GE TH3365 - 400A, 600V, 3-Pole, Fusible, Disconnect Switch

GE TH3365 is a rugged 400A, 600V fusible disconnect switch engineered for dependable on/off isolation and precise overcurrent protection in demanding industrial and commercial environments. Designed to withstand the grind of harsh climates, vibration, and busy electrical rooms, this 3-pole disconnect consolidates control and protection in a compact, maintainable package that suits limited-space panel enclosures and motor control centers.

Key specifications

• Model: TH3365
• Amperage: 400A
• Voltage: 600V
• Poles: 3-Pole
• Fused: Fusible

Why a fusible disconnect? The TH3365 delivers both reliable isolation and targeted overcurrent protection in a single device. This means fewer components to manage, faster fault isolation, and cleaner protection for three-phase circuits. It’s especially advantageous in applications where motors, conveyors, pumps, and large fans demand immediate disconnection in fault conditions while minimizing downstream damage.

Ideal use cases

• Motor disconnects in manufacturing lines, HVAC systems, and processing equipment
• Panelboard feeder protection where compact, integrated protection is preferred
• Branch circuit protection for critical loads that require quick isolation and clear fault boundaries

What makes it stand out

• Robust, compact design: Built for industrial duty, the TH3365 fits tight spaces without sacrificing protection or reliability.
• Three-phase protection in one unit: With a 3-Pole configuration, it handles balanced three-phase circuits efficiently, simplifying wiring and maintenance.
• Easy maintenance approach: The fusible design enables straightforward fuse replacement and field servicing, helping minimize downtime.
• Clear isolation with integrated protection: You get both a reliable disconnect and overcurrent protection in a single, purpose-built switchgear component.

Practical considerations when deploying the GE TH3365: plan for a straightforward installation in panelboards or motor control centers, ensure compatible fuse elements are on hand for fast replacements, and follow standard lockout/tagout procedures during maintenance. This disconnect switch is purpose-built for environments where reliable isolation and targeted protection keep motors and circuits safe and available when you need them most.
