GE TH3364 - 200A, 600V, 3-Pole, Heavy Duty Fused Disconnect Switch

The GE TH3364 Heavy Duty Fused Disconnect Switch is engineered for rugged industrial and commercial environments where safe electrical isolation and dependable disconnection under load matter most. With a 3-pole design, a 200A rating, and a 600V maximum, this switch delivers reliable power control for demanding applications while supporting essential lockout/tagout procedures to protect maintenance teams during service.

Why the GE TH3364 stands out

• Full-phase isolation with a 3-pole configuration ensures complete electrical separation of all conductors during servicing, reducing the risk of accidental energization.
• Heavy-duty fused protection provides immediate overcurrent interruption, helping safeguard motors, feeders, and connected equipment from faults and short circuits.
• Indoor, durable enclosure with a NEMA 1 rating offers reliable protection in controlled indoor spaces—from electrical rooms to service bays—against dust and incidental contact.
• Lockout/tagout compatibility supports safety programs by allowing secure padlocking of the switch during maintenance, minimizing downtime and safeguarding personnel.
• Long-term reliability built to withstand the rigors of continuous operation in demanding environments, reducing maintenance cycles and unexpected outages.

Ideal use cases

• Motor feeders and large equipment lines in manufacturing, packaging, and material handling facilities.
• Emergency and service disconnects for HVAC systems, pumps, conveyors, and power distribution panels.
• Situations requiring quick, safe isolation with replaceable fuses to protect downstream equipment during maintenance.

Practical considerations and installation tips

• Use the TH3364 for indoor power isolation where 200A loads and 600V systems are standard, ensuring proper alignment with your distribution layout.
• Pair the switch with appropriate fuses and ensure fuse replacements are performed by qualified personnel to maintain protective integrity.
• Plan for easy access to the disconnect for routine maintenance and testing, and position the switch to support clear visibility of status indicators.
• Integrate with your lockout/tagout program: attach standard padlocks to the switch handle to enforce safe servicing procedures.
• Compare the fused approach to non-fused disconnects: the TH3364 provides built-in overcurrent protection, enabling quicker fault response and reduced equipment risk during abnormal conditions.

For facilities seeking robust, reliable electrical isolation with straightforward maintenance, the GE TH3364 200A, 600V, 3-Pole Heavy Duty Fused Disconnect Switch is purpose-built to keep operations flowing smoothly while prioritizing safety and longevity.
