General Electric TH3364 - 200A, 600V, 3-Pole, Fused Disconnect Switch

The General Electric TH3364 200A, 600V, 3-Pole Fused Disconnect Switch is engineered for tough industrial and commercial environments where safe, reliable electrical isolation is non-negotiable. With a three-pole configuration, it delivers true three-phase isolation, making maintenance and service work safer and more predictable. Designed to support proper lockout/tagout procedures, this switch helps crews prevent unexpected re-energization during servicing while maintaining a clear, auditable safety workflow.

Key advantages that matter in the field

• Three-pole fused design provides comprehensive isolation for all live conductors in a three-phase system, reducing the risk of arc-flash exposure during maintenance.
• 200A amperage rating and 600V voltage rating tailor the TH3364 to mid- to large-scale equipment and distribution circuits common in industrial settings.
• Integrated fuse protection adds overcurrent protection at the point of isolation, helping safeguard downstream equipment and wiring from faults.
• Lockout/Tagout compatibility supports compliant maintenance practices, ensuring the switch cannot be re-energized until safety procedures are completed.
• Durable, purpose-built construction designed to withstand the rigors of daily use in demanding environments, delivering dependable disconnection under load over the long term.

Ideal use cases

• Maintenance shutdowns on production lines where safe, verified isolation is essential before servicing motors, drives, or transformers.
• Electrical rooms and feeders in manufacturing facilities and large commercial buildings requiring robust, code-compliant isolation points.
• Emergency or routine disposition of power for equipment during fault diagnosis, preventative maintenance, or upgrades.

Who benefits from the TH3364

Electrical engineers, plant managers, and maintenance teams who need a reliable, enforceable isolation solution for three-phase circuits. The TH3364 combines clear electrical protection with practical safety workflows, helping teams stay compliant while minimizing downtime.
