Cutler-Hammer DH322FRK - 60A, 240V, 3-Pole, Fused Disconnect Switch

The Cutler-Hammer DH322FRK is a rugged fused disconnect switch engineered for dependable electrical isolation in demanding industrial and commercial environments. Built to support lockout/tagout procedures and maintain safe operation under load, this 60A, 240V, 3-Pole unit delivers reliable disconnection when it matters most.

• 60A, 240V, 3-Pole design perfect for three-phase systems, providing straightforward, code-compliant isolation for motors and industrial equipment.
• Fused disconnect adds integrated overcurrent protection, simplifying installation and reducing the need for separate fusing components.
• NEMA 3R enclosure classifies it for reliable performance in indoor or outdoor environments, resisting rain, sun, and dust exposure.
• Lockout/Tagout compatibility supports safe maintenance practices by physically preventing accidental re-energization during service.
• Durable, long-term reliability designed for continuous duty in busy facilities, minimizing downtime and maintenance frequency.

Why the DH322FRK stands out

Unlike non-fused disconnects, the DH322FRK combines switching and overcurrent protection in a single rugged package, ensuring equipment is safely isolated even under load. The 3-pole configuration ensures balanced shutoff across all phases, reducing electrical stress on motors and driven equipment. The robust NEMA 3R enclosure means you can place this switch at service entrances, machine rooms, or outdoor locations with confidence.

Ideal applications and use cases

• Motor control centers and machine disconnects in manufacturing, packaging, or processing facilities
• Outdoor electrical rooms, curbside equipment pads, or loading docks needing weather-resistant protection
• Pumps, conveyors, fans, and HVAC equipment requiring a reliable service disconnect with built-in fusing
• Maintenance shutoff points where lockout/tagout procedures are routinely performed

Practical considerations and best practices

For optimal performance, replace fuses only with the same amperage rating and ensure the line and load are correctly identified during installation. Use the DH322FRK as the primary point of isolation in three-phase systems, coordinating with upstream protection devices to create a layered safety approach. Regular inspections of the enclosure seals and fuse elements help preserve long-term reliability in harsh environment settings.
