Eaton Cutler-Hammer DH364UGK 200A 3P 600V Safety Switch, NEMA 1, Fusible, Non-Fusible | AmpState

The Eaton Cutler-Hammer DH364UGK is a rugged, ready-to-deploy safety switch designed to safely disconnect and isolate power at the point of use. Built for reliability in demanding industrial environments, this 200 A, 3-pole device delivers clean, compliant isolation for three-phase circuits at up to 600 V, making it a dependable cornerstone for motor control and power distribution systems.

What makes the DH364UGK stand out

• NEMA 1 enclosure engineered for indoor service environments, combining solid protection with straightforward maintenance access.
• Dual configuration options available as Fusible or Non-Fusible, giving you the flexibility to tailor protection to your system needs without changing the form factor.
• Industry-standard size and wiring footprint that supports retrofit projects where part numbers must stay consistent, reducing planning and install downtime.
• Three-pole design at 200 A handles three-phase power cleanly, with clear isolation to simplify motor control, feeders, and critical equipment disconnects.
• Operational clarity and safety—manual operation with unambiguous off/on positioning, helping technicians verify status at a glance during maintenance and troubleshooting.

Ideal applications and use cases

• Equipment disconnect and isolation at the point of use in manufacturing lines, pumps, conveyors, and large control panels.
• Retrofit projects where keeping the exact part number is important for inventory, documentation, and service continuity.
• Maintenance planning for facilities that require quick, reliable disconnection to safely service downstream equipment.
• Electrical rooms and industrial enclosures needing a robust NEMA 1 solution that can be configured for either fuse protection or direct-disconnect use.

Why customers choose this configuration

• Flexibility without compromise: Choose fusible protection when you need overcurrent protection integrated into the switch, or non-fusible when you want a straightforward disconnect.
• Fewer part numbers, faster procurement: The DH364UGK provides a consistent part identity that simplifies stocking, ordering, and maintenance planning.
• Clear safety workflow: Rapid, safe de-energization facilitates safer maintenance windows and reduces downtime during service events.
