Eaton R9C3030U - 30A, 3-Pole, Fused Disconnect Switch

The Eaton R9C3030U is a purpose-built 30A, 3-Pole Fused Disconnect Switch designed to deliver reliable electrical isolation in demanding industrial and commercial environments. Built to endure daily maintenance cycles and provide safe service access, this switch ensures you can isolate circuits confidently, even under load.

Why this fused disconnect matters

• Three-pole design for three-phase systems: Seamless integration with standard 3‑phase motors and equipment, enabling efficient control across multiple conductors.
• 30 Ampere rating: Suited for mid-sized motor circuits, pumps, conveyors, and other machinery without overloading the disconnect device.
• Fused protection: Adds a layer of overcurrent protection to downstream equipment, helping limit fault currents and shorten fault duration in the event of a short circuit.
• Lockout/Tagout readiness: Designed to support safe lockout/tagout procedures, contributing to safer maintenance and servicing workflows.
• Durable, purpose-built for performance: Specifically selected for environments where dependable disconnection under load is critical for worker safety and uptime.

Ideal use cases

Choose the Eaton R9C3030U for applications that require dependable isolation and protection, including:

• 3‑phase motors, fans, and pumps in manufacturing or processing lines
• Conveyor systems and material handling equipment
• HVAC equipment in large commercial facilities
• Localized service points in switchgear and electrical rooms

What sets it apart

Unlike non-fused disconnects, the R9C3030U combines isolation with protective fusing, delivering enhanced protection for downstream devices and reducing the risk of cascading faults. Its Eaton engineering ensures consistent performance in environments where uptime and safety are non-negotiable.

Practical considerations and tips

• Pair this switch with compatible fusing and enclosure configurations to ensure a complete, compliant isolation solution.
• Use proper lockout/tagout procedures during maintenance to maximize personnel safety when circuits are de-energized.
• Verify wiring diagrams and labeling align with your 3‑phase system layout to ensure correct pole alignment and disconnection behavior.
