GE TH3221R - 30A, 120/240V, 2-Pole, Fused Disconnect Switch

The GE TH3221R is a high-performance fused disconnect switch engineered for demanding industrial and commercial environments where safe electrical isolation and reliable disconnection under load are essential. With a 30A rating and a 120/240V supply, this 2-pole disconnect provides precise control over power shutdowns while supporting proper lockout/tagout procedures to keep maintenance teams safe.

• Power and configuration: 30A amperage, 120/240V voltage, 2-pole design for complete isolation of both hot conductors.
• Fused protection: Integrated fusing delivers dependable fault interruption, helping protect equipment and wiring from overloads and short circuits.
• Safety and lockout/tagout: Designed to support robust lockout/tagout practices, enabling secure, compliant maintenance and service work.
• Durable, reliable performance: Built for long-term durability in challenging environments, delivering consistent disconnection when needed.

Whether you’re powering industrial machinery, processing lines, or commercial equipment racks, the TH3221R gives you a trusted, hands-on disconnect that electricians and maintenance teams can rely on. The combination of a fused design and a 2-pole configuration means you can safely isolate both conductors, ensuring full de-energization before service or repairs begin.

Key use cases

• Electrical isolation for service and maintenance on machines and controllers in manufacturing facilities
• Temporary power shutdowns in commercial HVAC, pumps, conveyors, and motor-driven equipment
• Standby disconnects in control panels where quick, predictable power disconnection is required

Who benefits most

• Electrical technicians and maintenance teams requiring reliable, code-conscious isolation
• Facilities managers seeking durable, low-maintenance disconnect solutions
• Contractors installing or upgrading industrial control systems and safety interlocks

Practical guidance for deployment

Install the GE TH3221R as part of a safe, lockable disconnect plan. Verify the circuit is de-energized before servicing, and pair the device with appropriate lockout/tagout devices and warning tags. Its fused design helps minimize risk of damage during fault conditions, while the 2-pole arrangement ensures both hot lines are isolated for true off-state status.

Frequently considered questions

What does 2-pole mean for my setup? It means both hot conductors are disconnected, providing complete isolation for 120/240V circuits and enhancing safety during maintenance.

Why choose a fused disconnect switch? The fused elements interrupt fault currents rapidly and add an extra layer of protection for wiring and connected equipment beyond a standard switch.

Is this suitable for industrial control panels? Yes—its rugged design and compatibility with lockout/tagout protocols make it a strong fit for control panels and other industrial applications where reliable isolation is critical.
