Eaton Cutler-Hammer DH323FGK - 100A, 240V, 3-Pole, Fused Disconnect Switch

The Eaton Cutler-Hammer DH323FGK is a rugged, purpose-built fused disconnect switch designed to deliver dependable electrical isolation in demanding industrial and commercial environments. With a 100A rating at 240V and a 3-pole configuration, this disconnect provides secure three-phase disconnection and direct protection for downstream equipment and circuits.

Key features

• 100-ampere capacity at 240V three‑phase operation for reliable control of motors, transformers, and feeders
• Three-pole design ensures complete isolation of all phases, reducing arc risk and facilitating safe maintenance
• Fused disconnect switch with built-in overcurrent protection minimizes fault propagation and protects downstream components
• NEMA 1 enclosure suitable for indoor installations, backed by Eaton's durability and build quality
• Support for lockout/tagout procedures to meet safety standards during service and repair

Why choose this fused disconnect

Choosing a fused disconnect like the DH323FGK means you’re pairing isolation with active protection. Unlike simple disconnects, the fused assembly provides immediate fault interruption, helps meet safety regulations, and curtails equipment damage during faults or overloads. The 3-pole arrangement ensures all conductors are safely isolated, giving technicians a clear, unambiguous de-energized state for maintenance.

Ideal use cases

Best suited for motor circuits in manufacturing, processing lines, and building services where reliable isolation is essential. It’s a solid fit for service disconnects at machine rooms, control panels, and distribution panels where 3-phase power is standard and lockout/tagout protocols are in place.

Practical considerations

• Ensure compatible fuses are installed per manufacturer specifications and local electrical codes
• Coordinate with upstream breakers and downstream devices to prevent nuisance trips and ensure coordinated protection
• Mount in a clean, dry indoor environment to preserve NEMA 1 enclosure integrity
• Label clearly and maintain lockout/tagout provisions to maximize maintenance safety

With the Eaton Cutler-Hammer DH323FGK, you get a trusted solution that blends robust isolation with proactive protection, designed to keep equipment safe, downtime minimal, and maintenance workflows streamlined.
