Cutler-Hammer DH361FGK - 30A, 600V, Heavy-Duty, Fusible, Safety Switch

Introducing the Cutler-Hammer DH361FGK, a 30A, 600V heavy-duty fusible safety switch engineered for reliable on/off isolation and precise overcurrent protection in demanding industrial and commercial environments. Model DH361FGK blends rugged durability with a compact footprint, making it an ideal choice for motor disconnects, panelboards, and branch circuits where space is at a premium but safety and protection cannot be compromised.

Why choose this fusible safety switch?

• Fused protection delivers coordinated overcurrent interruption for motors and feeders, helping protect wiring and equipment from fault currents.
• Heavy-duty design stands up to harsh industrial environments, delivering dependable operation under frequent cycling and demanding workloads.
• Compact, maintainable form factor fits tight electrical spaces and simplifies serviceability during routine maintenance or fuse replacement.
• Versatile application: suitable for motor disconnects, panelboard sections, and branch circuits requiring a single, integrated switching and protection solution.
• Clear isolation: when opened, the DH361FGK provides a definite disconnect point, enabling safe servicing and reducing arc-flash risk on live equipment.

Ideal use cases

Factories and warehouses with hot-running motors, conveyor lines, or pumps benefit from a dedicated motor disconnect that can be positioned close to the equipment. Retrofit projects or upgrades that replace older, non-fusible disconnects often choose the DH361FGK for its reliable protection and straightforward maintenance. It also integrates seamlessly into panelboard assemblies where branch-circuit protection and isolation are required in a single device.

What you can count on

With the DH361FGK, you gain predictable performance in demanding environments: a clear on/off state, dependable protection during faults, and straightforward integration into existing electrical infrastructure. This safety switch supports safe maintenance routines and helps minimize downtime by providing a reliable, easy-to-manage protection solution.

Practical deployment tips

• Position the switch for easy access to enable quick isolation during testing and maintenance.
• Coordinate with upstream protection devices to ensure proper selectivity and avoid nuisance trips during startup surges.
• Document the model and ratings (DH361FGK, 30A, 600V) in electrical drawings for efficient future service and replacements.
