GE TH3363 - 100A, Fused Disconnect Switch

The GE TH3363 100A Fused Disconnect Switch is engineered to deliver safe, reliable electrical isolation in industrial and commercial settings where maintenance and uptime matter. By pairing fuse protection with a sturdy isolation switch, it provides a clear, authenticated break in the circuit while actively safeguarding equipment and personnel during servicing.

• 100A fused disconnect for dependable isolation — designed to reliably interrupt power when service is required, helping technicians work safely and efficiently.
• Integrated fuse protection — the fuse elements offer overcurrent protection, reducing the risk of damage from short circuits while the switch provides the necessary isolation point.
• Lockout/Tagout (LOTO) compatibility — built to support standard safety procedures, enabling secure de-energization during maintenance and compliance with safety protocols.
• Durable, long‑lasting construction — designed to withstand demanding industrial environments, including heat, dust, and vibration, for reliable performance over time.
• Easy integration into control and power layouts — serves as a clear isolation point for feeders, motors, or equipment, simplifying wiring and system architecture.
• Reliable disconnection under load — engineered to interrupt current cleanly when opened, helping minimize arc risk and protect connected assets during maintenance.

Ideal users and use scenarios

The TH3363 is well-suited for facilities managers, maintenance engineers, and electrical technicians in factories, warehouses, and commercial buildings who need a robust, compliant isolation solution. Use it as the primary isolation point for feeders and equipment, incorporate it into service entrances, or deploy it wherever a dependable 100A disconnect with fuse protection is required.

Why choose the GE TH3363

Unlike standalone switches or non-fused disconnects, the TH3363 combines protective fusing with a clear isolation path in a single, compact unit. This reduces component count, simplifies wiring, and supports safer maintenance workflows by enabling immediate, protected de-energization when work is performed on energized circuits.

Practical guidance for best results

• Follow established lockout/tagout procedures to maximize on-site safety during maintenance.
• Designate the TH3363 as the official isolation point for relevant equipment and feeders.
• Schedule regular inspection and fuse replacement as part of your preventive maintenance program to maintain optimal performance.

With the GE TH3363, you gain a dependable 100A fused disconnect switch that delivers clear isolation, integrated protection, and peace of mind for safe, efficient operation across industrial and commercial electrical systems.
