General Electric TH3364 - 200A, 600V, 3-Pole, Safety Switch

Engineered by General Electric, the TH3364 200A Safety Switch delivers robust, safe electrical isolation for demanding industrial and commercial environments. Designed for reliable performance in real-world applications, this 3-pole switch provides dependable disconnection under load and is optimized for use with lockout/tagout (LOTO) procedures, helping safeguard maintenance teams during service and testing.

Why choose the GE TH3364 safety switch

• 200A rating, 600V capacity: A versatile main disconnect for three-phase power feeds across a range of applications, from process lines to large equipment feeds.
• 3-Pole design: Supports standard 3-phase electrical systems, delivering clean, reliable isolation for each phase and simplifying integration with existing panel layouts.
• Safe lockout/tagout compatibility: Built to accommodate safe servicing practices, helping teams secure circuits during maintenance and reducing the risk of accidental energization.
• Durable, long-lasting performance: Engineered for enduring operation in busy industrial and commercial settings, delivering consistent disconnection when it’s needed most.

Ideal applications and use cases

• Industrial plants and manufacturing lines requiring a dedicated safety disconnect for equipment and feeders
• Commercial facilities with large motor loads, HVAC systems, or processing equipment that demand reliable isolation
• Maintenance rooms and electrical closets where employees perform routine servicing and need secure, compliant lockout procedures

How the TH3364 compares to typical isolation options

When reliability and safety during maintenance are priorities, a purpose-built safety switch like the TH3364 offers clear advantages over makeshift isolation methods. It provides a defined, verifiable off state for three-phase circuits and integrates smoothly into standard electrical rooms, reducing downtime and boosting overall safety without compromising system performance.

Practical tips for installation and operation

For best results, connect the TH3364 as a main or sectional disconnect where a dedicated isolation device is required for 3-phase circuits. Ensure conductors and terminations are sized to safely carry up to 200A and rated for the system voltage up to 600V. Plan lockout/tagout procedures around the safety switch to protect personnel during maintenance, and train staff to recognize the switch’s off position as the clear, safe state before any service work begins.
