GE TH3361R - 30A, 600V, 3-Pole, Fused Disconnect Switch

The GE TH3361R fused disconnect switch is built for reliability in demanding industrial and commercial environments where safe electrical isolation is non‑negotiable. With a 30A current rating and a 600V operating envelope across a 3‑pole configuration, it delivers a clean, definitive disconnect when maintenance or servicing is required, while the integrated fusing provides essential short‑circuit protection to safeguard equipment and personnel.

Designed to perform in challenging conditions, its NEMA 3R enclosure rating offers dependable protection for outdoor or damp locations. This makes the TH3361R a versatile choice for outdoor panels, switchgear rooms, and exposed electrical installations where weather resistance and quiet operation matter as much as safety. It also supports proper lockout/tagout procedures, reinforcing safe maintenance practices and reducing downtime caused by accidental energization.

• Amperage rating: 30A
• Voltage rating: 600V
• Poles: 3‑Pole
• Enclosure rating: NEMA 3R
• Product type: Fused Disconnect Switch
• Brand/model: GE TH3361R

Ideal applications and use cases

This fused disconnect is well suited for facilities that require reliable isolation of three‑phase circuits. Use it to service motors, conveyors, pumps, and HVAC systems, or as a service disconnect feeding switchgear and motor control centers. It’s particularly valuable in spaces where outdoor installations or damp environments are a reality, and safety procedures around servicing—like lockout/tagout—must be strictly observed.

What makes the TH3361R stand out

• designed to interrupt current cleanly, reducing arcing and wear on downstream equipment.
• Three‑pole isolation: ensures all live conductors are disconnected simultaneously for true safety during maintenance.
• Weather‑ready enclosure: the NEMA 3R rating expands where you can deploy this switch—from indoor panels to outdoor installations.
• Maintenance‑friendly safety: built to support lockout/tagout workflows, helping facilities stay compliant and protect workers.

Practical guidance for deployment

Integrate the GE TH3361R into three‑phase electrical distributions where safe and definitive isolation is required. Plan for the appropriate fuse configuration to complement system protection, and pair with proper lockout/tagout devices to maximize maintenance safety. Regularly inspect the enclosure and connections, ensuring the integrity of the enclosure seals and the reliability of the disconnect function in demanding environments.
