DH364UGKN - 200A, 600V, 3-Pole, Fused Disconnect Switch

The DH364UGKN is a rugged, three-pole fused disconnect switch engineered for demanding industrial and commercial environments where safe electrical isolation is non-negotiable. With a 200A current rating and 600V maximum, this unit delivers dependable disconnection under load while supporting robust lockout/tagout procedures to keep maintenance teams safe during service and testing.

Why the DH364UGKN stands out

Designed for reliability in real-world use, this fused disconnect switch blends solid performance with practical safety features. Its three-pole configuration ensures true phase isolation, reducing the risk of partial energization in three-phase systems. When integrated into your electrical distribution or motor control scheme, it provides clear, definitive shutoff paths that technicians can trust during routine maintenance or emergency scenarios.

Key benefits at a glance

• High-capacity performance: 200A rating supports sizable feeders and motor loads common in industrial settings.
• 600V insulation and control: Suitable for a wide range of commercial and industrial power distribution applications.
• Triple-pole isolation: Complete disconnection of all live conductors to minimize arc flash exposure during servicing.
• Fused protection: Integrated fusing provides overcurrent protection in-line with the circuit, helping to shield equipment from short-circuits and overloads.
• Lockout/Tagout friendly: Built to integrate with standard LOTO procedures, promoting safe maintenance practices and regulatory compliance.
• Durability for long-term use: Designed to endure the demands of industrial environments, delivering consistent performance over time.

Ideal applications

• Motor feeders and machine disconnects in manufacturing lines
• Electrical isolation in service panels and distribution boards
• Emergency shutdown points in commercial facilities
• Control enclosures requiring reliable, verifiable isolation during maintenance

How it works in practice

Install the DH364UGKN as the primary isolation point for a circuit or subsystem. When maintenance is needed, apply lockout and tagout devices to the switch handle to prevent accidental re-energization. The fused design provides intended protection while allowing technicians to safely disconnect and reconnect loads under controlled conditions, ensuring equipment and personnel stay protected throughout servicing.
