GE TH4323 - 100A, 3-Pole, Fused Disconnect Switch

GE TH4323 stands as a dedicated solution for industrial and commercial environments that demand a reliable, code-conscious isolation point. This 100A, 3-Pole Fused Disconnect Switch is built to deliver safe electrical isolation, precise disconnection under load, and durable performance across demanding settings.

Why the GE TH4323 Stands Out

Designed to support proper lockout/tagout procedures and maintain safe working conditions, the TH4323 consolidates protection and disconnection in a single, robust package. Its fused design provides immediate overcurrent protection while ensuring all three conductors can be safely isolated, reducing arc exposure and simplifying maintenance protocols.

Key Benefits

• Reliable 100A, 3-Pole isolation: Simultaneous disconnection of all lines ensures complete de-energization of motor circuits and equipment.
• Integrated fuse protection: Built to interrupt fault currents and protect downstream equipment, cables, and control circuits.
• NEMA 1 enclosure: Indoor, dry-location suitability with a sturdy enclosure that stands up to everyday industrial use.
• Lockout/Tagout friendly: Designed to accommodate standard lockout/tagout practices, helping keep maintenance personnel safe during servicing.
• Long-term durability: Built for consistent performance under load, with components selected for longevity in busy electrical environments.

Ideal Use Cases

The GE TH4323 is well-suited for service disconnects and isolation points in a wide range of applications, including:

• Motor-driven equipment in manufacturing, processing lines, and conveyors
• Industrial machinery and HVAC systems requiring safe de-energization during maintenance
• Commercial electrical rooms and equipment enclosures where dependable isolation is essential

What to Expect in Practice

When your team needs a dependable, code-aligned disconnect, the TH4323 delivers a clear, unambiguous isolation path. The three-pole design ensures that all hot conductors can be locked out, while the fused architecture protects circuits from overloads. This combination minimizes downtime, simplifies fault tracing, and enhances overall electrical safety in high-demand environments.

Practical Installation Considerations

Install in indoor, dry environments where a robust, all-in-one isolation and protection solution is needed. Plan for proper wiring to accommodate a 3-pole configuration and ensure that lockout/tagout devices can be applied securely to the disconnect handle or designated maintenance point. Regularly inspect fuses and connections to maintain reliable performance and extend service life.
