Eaton ER3R-600N3PB Enclosed Rotary Disconnect - NEMA3R
Part Number: ER3R-600N3PB
Quick Summary
Eaton ER3R-600N3PB enclosed rotary disconnect switch provides reliable isolation for electrical feeders in industrial and commercial panels. Operators often contend with nuisance fuse faults and inadvertent energization, which can trigger costly downtime. This unit carries CE marking and a rugged NEMA 3R enclosure, meaning it stands up to dust, moisture, and outdoor or washdown environments. Designed for compatibility with the Eaton Bussmann series, it supports straightforward installation and safer maintenance in motor control centers, service panels, and equipment disconnects, helping facilities reduce outage duration and improve safety. The pistol handle enables quick, controlled operation, while the non-fused design minimizes interruptions during commissioning and routine maintenance.

Eaton Specification Sheet - ER3R-600N3PB
Non-fused, enclosed design provides simple, maintenance-friendly isolation without spare fuse management. This reduces fuse-related outages, minimizes accidental energization, and lowers spare parts inventory for plants with frequent interlocks and commissioning. It is ideal for motor control centers (MCCs), service disconnects, and equipment enclosures where quick, reliable de-energization is essential. 600 V and 600 A ratings position this unit for feeding large feeders and moderate to heavy-duty equipment. The robust rating supports one-disconnect protection per line or feeder stage, simplifying electrical protection schemes and reducing panel footprint by consolidating functions. It pairs well with Eaton Bussmann series components for streamlined procurement and compatibility across standard electrical protection and circuit control applications. NEMA 3R enclosure provides outdoor-ready protection against dust, water, and weather exposure, enabling both indoor and outdoor installations. Combined with CE marking, the switch meets global safety and reliability standards while resisting typical industrial contaminants. This enclosure design minimizes corrosion risk and helps maintain performance in stacked racks, outdoor switchgear, or exposed panel boards. Pistol-style operating handle enhances ergonomics, enabling controlled, confident actuation with reduced operator fatigue. The non-fused configuration eliminates fuse handling during routine operations, further improving safety and uptime. The unit’s compact form and clear labeling support fast, compliant maintenance in high-safety environments such as process lines and packaging systems. Compatibility with the Eaton Bussmann series promotes straightforward sourcing and integration within existing electrical protection architectures. CE marking reinforces global admissibility in compliant facilities, while the overall design aligns with common installation practices for panelboards, MCCs, and service disconnects. This combination translates to lower project risk, faster commissioning, and longer service intervals in industrial plants.
