Eaton R9D3200U - 200A, 600V, 3-Pole, Fused Disconnect Switch

The Eaton R9D3200U is a rugged, purpose-built fused disconnect switch engineered for safe electrical isolation in demanding industrial and commercial environments. With a 200A amperage rating and a 600V rating across 3 poles, this unit delivers dependable disconnection for three-phase circuits when and where you need it most.

Built-in fusing combines switching and overcurrent protection in a single, compact device. This means you can interrupt fault currents directly at the load side, reducing arc exposure and simplifying panel layouts—a practical win for maintenance teams and facility engineers alike.

Key benefits and features:

• Three-pole design ensures complete isolation of all phases for reliable service shutdown and safe lockout/tagout procedures.
• 200A current rating supports service feeders, motors, and equipment without over-sizing components.
• 600V maximum voltage suitable for most industrial power distribution applications.
• Built-in fuses provide immediate overcurrent protection and clear fault clearance, reducing downtime and equipment damage.
• Lockout/tagout compatibility supports safe maintenance practices and personnel safety compliance.

Ideal use cases

Use the Eaton R9D3200U to isolate large motors, pumps, compressors, conveyors, and HVAC equipment in machine rooms, electrical closets, or service panels. It’s particularly valuable wherever a reliable, code-compliant disconnect is required for energy isolation during maintenance or equipment changes.

Why this model stands out

What sets the R9D3200U apart is its integrated approach to protection and switching. Rather than adding separate fuses and a disconnect switch, this unit combines both functions, streamlining installation, reducing wiring complexity, and delivering fast, predictable fault interruption when loads are energized. It’s built to endure the rigors of industrial environments and to support your lockout/tagout programs with confidence.

Practical tips

• Pair with the correct fuse type and rating according to your motor or load requirements (consult your electrical schematic or installer guide).
• Coordinate with your facility’s lockout/tagout procedures to maximize worker safety during maintenance windows.
• Ensure enclosure clearance and cable entry aligns with your installation site to simplify wiring and future servicing.
