Eaton DH321NGK - 30A, 240V, 3-Pole, Fused Disconnect Switch

Eaton DH321NGK is a rugged, high‑performance fused disconnect switch designed for industrial and commercial environments that demand safe, reliable electrical isolation. With a 30A rating, 240V operation, and a true 3‑pole configuration, it provides robust protection for motor feeders and control circuits while supporting safe maintenance through lockout/tagout (LOTO) procedures.

• Safe, lockout/tagout compatible isolation—a dedicated disconnect point that helps technicians secure power during servicing, reducing risk and downtime.
• Under-load disconnection—engineered to interrupt current reliably even when equipment is energized, minimizing arcing and equipment stress.
• Three‑pole isolation—ensures all phases are opened simultaneously for comprehensive safety during maintenance and fault scenarios.
• Durable, industrial‑grade construction—built to withstand demanding environments and deliver long‑term reliability in continuous operation.
• Easy integration—designed to fit into standard control panels and motor circuits, simplifying wiring and panel layouts.

• Ideal applications—motor control centers, feeder circuits, conveyors, pumps, and HVAC equipment within manufacturing, processing, and commercial facilities requiring a clear isolation point.
• LOTO compliance support—a practical solution for safe servicing workflows and regulatory safety practices in the field.
