This 30A, 600V fusible switch delivers precise on/off isolation and robust overcurrent protection, making it a trusted cornerstone for motor disconnects, panelboards, and branch circuit protection in challenging electrical setups.

• Model: TH3361
• Amperage: 30 A
• Voltage: 600 V
• Poles: 3-Pole
• Duty: Heavy-Duty
• Switch Type: Fusible safety switch for reliable overcurrent protection
• Applications: Ideal for motor disconnects, panelboards, and branch circuits where a compact, maintainable solution is required

Why this TH3361 stands out in demanding environments

Designed to endure the vibrations, dust, and temperature fluctuations common in factories and warehouses, the TH3361 provides a dependable isolation point that keeps equipment safe during maintenance and startup. The three-pole design ensures complete phase separation, which is critical for safe servicing of three-phase motors and equipment. As a fusible switch, it adds an essential layer of overcurrent protection right at the source, helping to prevent damage to downstream components and reducing downtime from electrical faults.

Practical uses and scenarios

Whether you're configuring a new three-phase system or upgrading an existing setup, the GE TH3361 fits neatly where space is at a premium. Use it to:

• Isolate motors on conveyor lines, pumps, and fans for safe maintenance
• Provide a dedicated disconnect for panelboard sections feeding critical machinery
• Protect branch circuits supplying HVAC, processing equipment, or lighting in large commercial spaces

Maintenance, safety, and installation tips

For long-lasting performance, pair the TH3361 with proper wiring practices and code-compliant maintenance routines. Always:

• Confirm the circuit is de-energized andappropriately locked out before any service
• Follow local electrical codes when wiring and selecting compatible fuses within the fusible switch design
• Inspect connections for tightness and signs of overheating during routine checks
• Use the switch as the designated isolation point to facilitate safe startup and shutdown procedures

Who benefits most

The GE TH3361 is an excellent fit for facilities seeking a compact, rugged, high-availability safety switch for three-phase systems. It’s well-suited for manufacturing floors, processing plants, large warehouses, and commercial spaces requiring reliable motor protection and straightforward, maintainable circuit isolation.
