Eaton ER3R-30N3PB Enclosed Rotary Disconnect Switch - NEMA 3R 600V
Part Number: ER3R-30N3PB
Quick Summary
Enclosed rotary disconnect switch isolation for 600 V industrial panels, like the Eaton ER3R-30N3PB, ensures safe de-energization and straightforward offline maintenance. Operators often wrestle with live-entry risks, uncoordinated control points, and unclear isolation during line checks. This model helps by providing a non-fused design with a pistol handle for reliable actuation, minimizing arc-flash exposure while meeting routine shutdown needs. The unit carries CE marking and a NEMA 3R enclosure rating, making it suitable for outdoor or damp indoor environments and compliant with common European safety standards. For engineers and procurement teams, it translates into faster commissioning, easier retrofits, and lower long-term maintenance costs, while preserving system integrity and personnel safety.

Eaton Specification Sheet - ER3R-30N3PB
Feature → Business Impact → Application: The ER3R-30N3PB uses a non-fused construction with a pistol-style handle, simplifying isolation procedures and reducing maintenance time. In practice this means faster lockout/tagout and fewer components to service, which lowers downtime during panel changes. Ideal for control panels and equipment racks in manufacturing and utilities where fast, safe isolation is critical. Feature → Business Impact → Application: Rated for 600 V and 30 A, this unit supports common medium-voltage control circuits without overkill or under-specification. The result is reliable isolation for motor starters, switchgear, and feeder circuits, with predictable operation during commissioning and fault conditions. Feature → Business Impact → Application: The NEMA 3R enclosure provides weather-resistant protection for outdoor and damp indoor environments, reducing corrosion and environmental ingress. Operators gain confidence in long-term durability, fewer weather-related faults, and lower replacement costs for enclosures and interlock mechanisms. Feature → Business Impact → Application: CE Marking signals conformity with European safety standards, smoothing procurement in multinational projects and simplifying supplier qualification. This helps specifiers meet regulatory requirements across Europe and other CE-adopting regions while maintaining consistent performance in industrial control panels. Feature → Business Impact → Application: Access to Eaton's Bussmann catalog, datasheets, and specification sheets supports fast engineering decisions and accurate BOMs. The unit's compact footprint and standard catalog references expedite installation planning, panel integration, and cross-compatibility with existing Bussmann components in industrial protection schemes.

FAQs
The ER3R-30N3PB is a non-fused, enclosed rotary disconnect switch rated for 600 V and 30 A, designed to integrate with standard industrial control panels and Bussmann series components. When planning installation, verify enclosure clearance, mounting provisions, and compatibility with neighboring protection devices. Consult the datasheet for mounting dimensions and recommended lockout/tagout procedures to ensure safe, compliant retrofits.
Key specifications include a 600 V voltage rating, 30 A amperage rating, non-fused construction, pistol handle actuation, and a NEMA 3R enclosure rating. These features provide reliable isolation, weather resistance, and straightforward maintenance in both indoor and outdoor applications. The CE marking confirms European safety compliance, making it suitable for multinational projects.
Yes. The ER3R-30N3PB features a NEMA 3R enclosure, which delivers weather-resistant protection suitable for outdoor installations and damp indoor locations. This enables safer, longer-lasting isolation in harsh environments, reducing corrosion risks and related maintenance costs while maintaining regulatory compliance through CE marking.
The ER3R-30N3PB is CE marked, indicating conformity with European safety standards. It also carries a NEMA 3R enclosure rating for outdoor/damp location protection and is designed as a non-fused, pistol-handle disconnect switch suitable for 600 V circuits. These certifications support safer installations and smoother international procurement.
The non-fused, pistol-handle design simplifies isolation and reduces maintenance points, contributing to lower downtime during commissioning and servicing. Coupled with the 600 V/30 A rating and NEMA 3R enclosure, the unit supports longer service intervals in outdoor environments, potentially lowering overall lifecycle costs while improving safety and compliance in critical control applications.
