GE THN3361 - 30A, 600V, 3-Pole, Heavy-Duty, Fusible, Safety Switch

Meet the GE THN3361, a 30A, 600V, 3-Pole heavy-duty fusible safety switch designed to deliver reliable on/off isolation and precise overcurrent protection in demanding industrial and commercial settings. Built to withstand rigorous use, this switch provides a robust solution for protecting your motors, panels, and branch circuits when reliability and safety matter most.

Why this fusible safety switch stands out

• Fusible protection in a compact package: integrated fuses interrupt fault currents quickly, helping to shield equipment from damage while saving valuable panel space.
• Three-pole configuration: ensures all live conductors are simultaneously isolated, reducing the risk of backfeed and accidental energization during maintenance.
• 600V rating: well-suited for medium- to high-voltage motor circuits and distribution panels, providing dependable protection across a range of applications.
• Heavy-duty construction: designed to endure demanding environments, frequent switching, and the rigors of industrial operation.

Ideal applications

The THN3361 is purpose-built for motor disconnects, panelboards, and branch circuit protection where a compact, maintainable fusible switch is required. Practical use cases include:

• Motor control lines in manufacturing, packaging, and processing facilities where rapid, clean isolation is essential during maintenance or fault events.
• Electrical distribution panels in industrial environments needing reliable disciplinary protection without sacrificing space.
• Service disconnects on equipment that benefits from fuse-based protection to limit fault energy and protect downstream devices.

Protection you can trust

By combining visible isolation with effective fault interruption, the THN3361 helps prevent equipment damage and enhances technician safety during servicing. The three-pole design ensures comprehensive de-energization of all conductors, supporting safer work conditions and minimizing the risk of accidental shocks or arc hazards.

Installation and maintenance guidance

• Confirm fuse type and rating match your circuit and motor specifications before installation.
• Install within standard electrical enclosures or panelboards designed to accept 3-pole fusible safety switches.
• Schedule routine inspections to check for signs of wear, corrosion, loose terminals, or fuse linkage issues that could affect performance.
