reliable, cost-effective protection for a wide range of industrial control panels while enabling fast commissioning and reduced total cost of ownership.
