Eaton DH364UWK - 200A, 600V, 3-Pole, Safety Switch

The Eaton DH364UWK is a high-performance safety switch engineered for industrial and commercial electrical systems that demand safe, reliable isolation. With a robust 200A rating, 600V maximum, and a 3-pole configuration, this switch provides true, all-phase isolation to support clean, safe maintenance and dependable operation across demanding environments. It’s built to support proper lockout/tagout procedures and delivers dependable disconnection under load, helping protect personnel and equipment over the long term.

Key features that matter in the field

• 200A amperage rating meets the needs of medium-to-large electrical feeders and motor loads without overtaxing the control circuit.
• 600V voltage rating broadens compatibility with common industrial power systems and motor circuits.
• 3-Pole configuration ensures simultaneous disconnection of all three phases, reducing the risk of partial isolation and arc flash exposure during maintenance.
• Safe, proven disconnection under load designed to interrupt circuits reliably when equipment is energized, supporting safe startup and routine servicing.
• Durable construction built for ongoing duty in busy facilities, handling repetitive operation and environmental demands without compromising performance.
• Lockout/tagout readiness structure integrates with standard safety protocols, helping facilities meet their safety program requirements.

Why this matters for your operation

In any facility with motors, feeders, or automated lines, the ability to isolate power safely is non-negotiable. The DH364UWK delivers a clear, definitive disconnect that maintenance personnel can trust, reducing the risk of accidental energization during service. Its three-phase isolation minimizes potential arcing and provides a controlled point of safe access for servicing, diagnostics, or routine inspections. The result is smoother maintenance windows, less downtime, and a safer work environment for technicians and operators alike.

Ideal use cases

• Motor control centers and large equipment feeds where reliable service disconnect is essential.
• Industrial automation panels and process lines requiring quick, definitive isolation for safety and compliance.
• Facility power feeders serving heavy machinery, compressors, pumps, and conveyor systems.
• Maintenance shutoffs in commercial-industrial environments where lockout/tagout practices are standard.

Who benefits from the Eaton DH364UWK

• Electrical engineers and facilities managers seeking a dependable, code-compatible safety switch for critical power sections.
• Maintenance teams responsible for safe servicing of energized equipment and the prevention of unexpected startups.
• Electrical contractors installing or upgrading safety switch infrastructure in manufacturing plants and large commercial spaces.

Practical tips for deployment and use

• Pair the DH364UWK with established lockout/tagout procedures to ensure a consistent, auditable safety workflow during maintenance.
• Verify its handling and mounting within an appropriately sized enclosure that accommodates conductors, cables, and clearance for safe operation.
• Schedule periodic inspections of the switch mechanism to confirm smooth operation and reliable signaling of the disconnection state.
• Use it as a primary safety disconnect where three-phase electrical isolation is required, rather than a secondary backup switch, to maximize protection and efficiency.

Choosing the Eaton DH364UWK means selecting a proven safety switch designed for real-world industrial demand. Its combination of 200A capacity, 600V versatility, and true three-pole isolation provides a dependable foundation for safe maintenance, reliable equipment protection, and streamlined safety workflows across facilities that rely on consistent, robust electrical performance.
